Cam Rollers - Designs and Variants
Single row cam rollers
Single-row cam rollers are derived from deep groove ball bearings in the 62 series. They feature a thick-walled outer ring with a crowned running surface and are sealed with NBR contact seals on both sides, reinforced by sheet steel.
Double row cam rollers
Double-row cam rollers are based on double-row angular contact ball bearings from the 32-dimension series. They have a thick-walled outer ring with either a crowned or cylindrical running surface. These cam rollers feature a 30° contact angle that supports tilting moments and come in two capped variants: one with a sheet steel shield (-2Z) and the other with an NBR contact seal (-2RS1).

Frequently Asked Questions (FAQs)
Q: What are cam rollers?
A: Cam rollers are a rolling bearing specifically designed for applications requiring linear motion or guided movement. They feature a thick-walled outer ring that can withstand high radial loads and provide smooth motion along tracks or guides.
Q: What is the difference between single-row and double-row cam rollers?
A: Single-row cam rollers are based on deep groove ball bearings and are ideal for light to medium loads, providing a compact solution. Double-row cam rollers are based on angular contact ball bearings, offering greater load capacity and the ability to handle tilting moments, making them more suitable for heavier loads and demanding applications.
Q:What are the main applications for cam rollers?
A: Cam rollers are used in various applications, including conveyor systems, cam drives, material handling equipment, and automotive manufacturing. They are ideal for environments requiring smooth, guided movement under heavy loads.
Q: What are the available surface designs for cam rollers?
A: Cam rollers have two types of running surfaces: crowned (curved) and cylindrical (flat). Crowned surfaces are standard and help reduce edge stresses in track-guided applications, while cylindrical surfaces provide more contact area for better load distribution.
Q: How are cam rollers lubricated?
A: Most cam rollers are pre-greased for life and require no relubrication under normal operating conditions. However, if the rollers are subjected to high temperatures, moisture, or contaminants, they may require relubrication through designated lubrication holes in the inner ring.
Q: Can cam rollers operate at high speeds?
A: Yes, cam rollers can operate at high speeds, but it’s essential to ensure they are properly lubricated. In some cases, grease leakage may occur under very high-speed conditions. Preventive actions, such as shields or seals, can help protect the cam roller in such environments.
Q: What should be done if grease leaks from cam rollers during operation?
A: Grease may leak from the cam roller in high-speed or high-temperature conditions. If this happens in applications where leakage could be detrimental, consider adjusting the operating conditions or implementing additional seals to prevent contamination.
Q: What are the common materials used in cam rollers?
A: Cam rollers are typically made from high-grade steel for strength and durability under heavy loads. Stainless steel cam rollers are sometimes used for applications that require resistance to corrosion, such as in food processing or marine environments.
Q: How do I choose between a shielded or sealed cam roller?
A: Shielded cam rollers (designation suffix -2Z) are better for applications where protection against large particles is needed. Sealed cam rollers (designation suffix -2RS1) offer better protection against moisture and fine contaminants, making them suitable for more challenging environments.
