Needle Roller Cam Track Bearing
A cam roller carries motion directly against a shaped cam or straight running track. Unlike a conventional bearing installed inside a housing, its outer ring becomes the wheel that contacts the working surface.
Description
Product Details
The bearing uses needle rollers inside a thick outer ring. This construction keeps the radial section compact while allowing the outer ring to withstand repeated contact with a track.
Most of the working load should act toward the center of the roller. Side thrust caused by an incorrectly positioned guide, excessive skew or poor mounting should be kept to a minimum.
The track is part of the bearing system and requires attention during design. Its hardness, surface finish, joint transitions and alignment influence running noise and wear as much as the roller itself.
Product Description
Choose the bearing from the required roller diameter, roller width and mounting arrangement. A stud-mounted version is fixed through its threaded shank, while a bore-mounted version requires a separate shaft or bolt. These two mounting styles are not directly interchangeable.
A flat outer profile provides a larger contact area when the track is accurately aligned. A crowned profile is more tolerant of small angular errors but produces a narrower contact zone. The outer-ring profile must therefore be confirmed from the selected model or drawing.
Before powered operation, move the mechanism slowly through a complete cycle. Check that the roller remains fully supported, does not strike a track joint and is not forced sideways at either end of travel.

FAQ
Can this bearing run directly on a machine track?
Yes. The outer ring is the running element, but the track must have suitable hardness, finish and alignment.
Are all cam rollers mounted with a threaded stud?
No. Cam rollers are available in different mounting constructions. Confirm the actual model and drawing before preparing the mounting plate.
Can a cam roller carry continuous side load?
It is primarily selected for radial loading. Persistent side force usually indicates skew, incorrect guidance or an unsuitable installation.
Why should the track joint be checked?
A raised edge or gap can create repeated impact on the outer ring and shorten the service life of both the roller and the track.
Can a bearing be produced from a supplied drawing?
We build to customer drawings under OEM/ODM, and accept orders as small as a single piece for standard sizes.
