Support rollers(Yoke type track rollers) have an internal design based on needle or cylindrical roller bearings. They have a thick-walled outer ring, which enables them to accommodate high radial loads, while reducing distortion and bending stresses.

The outer ring running surface is crowned as standard. However, support rollers with a cylindrical (flat) running surface are also available.


The support roller (roller follower) is used in a wide range of applications such as cam mechanisms of automatic machines, dedicated machines as well as carrier systems, conveyors, bookbinding machines, tool changers of machining centers, pallet changers, automatic coating machines, and sliding forks of automatic warehouses.

The cam follower is  pre-greased, ready-to-mount units are suitable for all types of cam drives, tracks and conveyor systems.

Application of C&H cam followers:

  1. Escalator;
  2. Moving sidewalk;
  3. Elevator;
  4. Conveyor system;
  5. Lifting machinery;
  6. Automotive line machinery;
  7. Material handling equipments;
  8. Linear motion guidance equipments;
  9. Cam drives;
  10. Screw drives;

Advantages of C&H Cam followers:

  1. Optimized structure and reliable quality;
  2. Modifying the contacting surface logarithmically to reduce the contact stress;
  3. Full ranges of precision standards for different working conditions;
  4. saving the mounting and maintaining costs with ready-to-fit units;
  5. prolonging the working lifespan by filling grease for life;
