Help keep the pinion or idler shaft turning smoothly under load with the Schaeffler KHM89449 Differential Pinion Bearing. This tapered roller bearing cone is also listed as a transfer case idler shaft bearing. It is a direct-fit replacement for many vehicles, including the 1967-1972 and 1978-1981 Chevrolet Camaro and the 1964-1972 Chevrolet Chevelle. See the "Vehicles it fits" section for the full list of applications.
In a differential, a pinion bearing supports the rotating pinion shaft as it drives the ring gear. In a transfer case, this bearing supports the idler shaft. As a cone, KHM89449 is the inner ring and roller assembly of a tapered roller bearing. The matching cup (outer race) is a separate part. Schaeffler builds more than 100 million tapered roller bearings each year.
