Track runner bearings are designed to run on all types of tracks and to be used in cam drives, conveyor systems, etc. These bearings have a thick-walled outer ring, which enables them to accommodate high radial loads, while reducing distortion and bending stresses.
The outer ring running surface is crowned as standard. This is beneficial for applications where angular misalignment relative to the track may occur or where edge stresses need to be minimized. With the exception of single row cam rollers, track runner bearings are also available with a cylindrical (flat) outer ring running surface.
SKF supplies track runner bearings greased, sealed and ready to mount.
SKF supplies track runner bearings in many different types and designs, and for a wide variety of operating conditions and applications. The assortment comprises:
Single Row Cam Rollers
SKF single row cam rollers are based on deep groove ball bearings in the 62 series. They are supplied greased and capped with a sheet steel reinforced NBR contact seal on both sides.
Double Row Cam Rollers
SKF double row cam rollers are based on double row angular contact ball bearings in the 32 dimension series and have a 30° contact angle. They are supplied greased and capped with either a sheet steel shield, on boths sides, that extends into a recess on the innner ring (suffix -2Z) or an RS contact seal on both sides (suffix -2RS1).
