Spherical Roller Bearing
Rowiss spherical roller bearings are designed to manage high radial loads even when misalignment, poor lubrication, contamination, extreme speeds or critical application stresses are present. Spherical bearings consist of an inner ring, outer ring, cage and center-rounded rollers. FEATURES OF SPHERICAL ROLLER BEARINGS There are two basic spherical roller bearing designs. R & RR type uses two sets of convex asymmetrical rollers separated by a center inner ring rib. The RH, RHR, and RHA design uses two rows of longer symmetrical rollers and only a center guide ring instead of a rib. The bearing is self-aligning and forgiving to errors of up to 1.5° of misalignment between the shaft and housing due to shaft bending. Spherical bearings can carry radial and axial load in both directions. Suitable for applications where there is heavy radial and impact loading applied. The bearing can be manufactured with a cylindrical or taper bore. The taper bore bearing is easily mounted with the use of an adaptor sleeve. Lubrication grooves and holes can be provided on either the inner or outer rings. Cage types can be pressed steel, machined copper alloy.
