LYC self-aligning ball bearing has a sphere raceway in the outer ring and a double-raceway in the inner ring. This feature gives the bearings the self-aligning property which can keep the machine operating well even when angular misalignment of the shaft relative to the housing happens. Values of permissible misalignment errors of double row self-aligning ball bearings are given in the section “selection of bearing type”.

Self-aligning ball bearing is mainly used to carry radial loads and light axial loads but they cant carry pure axial loads.

 

Basic Structure

Self-aligning ball bearings of LYC standard design are available with a cylindrical bore and with a taper bore (taper 1:12). Self-aligning ball bearings can be directly located on the taper journal with lock nut and can also be mounted on the cylindrical shaft with suitable adaptor or withdrawal sleeve. The internal radial clearance of bearings can be adjusted by adaptor sleeve.

LYC can provide other structures of self-aligning ball bearings for customers such as sealed self-aligning bearing self-aligning  ball bearing with extended inner ring etc. All types cant be listed in this catalogue. If customers need please consult LYC technical department. 

LYC can also design self-aligning ball bearings with special structures according to customers requirement.

 

Cages

LYC self-aligning ball bearings are supplied with a pressed steel cage a machined solid cage or glass fiber reinforced polyimide 66 and brass solid cage.
