Wheel Bearing Protectors / Bearing Buddy

Wheel Bearing Protectors / Bearing Buddy

Trailer axle hub & drum wheel bearing protectors replace original equipment dust caps to allow for adding bearing grease to the wheel hub to maintain proper lubrication and provide corrosion protection. Wheel bearing protectors use a spring piston to automatically maintain the correct internal grease pressure that will not damage grease seals.

Bearing protector caps keep road dirt out, and grease splatter in.  Maintain the integrity of wheel bearing protectors by always using a 'bra' cover.
