KOYO 67780/67720D+L double row tapered roller bearings



TDO series bearing is composed of a double row cup, two single row cones and an inner ring spacer. It has oil groove and oil holes on the outer ring, which is convenient from external to internal bearing lubrication. In order to get the right clearance, it adjusts the bearing inner ring spacer to achieve proper pre-load. It may also needn’t adjust the spacer and use any adjustment method for installation but the operation is more troublesome, it’s especially suitable for moment occasions such as reducer or hoist.
