Universal joints with friction bearing DIN 808 are known for their precision. They have minimal play and are long lasting.

The permissible r.p.m. of universal joints with friction bearing is to a large extent dependent on the type of application such as load, duration, angular disposition as well as lubrication. For over 1000 r.p.m. universal joints with needle bearing should be used.

For continuous use ample lubrication is essential. This achieved by fitting the joint with a grease filled gaiter GN 808.1.

On the official DIN standard sheet is d₁ = 20 (instead of 22) and 40 (instead of 42). Furthermore DIN provides for sizes d₁ = 63, 75 and 90, however, sizes d₁ = 28, 36, 45 and 58 mm are missing.

The above order example refers to universal joints with equal bores both ends d₂ and s. As specials, universal joints can also be supplied with unequal bores.
