This Tapered Roller Bearing # 14125A is designed to fit 7,000 - 8,000 lb trailer axles that use 8 Lug Hubs. This Bearing Size is typically used as an Outer Bearing (the bearing installed near the spindle nut where the dust cap is installed), but not all 8 Lug hubs will use this particular bearing. 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. The Inner diameter of this wheel bearing measures 1 1/4 inches, which would be the same measurement as the surface of the spindle this bearing fits on. The 8 bolt spindle this wheel bearing most commonly is used with is the #42 Spindle.
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.
