SKF
Track Rollers
SKF track rollers — encompassing cam followers (stud-type track rollers), support rollers (yoke-type track rollers), and cam rollers (yoke-type based on ball bearings) — are specialized rolling bearings designed to run on all types of tracks and function in cam drives, conveyor systems, material handling equipment, and linear guidance applications. These bearings feature thick-walled outer rings with crowned or cylindrical running surfaces that withstand high radial loads while minimizing edge stresses and bending deformation. SKF cam followers incorporate needle or cylindrical roller bearings with a threaded solid stud (instead of an inner ring) for easy mounting. Support rollers use a yoke-type design with an inner ring and mounting hole. Cam rollers employ ball bearings for higher-speed, lower-load applications. All SKF track rollers are supplied sealed and ready-to-mount, pre-greased for immediate installation. For design engineers specifying material handling systems, packaging machinery, automation equipment, and custom cam-driven mechanisms, SKF track rollers deliver the durability and precision essential for reliable, long-running track-based motion.

Thick-Walled Outer Rings for Maximum Load Capacity
The heavy-section outer ring resists distortion and bending stresses under high radial loads, while the crowned running surface (standard on most types) accommodates minor misalignment with the track.
Three Product Types Cover Every Track Application
Cam followers (stud-type) for easy threaded mounting, support rollers (yoke-type) for two-sided support, and cam rollers (ball bearing-based) for higher speeds and moderate loads.
Sealed & Ready-to-Mount Design
All SKF track rollers are factory-greased and fitted with integral seals that retain lubricant and exclude contamination, arriving ready for immediate installation without additional preparation.
Needle & Cylindrical Roller Options
Choose needle roller-based track rollers for compact dimensions and high load capacity, or cylindrical roller-based designs for applications demanding maximum robustness and speed capability.
Integral Relubrication Features on Selected Models
Certain SKF track roller designs include grease fittings or lubrication holes, enabling in-service relubrication for extended maintenance intervals in demanding applications.
Standardized Mounting Dimensions
SKF track rollers conform to industry-standard stud diameters, thread sizes, and mounting dimensions, ensuring interchangeability with competing designs and simplifying replacement.
Cam Followers vs. Support Rollers: Selection Guide
The choice between cam followers (stud-type) and support rollers (yoke-type) depends on the mounting configuration and load support requirements. Cam followers mount by threading the integral stud directly into a tapped hole or through a clearance hole with a retaining nut. This single-point mounting is ideal for applications where the track roller functions as a cantilevered element, such as in cam-actuated mechanisms, linear motion carriages, and conveyor side guides. Support rollers (yoke-type) mount via a bolt or pin through the bearing bore and are typically supported on both sides, providing greater stability and load capacity. They excel in fork-style mountings, conveyor roller supports, and applications with width constraints that prevent nut attachment on the stud side. Both types are available with needle roller or cylindrical roller internals, and both offer crowned or cylindrical outer ring running surfaces.
Industries and Applications for SKF Track Rollers
SKF track rollers serve diverse industrial applications where rolling elements must travel along tracks, rails, or cam surfaces. In material handling systems, track rollers support and guide conveyor belts, accumulating conveyors, and sortation systems. Packaging machinery uses cam followers in sealing, cutting, and folding mechanisms that require precise, repeatable motion. Automation and robotics applications employ track rollers for linear guidance and cam-driven pick-and-place mechanisms. The automotive industry uses track rollers in assembly line fixtures, welding positioners, and paint shop conveyors. Heavy industries including steel processing, paper converting, and textile manufacturing all depend on SKF track roller technology for reliable, low-maintenance linear and cam-driven motion.
