Note:
1.The rotational speed limit value in the table applies to models with grease lubrication. With models using oil lubrication, up to 130% of this value is permitted.
2.The sealed type is provided with prepacked grease. The shield type is not provided with prepacked grease. Perform proper lubrication for use.
3.We also supply stainless steel, the material is available with AISI440C or AISI420C ( DIN 1.4306, 9Cr18Mo) 
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. These 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;
