Product Description

Spherical roller bearings are of non-separable construction. They are manufactured in multiple series.

Double-row spherical-roller bearings are manufactured either with cylindrical or tapered bore, the taper ratio of which is normally 1:12. However, for series 240 and 241, the taper is 1:30. The bearings having a cylindrical bore are fitted straight onto a cylindrical shaft, whereas a bearing having tapered bore is to be mounted either on a shaft having same taper as in the bore of the bearing, or on a straight shaft by means of an adapter sleeve or a withdrawal sleeve, inserted between the shaft and the bearing. Double row spherical roller bearings have two rows of spherical rollers with a common spherical track on the outer ring bore. This allows swivelling of the bearing inner ring with respect to the outer ring around the centre of the bearing, without affecting its correct function. Thus, these bearings are capable of compensating misalignment, shaft deflection and even machining error in the machine components to a certain extent.

 

These bearings can transmit high radial and axial loads in either direction simultaneously.

 

Double row spherical roller bearings have high load carrying ability. The bearings are supplied with standard radial clearance. However, bearings for special applications can be supplied either with lower or higher radial clearance. The bearings are manufactured in normal accuracy class, However, bearings with higher running accuracy can also be supplied.
