Timken 6,000 lb Trailer Hub Bearing Kit 25580 (1 3/4" ID) x 15123 (1 1/4" ID) with 2 1/4" ID Grease Seal

This is a 6,000 lb Trailer Hub Bearing Kit featuring all Timken / National Grease Seal components, providing the best bearings, seals, and races that money can buy for your Trailer. While most Bearing / Seal brands on the market are perfectly safe and effective at what they do, Timken brand products go above and beyond to offer the absolute best in craftsmanship, engineering, and performance to minimize the likelihood of Grease Seal issues caused by manufacturing defects or premature failure. 

This Kit features a 25580 1 3/4 inch inner diameter tapered trailer roller bearing along with its matching 25520 Trailer Bearing Race, and a 15123 1 1/4 inch inner diameter trailer bearing with the matching 15245 trailer bearing cup race. This kit is designed for 6,000 lb trailer hubs and axles with #42 spindles that use the 15123 outer bearing, so make sure that you are getting the correct bearing kit as some trailers will use different outer bearings. The kit also features a Double Lipped Grease Seal which has an inner diameter of 2 1/4", and an Outer Diameter of 3.376". We've also included a replacement 1 inch spindle tang washer and cotter pin to make your trailer bearing replacement even easier! This kit can be used with 6k (commonly 6 lug) idler hubs, brake drum hubs, or integral disc brake hub / rotors; the bearing combination is frequently used on 6 lug trailer hubs and rotors made by Dexter, Kodiak, Lippert, Rockwell, and others.
