Product Overview
A cam follower bearing is a shaft-type bearing with needle rollers assembled between a thick-walled outer ring and an inner ring, making it ideal for use on guide rails for conveying.
A cam follower is a high-performance shaft-type bearing with needle-shaped rollers, known as needle rollers, assembled inside. The needle rollers enhance rotational capability and can withstand high-speed rotation. In addition, the outer ring features a thicker wall design compared to standard bearings, making it suitable for applications subject to impact loads or heavy loads.

Product Features
1. With shaft, easy to install!
2. Ideal for load-bearing applications!
3. Also suitable for high-speed rotation!
Standard Cam Follower Structure
Roller Guidance Method
Cam followers with cages are suitable for applications requiring low friction and high speed, while full complement cam followers are suitable for high-speed rotation and heavy load applications.
Seal structure
In non-sealed bearings, the gap between the outer ring and the end rod circumferential area, as well as between the outer ring and the side plate, is small, forming a labyrinth. In sealed bearings, a sealing gasket is installed in the shielded labyrinth section to prevent foreign matter from entering.
Outer ring outer diameter shape
Bearings with a spherical outer ring can alleviate uneven loads caused by installation issues. Bearings with an arc-shaped outer ring have a larger contact area with the guide rail, making them suitable for applications with heavy loads or guide rails with low hardness.

Precautions
· If the cam follower drops to the ground or is struck with force, it may be damaged.
· When subjected to impact, even if there is no visible damage, functionality may still be impaired. Please take note.
· Cam followers are suitable for radial loads and are not well suited for thrust loads. Therefore, please avoid using them in applications that apply thrust loads.
