Type 11.213:
The core of this pulley type is the design of the sliding fit. A coated hub in the form of a four-sided polygon with pulley flanges of diecast aluminium is used nowadays in the compact units.
Type 11.101:
Power range 0.37 - 18.5 kW at n1=1500 RPM. The tensioning needed for power transmission is exerted in this type by pulley springs centrally installed on both sides of the pulley flanges.
Type 11.104:
Power range 0.37 - 3 kW at n1=1500 RPM. The tension required to transmit power is exerted here by cylindrical pressure springs rotationally symmetrically installed on both sides of the pulley flanges. The variable speed pulleys are life-lubricated and maintenance-free.
