Cylindrical Roller Bearings from Koyo and JTEKT North America
Cylindrical roller bearings are characterized by high radial-, and moderate thrust-load capacities. They contain cylindrically-shaped roller, which are nevertheless not true cylinders. Instead, they are crowned or end-relieved to reduce stress concentrations. This particular geometry results in low friction and allows high-speed appliions.
Transient Dynamic Analysis of High-Speed Lightly Loaded
The mainshaft bearings used for high speed turbines are both cylindrical roller and ball bearings. The bearings have both high radial load capacity and the ability to permit rela- tively unconstrained axial motion under differential thermal expan- sion of the rotor when the engine is at operating condition.
