2 Features Integrated Check Valves Helps extend seal life Self-Lubricating Bushing Lengthened Spool Valve Lands Higher-efficiency operation More Rigid Components Helps reduce internal leakage Shaft Seal Withstand high back pressures Corrosion Protected Resist corrosion in hosile environments Extends seal life, decreasing the fluid pressure acting on the shaft seal and reducing case pressure to return pressure by as much as 0% of full system pressure. Case drain option is recommended for some series applications (see page 1). Reduces shaft friction under radial side loads to ensure adequate lubrication and support under all rated conditions. Reduces internal leakage into the motor case resulting in improved efficiencies and increased shaft turns per liter/gallon. Resists deformation and subsequent leaks at higher pressures using more rigid components such as the wear plate. Time proven shaft seal design and construction allow motors to withstand high back pressures without an external case drain. The motors can be connected together in series, or parallel to one another, see page for more infomation. motors are available with a corrosion resistant coating for use in an hostile environment. Such as salt, water, and various chemicals. It is especially effective in marine, food processing, car wash, fishing, and agricultural applications. Shaft plating helps eliminate seal damage caused by these caustic or acid materials in the shaft sealing area. Corrosion protected motors are available with just the output shaft plated, or protected with an entire motor exterior coating.

3 General Purpose Spool Valve Hydraulic Motors from One of the World s Leading Manufacturers of Off Highway Mobile Components Eaton Corporation Char-Lynn motors provide a lot of power from a very small package, indeed, up to kw [ 1/ HP] of power. These motors are 1 millimeters [. inches] in diameter and to millimeters [.1 to.1 inches] in length. motors are the smallest of Eaton's line of Char-Lynn motors. These motors have high starting and running torque, and operate with equal torque in either direction. With this new :1 Geroler element, the five rollers provide support with rolling contact as the Geroler four lobe star rotates, minimizing friction and providing high efficiencies especially at start-up and at low speeds.

These compact motors have an hydrodynamic output shaft bearing. This hydrodynamic shaft bearing will accept high radial shaft loads, as well as high thrust loads common on sprocket and chain, or pulley and belt drive applications. The new bushing design reduces friction even further. The motor shaft seal allows a high case pressure of up to Bar [00 PSI] return line pressure without case drain line. When a case drain line is used a 0 Bar [ PSI] peak pressure is allowed in the return line. These small motors can be mounted in any orientation that would suit the application. The driving device, sprocket, pulley, etc., can be mounted directly onto the motor shaft.

Hydraulic lines bringing pressurized fluid from the pump to the motor and return flow from the motor back to tank can be flexible or ridged. One pump can be sized to supply a single motor or many motors. Furthermore, one pump and multiple motors can be connected in series or in parallel (see each type of connection shown below). When connecting the pump to the motors in series excess internal case pressure is created in the motor, this excess pressure must be ported back to tank. However, when making a parallel connection from the pump to the motors no excess case pressure will be added. Hence, using the case drain ports are not necessary. Meanwhile, take a look at the application and see if this optional case drain port can be connected to your advantage, whether it be a single motor to pump connection, multiple motors connected to pump in parallel, as well as multiple motors connected to pump in series......case Drain Advantage In addition to providing lower case pressures for motors connected in series, there are advantages for adding an external case drain line to motors with normal case pressures as well. These advantages are: Contamination Control flushing the motor case. Cooler System exiting oil draws motor heat away. Extend Motor Seal Life maintain low case pressure with a preset restriction installed in the case drain line (see page 1) Motors ordered with case drain port will be shipped with steel hex socket plug installed in that end cap drain port. Case Drain Optional Parallel Connection Series Connection

13 Shaft Side Load Capacity The hydrodynamic bearing has infinite life when shaft load ratings are not exceeded. Hence, the shaft side load capacity is more than adequate to handle most externally applied loads (such as belts, chains, etc.), providing the motor to shaft size is applied within its torque rating. Allowable side load chart, shaft load location drawing (right) and load curves (below) are based on the side or radial loads being applied to shaft at locations A, B, and C, to determine the shaft side load capacity at locations other than those shown use the formula (shown below). For more information about shaft side loads on Char-Lynn motors contact your Eaton representative. 1 [] 1 [0] [1] Shaft Side Load kg [lb] [00] [00] [00] [0] A B C Sideload P kg = Sideload P [lb] = 00 N 00 N Where N = Shaft Speed (RPM) ( 00 L + ) ( 00 ) L + [1.] L = Distance from Mounting Surface Allowable Side Load kg [lb] RPM A B C 00 [ ] [ ] 0 [ ] 00 [ ] [ ] 0 [ ] 0 [1] [ ] [ ] 00 [1] [] [ ] 0 [1] [1] 0 [] 00 1 [] [0] [1] 00 1 [] 1 [] 0 [1] 00 1 [] 1 [0] [] 0 1 [] 1 [0] [1] C P B L A, [1.] 0,1 [.], [.] Speed (RPM) Mounting Surface Case Pressure and Case Drain The now offers check valves in the motor as a standard feature. This addition reduces the case pressure in the motor to the return pressure of the system when the case drain is not used. For return pressures higher than the rated pressures (see chart) the external case drain can be connected. If the case drain line is needed, connect drain line to assure that the motor will always remain full of fluid. P 1 Case Drain Advantage In addition to providing lower case pressures for motors connected in series, there are advantages for adding an external case drain line to motors with normal case pressures as well. These advantages are: Contamination Control flushing the motor case. Motor Cooler exiting oil draws motor heat away. Extend Motor Seal Life maintain low case pressure with a preset restriction installed in the case drain line. Pc P motors can be connected in parallel or in series. See Text page. * Case pressure will add to the allowable compressive thrust load. Case pressure will push outward on the shaft at 0 kg/ Bar [ lb/0 PSI]. Example: [Example:] Thrust Load Axial Loads kg [0 lb]* A 1 Bar case pressure will cause a load of 0 kg, so the allowable thrust load will be kg plus 0 = 0 kg pushing inward on shaft. Tension load is kg under all case pressure conditions. A 00 PSI case pressure will cause a load of lbs, so the allowable thrust load will be 0 lbs plus = lbs pushing inward on shaft. Tension load is 0 lb under all case pressure conditions.

14 Fluid Recommendations Introduction The ability of Eaton hydraulic components to provide the desired performance and life expectancy depends largely on the fluid used. The purpose of this section is to provide readers with the knowledge required to select the appropriate fluids for use in systems that employ Eaton hydraulic components. One of the most important characteristic to consider when choosing a fluid to be used in a hydraulic system is viscosity. Viscosity choice is always a compromise; the fluid must be thin enough to flow easily but thick enough to seal and maintain a lubricating film between bearing and sealing surfaces. Viscosity requirements, see chart below. Viscosity and Temperature Fluid temperature affects viscosity. In general, as the fluid warms it gets thinner and its viscosity decreases. The opposite is true when fluid cools. When choosing a fluid, it is important to consider the start-up and operating temperatures of the hydraulic system. Generally, the fluid is thick when the hydraulic system is started. With movement, the fluid warms to a point where a cooling system begins to operate. From then on, the fluid is maintained at the temperature for which the hydraulic system was designed. In actual applications this sequence varies; hydraulic systems are used in many environments from very cold to very hot. Cooling systems also vary from very elaborate to very simple, so ambient temperature may affect operating temperature. Equipment manufacturers who use Eaton hydraulic components in their products should anticipate temperature in their designs and make the appropriate fluid recommendations to their customers. Cleanliness Cleanliness of the fluid in a hydraulic system is extremely important. Eaton recommends that the fluid used in its hydraulic components be maintained at ISO Cleanliness Code /1 per SAE J. This code allows a maximum of 00 particles per milliliter greater than µm and a maximum of 0 particles per milliliter greater than µm. Cleanliness requirements for specific products are given in the table below. OEM s and distributors who use Eaton hydraulic components in their products should provide for these requirements in their designs. A reputable filter supplier can supply filter information. Fluid Maintenance Maintaining correct fluid viscosity and cleanliness level is essential for all hydraulic systems. Since Eaton hydraulic components are used in a wide variety of applications it is impossible for Eaton to publish a fluid maintenance schedule that would cover every situation. Field testing and monitoring are the only ways to get accurate measurements of system cleanliness. OEM s and distributors who use Eaton hydraulic components should test and establish fluid maintenance schedules for their products. These maintenance schedules should be designed to meet the viscosity and cleanliness requirements laid out in this document. Fluid Selection Premium grade petroleum based hydraulic fluids will provide the best performance in Eaton hydraulic components. These fluids typically contain additives that are beneficial to hydraulic systems. Eaton recommends fluids that contain anti-wear agents, rust inhibitors, anti-foaming agents, and oxidation inhibitors. Premium grade petroleum based hydraulic fluids carry an ISO VG rating. SAE grade crankcase oils may be used in systems that employ Eaton hydraulic components, but it should be noted that these oils may not contain all of the recommended additives. This means using crankcase oils may increase fluid maintenance requirements. Hydraulic fluids that contain V.I. (viscosity index) improvers, sometimes called multi-viscosity oils, may be used in systems that employ Eaton hydraulic components. These V.I. improved fluids are known to shear-down with use. This means that their actual viscosity drops below the rated value. Fluid maintenance must be increased if V.I. improved fluids are used. Automotive automatic transmission fluids contain V.I. improvers. Synthetic fluids may be used in Eaton hydraulic components. A reputable fluid supplier can provide information on synthetic fluids. Review applications that require the use of synthetic fluids with your Eaton representative. Product Line Viscosity Minimum 0 SUS 1 cst Best Range 0-00 SUS 0- cst ISO Cleanliness Requirements /1 Additional Notes: Fluids too thick to flow in cold weather start-ups will cause pump cavitation and possible damage. Motor cavitation is not a problem during cold start-ups. When choosing a hydraulic fluid, all the components in the system must be considered and the best viscosity range adjusted accordingly. For example, when a medium duty piston pump is combined with a Geroler motor the best viscosity range becomes 0-0 SUS [0 - cst] and viscosity should never fall below 0 SUS [1 cst]. If the natural color of the fluid has become black it is possible that an overheating problem exists. If the fluid becomes milky a water contamination problem may exist. Take fluid level reading when the system is cold. Contact your Eaton representative if you have specific questions about the fluid requirements of Eaton hydraulic components. 1
