Wire Rope Sheaves

Quick Ref: CN-1898
Wire Rope Sheaves

Pfaff wire rope pulleys with sheave diameters from 80mm to 490mm and rope diameters from 6mm to 18mm.

The sheaves DSR made of steel provides a safe concept due to a wear-resistant rope guide where the machine groove is perfectly adjusted to the wire rope. There are 15 different types guarantees that are at a made-to-specification solution at loads of up to 8 tons. The sheaves can be varied in wire and sheave diameter (from 80 up to 490 mm) and as standard all sheaves are equipped with ball bearings.
