This Tapered Roller Bearing # 44643 is designed to fit trailers that use 4 or 5 Lug Hubs on either 2,000lb or 2200lb trailer axles. This Bearing Size is typically used as both an Inner Bearing (the bearing installed near the Grease Seal) and an outer bearing (The bearing installed near the Flat Washer), on a straight 1 inch spindle. Not all 4 or 5 Bolt hubs will use this particular bearing, however. Because of this, it's always best to check the Bearing Numbers and Measurements in your Trailer Hub Prior to ordering so you know you're getting the correct parts to fix your Trailer.
Boat and Utility Trailers both need to service and maintain their Bearings regularly, which often includes replacing the bearings to make sure everything runs smoothly. The number one way to maintain your bearings is to make sure they are always properly lubricated with High Quality Trailer Wheel Bearing Grease. We offer a few of the industry's best brands of Trailer Bearing Grease, including Marine Grade Grease for Boat and other Watercraft Trailers. You can find our selection of Greases at this link here
