DIN 808 Universal Joint, Needle Bearing.
These universal joints with needle bearing have a high level of precision. They have minimal play and are long lasting.
The permissible r.p.m. of these joints is higher than for those with friction bearings, but is still dependent on the load, duration of use as well as angular disposition. 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 a permanent lubrication and thus do not require servicing.
Steel - blank.
Joint bearing areas, pins, bearing sleeves - case hardened.
