This tapered roller bearing carries the radial and axial loads transmitted through the kingpin assembly of the front axle. It sits between the steering knuckle and the axle beam, allowing the knuckle to pivot while maintaining alignment under the weight of the tractor. A worn bearing produces free play in the steering, leading to imprecise directional control and accelerated tire wear. This original AGCO component is machined to the same internal geometry as the factory bearing, so it seats against the kingpin shoulder and the housing bore without requiring shimming. On installation, clean the housing bore and apply grease to the roller cage before pressing the bearing into place.
