Support Rollers

Support rollers, also known as track rollers or cam followers, are specialized needle roller bearing assemblies designed to run on tracks, guides, or cam surfaces. They feature a thick-walled outer ring that serves as the running surface, with internal needle rollers providing high radial load capacity in a compact cross-section. These units typically include integral seals to retain lubrication and exclude contaminants in demanding operating environments.

When selecting support rollers, the designation indicates the bore diameter and design series—for example, NA22 series denotes yoke-type track rollers with different bore sizes denoted by the final digits. Choose based on bore diameter, radial load rating, and seal configuration (2RS indicates double rubber seals). Common applications include conveyor systems, material handling equipment, cam mechanisms, and linear motion systems where guided rolling contact is required.
