This Tapered Roller Wheel Bearing # 68149 is designed to fit trailers that use 5 Lug, 3,500lb Hubs. The trailer spindle that this wheel bearing would be used with is commonly referred to as a #84 Spindle. This Bearing Size is typically used as an Inner Bearing (the bearing installed near the Grease Seal), but not all 5 Bolt hubs will use this particular bearing. For example, a 2,200lb Capacity Trailer Hub may have 5 lugs, but would use 2 smaller bearings than this 68149 with a 1 3/8" inner diameter. 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
