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.
Please note: The threaded section of miniature cam follower bearings is of a small diameter.
To prevent damage, do not exceed the maximum tightening torque when installing with a wrench.
(The maximum tightening torque is approximately one-fourth that of a standard bolt. Please be aware of this.)

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.

Example of Use
Direction of movement
Installation Method
When installing, do not strike the flange of the cam bearing directly with a hammer, as this may cause poor rotation or breakage. Please use a hex wrench or a flathead screwdriver.
Secure the hex socket or screwdriver slot, then use a wrench to tighten the nut.
