Handling Procedure for Correct Mounting of RKB Bearings in WOR Configuration - 1

BEARING INDUSTRIES HANDLING PROCEDURE FOR CORRECT MOUNTING Bearing design In order to accommodate higher values of misalignment, in RKB spherical roller bearings WOR configuration the outer ring is redesigned and optimized in order to have an increased outer ring width. In addition, some series of WOR bearings feature two separate outer raceways connected with a clamping ring that facilitates mounting and dismounting. Integral outer ring Outer ring in two halves Mounting procedure Before starting the assembling operation, check if the outer diameter of the clamping ring is smaller than the outer diameter of the outer rings. If such a condition is verified, the bearing can be assembled directly on the shaft/housing as a normal design, without removing the clamping ring. On the contrary, if the outer diameter of the clamping ring is larger than the outer diameter of the outer rings, please remove the clamping ring prior to assembling in order to avoid damaging it (see picture 1 Executive Headquarters and Technological Center P.O.

In this latter case, the correct sequence to mount the bearing is shown below: i) Remove the clamping ring; ii) Separate the two outer rings; iii) Insert first outer ring in the housing; iv) Insert the inner assembly (inner ring, cage and rollers), already preassembled on the shaft, into the first outer ring (see point above); v) Insert the second outer ring; vi) Bring outer rings into contact and make sure they are correctly abutting each other and are duly blocked in order to get a monolithic outer ring.
