Information

Fork joints GN 751 consist of a fork head according DIN 71752 and a pin with KL-shaft (Type KL and SL) a pin with snap-on spring (Type B). Both versions can be dismantled without tools and moniter. 
Size d1 = 12 is supplied with a fine thread M12x1.5 according to DIN. In practice, however, M12x1.25 is preferred. Standard DIN 71752 does not foresee size d1 = 20. 

On request

Fork heads in accordance with DIN 71752 with d1 = 25, 30, 35, 42 and 50 (only Steel Version) 

Technical information

Types of fork joint shafts

The snap-on spring pin is easily mounted and dismantled. It is therefore particularly suitable for applications where the articulated connection needs to be loosened often.

The pin with side mount ring can be fitted and dismantled without tools, i. e. by hand.

The pin with safety clip requires a tool for dismantling (e.g. a screw driver). It is therefore better secured.
