It is a highly crystalline polymer with a smooth glossy surface: wear-resistant, resistant to oxidation and staining, self-lubricating and oil-tight. It is characterized by high strength and dimensional stability.
The metal parts of the ball bearings are made of Cr40 alloy steel with obligatory hardening . The special technology of mirror processing ensures that the surface roughness of the ball pin is no more than 0.4 microns, which significantly increases the service life of the hinge. The design and processing technology of the ball joint ensure that even with large angular loads, the ball joint will not jump out of its regular seat.
