Spherical Roller Bearings

Spherical roller bearings are self-aligning bearings designed for heavy radial loading. They automatically compensate for large angular errors (shaft misalignments). They are usually of the double row design, both the rows of the rollers having common spherical raceways in the outer ring. This feature of this bearing has great practical importance in those cases where it is difficult to obtain exact parallelism between the shaft and housing both axes. So these bearings are suitable where misalignment can arise from mounting errors or from deflection of the shaft. They have the ability to take static as well as dynamic misalignment. Spherical roller bearings are particularly suitable for carrying heavy loads. They are commonly found in Industrial Gear boxes, Conveyors, Cement Grinding Rolls, Sugarcane crushers and passenger coach axle boxes of Railways.

Spherical Roller

Spherical Roller Thrust

Spherical roller bearings are self-aligning bearings designed for heavy radial loading. The rollers are barrel shaped. These bearings automatically compensate for large angular errors commonly called shaft misalignments. They are usually of double row design, both the rows of the rollers having common spherical raceways in the outer ring. This feature has great practical importance in those cases where it is difficult to obtain exact parallelism between the shaft and housing both axes.

Spherical roller bearings are commonly found in Industrial Gear boxes, Conveyors, Cement Grinding Rolls, Sugarcane crushers and passenger coach axle boxes of Railways.

Spherical roller thrust bearings can accommodate heavy axial load, they are adapted to high speeds. These bearings are fitted with asymmetrical barrel shaped roller.

Under normal load conditions, the allowable misalignment is 1˚ to 2˚, although this will vary depending upon the bearing’s dimension series. These bearings use machined copper alloy cages and a guide sleeve is attached to the inner ring to guide the cage. The axial load capacity of these bearings is high, and a certain amount of radial load can also be accommodated when the ring is in an axially loaded state.
