22216 E Spherical Roller Bearing 80x140x33mm Cylindrical Bore Self-aligning Heavy Load Bearing

1. Product Overview

22216 E is double row metric spherical roller bearing with cylindrical straight bore, dimension 80×140×33mm. E optimized reinforced roller structure improves load capacity and anti-fatigue performance. Outer ring equipped with annular lubrication groove and oil holes for convenient supplementary lubrication. Spherical raceway design effectively compensates shaft deflection and installation misalignment, bears heavy combined radial and bidirectional axial loads. Widely applied in mining crushers, industrial centrifugal fans, belt conveyors, cement machinery and heavy-duty gear reducers.
