1. WÄRTSILÄ G-BEARINGS MODULAR SYSTEM Journal plain bearings are important components for modern high performance rotating machinery. Wärtsilä offers a complete range of state-of-the-art plain bearings to cope with the highest demands in the industry. Wärtsilä G-bearings work either fully hydrodynamic or combined hydrodynamic / hydrostatically, creating a separating film of lubricant between the shaft and bearing shell. This ensures long lifetime, high operational safety and low life cycle cost. G-Bearings are designed in a flexible modular system, allowing the assembly of project specific bearings from a wide range of standard components. Short lead times and spare parts availability can be combined with maximum flexibility to suit the individual application. Wärtsilä is able to adapt the standard components for bespoke design solutions, for example if an existing non-din bearing is replaced, or additional machining is required on the bearing to accommodate additional functions. 1.1. APPLICATIONS G-Bearings are successfully used in a wide range of industrial applications, for example: electrical motors electrical generators turbo generators hydro generators blowers and fans compressors water turbines 1.2. BEARING SIZE RANGE The Wärtsilä G-Bearing standard range covers pedestal bearings GP, sizes 9 71 from 900 mm shaft diameter and GM center flange / GF end flange bearings size 9 45 for shafts 560 mm. Additional sizes and types are available upon request. 1.3. HEAT DISSIPATION Frictional heat generated can be dissipated by radiation and natural convection. If this is not sufficient, the bearing oil sump can be cooled by a submerged water/oil heat exchanger. In cases where higher power losses are to be dissipated, an external oil supply system can be connected. The tank volume should be approximately 5 times the required oil flow per minute to allow sufficient relaxation of the oil. Highly loaded axial parts can be separately connected to an external oil supply to maximize operational safety. 3

3. MAIN COMPONENTS AND FEATURES DESCRIPTION 3.1. BEARING HOUSING Bearing housings are made of high quality cast iron. Standard housing material is GG30 up to size 28; from size 35 housings are produced in GGG40 to allow greater stiffness in cases of high axial load. Other housing materials such as cast steel are available upon request. Wärtsilä G-Bearing housings are of finned type to maximize the effect of heat dissipation. Larger pedestal bearings are smooth. The spherical bearing shell seat diverts both radial and axial loads evenly into the bearing housing and is designed for high load carrying capacity, making the bearings insensitive to misalignment. The greater stiffness of the housings also affects the rotor dynamic, i.e. critical speed, in a positive manner. Tapped holes for oil inlet and outlet, as well as for temperature and oil level monitoring are available on both sides of the bearing housing. All housings are prepared for 3 standard accelerometers. If required, provisions for shaft vibration measurement instruments or oil coolers can also be provided. The split design allows easy removal of the bearings with rotor in place, once seals, seal carriers and bearing shell have been removed. 3.2. BEARING SHELL The bearing shells are made of a high quality steel body, lined with white metal. The metallic bonding is of highest quality and continuously monitored and protocolled by ultrasonic testing. Depending on the application, different types of bearing shells are used, for example bearing shells with cylindrical, two-lobe or four-lobe bore profile. Different thrust parts are used depending on the thrust load. Q-shells are used as non-locating bearings and have no thrust faces B-shells have plain white metal shoulders with oil grooves and can serve as either nonlocating bearings, or to absorb temporary bumping loads, for example during testing K-shells use taper land thrust faces for high thrust loads in both directions J-shells use taper land thrust faces for high thrust loads as K type, but in only one direction of rotation A-shells with tilting thrust pads have maximum axial load carrying capacity. In most cases, the bearing shell can be equipped with a loose oil ring. Special bearing shell designs, according customer requirements, are available upon request. 3.3. ELECTRICAL INSULATION In order to prevent stray current, internally insulated bearings can be supplied. To achieve this, the spherical seating is coated with high strength synthetic material. The bearings can also be equipped with ground strap. Floating labyrinth seals type 10 (IP44) are electrically insulating. Metallic seals can be insulated by intermediate insulating layers. 3.4. TEMPERATURE CONTROL Provisions for radial bearing temperature measurement with standard commercially available thermo sensors are located on both sides of the housing. For bearings with high thrust loads (type A), additional thermometers for the thrust part can be added. Direct thermometers can be installed to monitor the oil sump temperature visually. 5

3.5. OIL SELECTION Generally, any non-alloyed brand of mineral oil can be used. The correct viscosity for each operating condition must be checked by computerized calculations. These calculation sheets can be provided on request. 3.6. OIL SUPPLY and COOLING Under normal circumstances, oil lubrication is achieved through a loose oil ring. In addition, an external oil circulation system can be connected. In this case, the oil ring provides an emergency oil supply during rundown in the event of failure of the circulation system. Natural lubrication: Frictional heat is dissipated from the housing by radiation and convection. The necessary oil supply to form the hydrodynamic oil film is provided by the standard loose oil ring. For marine applications, loose oil rings are equipped with an oil ring guide, which allow coping with typical inclinations during sea operation. Loose oil rings are used up to 20 m/s shaft circumferential speed, 26 m/s at overspeed conditions. Circulating pumps: In case of larger oil requirement for taper land or tilting pad thrust faces, a circulating oil pump can be used. It sucks oil from the oil sump and pumps it directly to the loaded thrust parts. If required, an additional heat exchanger in the pump circuit can be used to cool the oil. External lubrication: If friction losses increase and / or thrust parts require additional oil quantities, external lubrication is the method of choice. In bearings with a loose oil ring, the ring serves as backup in case of failure of the oil supply. G-Bearings are equipped with connections for external oil supply on both the left and right side. For larger oil demand in highly loaded thrust parts with round tilting pads, additional separate oil feeds for the thrust bearings can be used. 3.7. OIL OUTLET The standard oil outlet connection sizes and maximum oil quantities can be found in the following table. Connecting pipes must be installed in a minimum 15 angle and with sufficient cross section to make sure that the oil flows freely from the bearing, to avoid overfilling and subsequent leakage.

SEALS In most cases, it is sufficient to equip slide bearings with floating labyrinth seals for protection against objects and water splashing. These labyrinth seals follow possible displacements of the shaft. They can be easily installed and removed due to their split design and accessibility. Instead of floating seals, rigid metallic seals can be used. They consist of two sets of labyrinths and are easily adjusted during assembly. With both seal types, the grade of protection achieved is IP 44. In connection with additional baffles, protection IP 55 can be reached. Special seal types can be supplied upon request (e.g. IP56). If the shaft ends in the bearing, an end cover can be mounted. An overview of the available seal types can be found on page 23. 3.9. MACHINE SEAL (GF) and PRESSURE SEAL (GM) End flange bearings GF can be equipped with an optional inside machine seal. An overview of Machine Seal range dimensions can be found on page 19. Center flange bearings GM are equipped with a standard internal split Pressure Seal. The cavity created between this seal and the bearing is connected to the outside ambient by flexible hoses. It allows pressure equalization between the seal inside the bearing and outside, to prevent leakage of oil through the seals, and pressure-build-up in the bearing. 6

4. BEARING SELECTION The following table will assist you initially in determining the size of the G-type bearing. In case of an order or for a concrete application it is necessary to perform a computerized calculation, in order to consider the reciprocal influence of operating parameters. The same applies if higher loads than those shown in the table are to be absorbed by the bearings. 4.1. RADIAL LOADS Radial load F R is considered as permanent (maximum value) and applied in a downwards direction. Load values for other directions are available upon request. Specific loads higher than 2,5 MPa, longer operation at turning speed or high start-up load may require hydrostatic lifting, please check with our application engineers. 4.2. AXIAL LOADS Thrust load F A is considered as permanent load applied on the different thrust surfaces. Small temporary loads are taken up by plain shoulders on the bearing shell (locating bearing; type B).

EMPIRICAL GUIDELINE VALUES FOR THE MEAN RELATIVE BEARING CLEARANCE The bearing clearance should preferably be 0,56 0,8 1,12 1,32 1,6 1,9 2,24 3,15 As given in DIN 31698 in which the mean relative bearing clearance are graded according to the preferred number series. The values given in the next table are general empirical guideline values for ψm, both the dependence on the circumferential speed and the diameter having been taken into account. The reason for this is the fact that for the same Sommerfeld numbers and same B/D radios, the temperature measured in the bearing increases as the diameter decreases. A selection of the bearing clearance in accordance with next table attenuates this tendency.

In case that axial thrust is subject to change direction or if shock in axial direction is to be expected (marine applications, fans, ), dimension b5 may be reduced by 0,2 mm for sizes up to 28 and by 0,3 mm for sizes 35 and 45. If type B or K or J axial bearing is only needed for a trial run, b5 may be larger. 3) If type Q bearing should allow shaft axial movement (caused by thermal expansion or due to a system-specificly large axial clerance), b7 may be larger. 4) No need to provide undercut if d is equal to or smaller than D. 5) Undercut according to DIN 509 may be provided instead of rounding radii r1. 6) For seal type 11, 12, 21 and 22 check info at seals table on forward pages of this catalogue.

16. SEALING SYSTEMS Seal Type 10 (IP44) Seal type 10 consists of a floating labyrinth seal tightened by a garter spring and supported by aluminium housing. Floating labyrinth seal is made of synthetic material reinforced with fibre, which presents outstanding long-term heat resistance properties. This type of seal has the capacity of absorbing shaft radial displacements due to its floating movement in the housing. Admissible negative pressure: 50 Pa Type 10 Available for bearing sizes 9 28 Seal Type 11 (IP54) Seal type 11 consists of a floating labyrinth seal type 10 combined with a dust flinger. The function of this flinger is protecting the bearing from dust but also protecting the labyrinth seal against any negative pressure. Dust flinger is clamped to the shaft so rotates with it, preventing any particle to ingress into the bearing. The correct alignment of dust flinger is important for proper performance. Admissible negative pressure: 250 Pa Type 11 Available for bearing sizes 9 28 Seal Type 12 (IP55) Seal type 12 consists of a floating labyrinth seal type 10 combined with a bolt-on baffle. The additional baffle protects the seal against dust and water jets. IP56 level can be achieved with this seal by inserting a V-ring between baffle and labyrinth seal. This sealing system is available upon request for special applications. Admissible negative pressure: 150 Pa Type 12 Available for bearing sizes 9 28 Seal Type 20 (IP44) Seal type 20 consists of two rigid labyrinth systems, made of aluminium alloy. This seal is intended for bearings with high oil throughput. For higher degree of protection seal type 20 can be combined with a dust flinger, forming seal type 21 (IP54), or with a bolt-on baffle, forming seal type 22 (IP55). IP56 level can be achieved with seal type 22 by placing a V-ring between baffle and labyrinth seal. This sealing system is available upon request for special applications. Type 20 admissible negative pressure: Pa Type 21 (rigid labyrinth seal + dust flinger): Pa Type 22 (rigid labyrinth seal + bolt-on baffle): 200 Pa Type 20 Available for bearing sizes 9 71 23
