Hydraulic lift keeps big bearings lubed at low speeds. • Large bearings need help to generate a lubricating oil film at low speeds. • Pockets in journal and thrust bearings supplied with ...

For full-film lubrication of journal and thrust bearings, is typically above the range of 3 to 10. Misalignment, thermal, and elastic distortions can raise that to about 10 to 20.

The bearings were refurbished using MD&A’s proven methods and final bore machining was completed after as machined journal dimensions were determined. In addition to bearing repair, 8 journals ...
