Track rollers

By contrast with other roller bearings, the outer ring of track rollers runs directly on a mating track. The mating track – rails, guide rail, cam disc – can be straight or curved. The outer ring replacing the housing is designed in these components to be very strong for that reason so that it can absorb tensions and deflections. To avoid any edge pressures arising from frequent tilting of the outer ring against the mating track, the coat of the outer ring is predominantly spherical or designed with a specific spherical profile. Track rollers differ in the rolling elements used and the configuration of the inner ring. There are many designs. In particular, the increasing demands of automation lead to a constant development of track rollers in respect of effectiveness and performance capability..
