Overview

Spherical roller bearing with tapered bore and relubrication features

Spherical roller bearings can accommodate heavy loads in both directions. They are self-aligning and accommodate misalignment and shaft deflections, with virtually no increase in friction or temperature. The design includes features to facilitate relubrication. The bearings can be used in a modular system, including housings, sleeves and nuts.

Key features

Accommodate misalignment
High load carrying capacity
Relubrication features
Low friction and long service life
Increased wear resistance

Typical applications

Conveyor pulleys
Crushers, screens, and mining equipment
Steel and paper machinery
Wind turbines and heavy machinery
