Taperlock tension bushings are the standardized, commercially available machine parts for creating non-positive shaft-to-hub connections with a pulley. The conically slotted bushing with feather key groove according to DIN 6885 serves to fasten pulleys to shafts or journals.

 

Taperlock tension bushings are available in different outside dimensions. A large number of bore sizes are available for each outside dimension, i.e. for the corresponding shaft diameter. The 4-digit number refers to the outside dimension, the 2-digit number indicates the bore size.
