SKF Double Row Yoke Type Track Rollers Cam rollers are ball bearings which have a particularly thick-walled outer ring
They are ready-to-mount pre-greased units and are used for all types of cam drives, conveyor systems etc
The 3058 series with a crowned runner surface should always be used where angular misalignments with respect to the track may be expected and edge stress should be kept to a minimum
These wide cam rollers have been developed with a 30° contact angle
They are fitted with sheet steel shields which extend into recesses in the inner ring side to keep the lubricant in and contamination out
