Jefa washers with a ball track

The Jefa washers with a ball track are used in combination with a locking ring to provide a smooth and light running vertical locking system.
The washer with balls replaces the standard delrin ring which acts as a gliding bearing and is normally positioned between the top bearing and locking ring above. 
The washer with balls is made of delrin and the balls are also made of delrin.
The maximum working load varies depending of the diameter from 100 to 300 Kg.
