Double Row Spherical Roller Bearings

Double-row spherical-roller bearings are non-demountable. They are manufactured in multiple series.

Double-row spherical-roller bearings are manufactured either with cylindrical or conical opening, the taper ratio of which is either 1:12 or 1:30.
The bearings are fitted straight onto the conical pintle of the shaft or, by means of an adapter sleeve or tightening bushing, onto a cylindrical pintle.
Double-row spherical-roller bearings have two rows of spherical rollers with a common spherical track on the outer ring. This allows tilting of the inner bearing ring towards the outer ring around the centre of the bearing, without affecting its correct function. These bearings are capable of compensating abaxiality, shaft deflection and even element malformation.

These bearings can transmit high radial and simultaneously acting axial loads in both directions.

Double-row spherical-roller bearings have high rigidity. The bearings are supplied with standard radial clearance, bearings for special placing applications can be supplied either with lower or higher radial clearance. The bearings are manufactured in normal accuracy class, seating demanding higher accuracy or higher rpm frequency utilize bearings with higher running accuracy – P6.
