Product description

Information

DIN 808 universal joints with needle bearings are known for their precision. They have minimal play and are long lasting.

The allowable r.p.m. of these joints is higher than for those with friction bearings, but is still dependent on load, duration, angular disposition, and lubrication. Ideal applications allow speeds of up to 4000 r.p.m.

Needle bearings give the universal joints at 3° to 5° angular disposition a considerably higher degree of efficiency than those fitted with friction bearings. The needle bearings have permanent lubrication and thus do not require servicing.
