with

The invention relates to mechanical engineering, in particular to the production of polymer antifriction materials and products from them, and can be used to create highly loaded sliding bearing bearings in various fields of technology: transport engineering, aircraft and shipbuilding, light and food engineering.

The purpose of the invention is to increase the load capacity and operational reliability of an anti-friction product. ,

Fig. 1 shows an anti-friction product; in Fig.2-node I in Fig.1.

The anti-friction product consists of a support base 1 made of injection-molded high-strength plastic, which is a binder, and rigidly bonded with it a two-layer woven

frame 2, including an antifriction layer 3, consisting of polytetrafluoroethylene filaments, and a carrier layer 4, consisting of organic filaments, and placed in a recess formed by the support base 1 and the edge annular ribs 5, having a height equal to the thickness of the two-layer woven frame 2, and made integrally with the supporting base 1. Example. An antifriction product with a support base made of injection molded polyformaldehyde of the PF-L-10 brand (TU 6-06-14-90) with a two-layer woven frame made of LTSVMPF-an-39-m tape (TU 17-09-14-259- 88), with an outer diameter of 44 mm, an inner diameter of 38 mm and a length of 54 mm, used in the suspension of a heavy transport vehicle instead of an antifriction sleeve with periodic lubrication.
