ROLLER BEARING TAPERED, NO.30217

This design utilizes conical rollers and raceways arranged so that all elements of the roller & raceway cones meet at a common apex on the axis of rotation. The roller is guided by contact between the large end of the roller and a rib on the inner rings. This construction provides high capacity for radial loads & single direction thrust loads. The bearings are usually mounted in pairs with axial adjustment to provide proper running clearance within the bearings. Being separable, the inner and outer rings may be mounted individually. For heavy thrust loads the type 30300D with large contact angle is preferable. Series 30200
