Timken 12S42500 is a commercial vehicle standard wheel seal. It keeps lubricant sealed in the wheel end and keeps dirt and other contaminants out, which protects the bearings behind it from early wear. A heavy double-walled metal outer shell grips the hub bore so the seal resists spinning or working its way out, and the sturdy outer wall helps carry heat away from the sealing lip. Vented, corrosion-proof spacers let lubricant flow to the lip, and several nitrile contact points on the lip act as barriers against contamination. A genuine Timken part from Pro Gear and Transmission.
