22213 EK Spherical Roller Bearing 65x120x31mm Tapered Bore 1:12 Self-aligning

1. Product Overview

22213 EK is double row metric spherical roller bearing, dimension 65×120×31mm. EK stands for 1:12 tapered inner bore, matched with adapter sleeve H313 for easy installation and disassembly. Outer ring with lubrication groove and holes for convenient relubrication. Spherical roller structure compensates shaft misalignment and deflection, bears heavy combined radial and bidirectional axial loads. Widely used in mining crushers, belt conveyors, large industrial fans, cement machinery and heavy reducers.
