44643 Replacement Trailer Bearing 1" ID for 2,000 - 2,200lb Trailers

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.
