ANTIFRICTION BEARING Russian patent published in 2012 - IPC F16C27/06 F16C19/52 F16C33/62 

FIELD: machine building.

SUBSTANCE: proposed device is made up of butted antifriction bearings (two or three) with their outer and/or inner racers faced by solid of composite bushing made from structural polymer material with modulus of elasticity of 300-15000 MPa, for example, polyethylene, polyamide, fiber glass. Facing serves to compensate for differences in sizes of butted bearings. Composite bushings may feature different length and be made from structural polymer materials with different modulus of elasticity.

EFFECT: increased bearing capacity, expanded performances.
