Guide Pulleys

ROTAFRIX® guide pulley

ROTAFRIX® guide pulleys made of solid rubber, optionally in combination with damping elements, are ideal for guiding hoisting cages and buckets. Continental has developed a special version which meets the durability requirements even at high conveying speeds of up to 20 m/s (72 km/h). The result is high-performance elements which are of simple construction, low-noise and maintenance-free. They are used for hoisting systems in mines.

ROTAFRIX® guide pulleys consist of a contact face, a base layer and a strength member.

Contact Face

The properties of the surface layer are matched to the special requirements imposed on it. A choice of two abrasion-resistant compounds is therefore available:


  • Natural rubber basis
  • Hardness 67 Shore A
  • Suitable for speeds up to 14 m/s (50 km/h)


  • Natural rubber basis
  • Hardness 67 Shore A
  • Suitable for speeds up to 20 m/s (72 km/h)

Base Layer

The base layer consists of a special hard elastomer material. It is firmly bonded to the contact face by means of vulcanization and contains the strength member. The base layer is manufactured for both cylindrical and tapered hub finishes.

Strength Member

The strength member keeps the guide pulley under constant tension and ensures a particularly firm fit on the hub. In the FM finish the strength member consists of steel reinforcing wires, and in the FMH finish the strength member is a steel ring.
Guide pulleys are sold without the hub.
