RADIAL-AXIAL SLIDING BEARING Russian patent published in 2015 - IPC F16C17/10 

FIELD: machine building.

SUBSTANCE: proposed bearing comprises a sleeve from antifriction material with outer cylindrical mounting surface and working surfaces. The working surface for taking up a two-sided axial load is made in the form of several annular grooves with a triangular equilateral profile. The sleeve can be of split type and can have the possibility of mounting a counterbody on annular grooves. The surface of the annular groove is coated by self-lubricating material. A polymer composition based on epoxy resin 1 wt. p. and filling agent in the form of fluoroplast powders 0.10-0.15 wt. p. and graphite 0.05-0.08 wt. p. is used as self-lubricating material.

EFFECT: increasing durability of an axial radial bearing due to the prevention of uneven wearing out of working surfaces at a sleeve, especially at the operation of friction units with dynamic loads and temperature drops.
