2 2 Orion Euro Style Bearings About Orion Corporation Orion Corporation is a leading designer and manufacturer of hydrodynamic bearings for rotating machinery. Products include a complete line of Euro Style pivoting shoe thrust bearings, tilting pad journal bearings, equalizing and non-equalizing tilting pad thrust bearings, and flat and tapered-land thrust plates. Our experienced, skilled engineering group will work with you to develop the right solution for your application. For more than 50 years, we have designed and built bearings for turbines, turbochargers, compressors, expanders, gear drives, electric motors, generators, pumps, diesel locomotives and other equipment for industrial, utility and marine applications. Orion s primary manufacturing plant, along with corporate, sales and engineering offices are located in Grafton, Wisconsin, USA. A second plant is located in Columbus, Nebraska, USA. Quality certifications Quality Management Systems are certified to ISO 9001:2000 standards by Lloyd s Register Quality Assurance, LTD. This includes accreditation by the National Accreditation Council (Great Britain), Dutch Council of Certification and DAR Accreditation (Germany). All critical operations in bearing manufacture, including centrifugal casting, machining, assembly and inspection are performed at our facilities. Euro Style Bearings Orion Corporation, a leader in the manufacture of tilting pad journal and self-leveling tilting pad thrust bearings, now offers a complete line of Euro Style pivoting shoe thrust bearings. This design is interchangeable with European-type thrust bearings, and is ideal for new or retrofit applications. Bearing description The Euro Style features the Orion spray nozzle lubrication system. This proven technology offers spray nozzle feed between pads, which improves oil flow. It also improves oil film thickness, while lowering lube oil frictional loss and oil film temperatures. The result is improved performance and increased dependability. The Euro Style bearings are designed to rotate in either a clockwise or counter-clockwise direction, minimizing the number of spares required. Carrier rings are constructed in halves to facilitate easy installation in applications where access is difficult. Lubrication ports from the bearing ring deliver oil to the sprays and then into the bearing pads. The pad body is standardly constructed of low carbon steel with a high tin content babbitt face. Variations in material selection are available for special applications. Orion s spherical pivot allows the pad to pivot to the most desirable angle for optimal film generation, without the edge-loading problem common on line contact pivots. This pivot design also allows for more uniform temperature distribution on the pad. The pad pivot on the back of the pad is hardened to 48 to 52 Rockwell C to prevent flattening of the sphere.

3 3 The retaining ring is manufactured from low carbon steel with tensile of 480 MPA. A retaining fastener, similar to those used in most European-type bearings, holds pads in place.
