DIN 808 universal joints with friction bearings are known for their precision. They have minimal play and are long lasting.  
The allowable r.p.m. of these joints is largely dependent on the type of application, including load, duration, angular disposition, and lubrication. For r.p.m.s over 1000, universal joints with needle bearing should be used.  
For continuous use ample lubrication is essential. This can be achieved by fitting the joint with a grease-filled bellow GN 808.1.  
GN 808.1 Bellows, without grease, available upon request.  
Square bore available upon request.  
Inch size bores larger than listed available upon request.  
See determining the size of DIN 808-FB universal joints.
See assembly directions.

See our technical section for bore, keyway (DIN 6885/1 JS9) and square details.
