BALL BEARING Russian patent published in 2016 - IPC F16C11/06 

FIELD: machine building.

SUBSTANCE: invention can be used as supports of sliding in fasteners, capable of retaining its operability in wide range of loads both in air, and in high vacuum. Ball bearing comprises housing made of two covers (1, 2) rigidly connected to each other, with enclosed in casing ball pin (3) with spherical head located in insert (4). Ball pin (3) is made from material PVL-16, and on its surface there is multilayer composite coating (7) with shear resistance lower than shear resistance of ball bearing, first substrate layer by galvanic coating is made of tantalum, second layer of silver is applied electrolytically, and third - solid-lubricant VAP coating.

EFFECT: higher wear resistance of ball bearing, providing a positive voltage gradient, as well as ability for recovery of damages to antifriction layer.
