Description
1. Product Overview

The 21311E is double row E-type optimized high-capacity spherical roller bearing with straight cylindrical bore, standard dimension 55×120×29mm. Suffix E stands for upgraded internal geometry without inner ring center rib, fitted with longer crowned rollers and two stamped steel cages, boosting dynamic load capacity by 20%~30% vs standard series. Spherical outer raceway delivers strong self-aligning performance to offset shaft deflection and assembly misalignment, withstands heavy combined radial load, bidirectional axial thrust and frequent impact shocks. Outer ring built-in lubriion groove & holes support periodic regreasing, widely used in mining crushers, cement mixers, belt conveyors, heavy gearboxes and construction rotary equipment.
