Yoke truck rollers are designed to perform on all types of outer wheels used in thick cam drives, conveyor systems, while bending to reduce distortion and while these bearings allow high radial loads.
The outer wheel running surface can be crown as standard. This is beneficial for applications where a relative angle deviation may occur against the track or where edge stress is minimized. Yoke truck rollers are also available on cylindrical (flat) outer wheel driving surfaces, except for a single row of camrollers.
