Marine Axle Seals and Boat Trailer Tips
This video shows you how to grease and install a trailer-bearing seal correctly. Steve explains the step-by-step procedure to install new bearing seals and beat water ingress. Marine Bearing kits offer a marine seal as opposed to a standard seal.
What is the difference between a marine and a standard seal?
- A highway seal is affixed to the inside of the hub and spins with the hub
- Whereas, a marine seal is affixed to the axle and does not spin
- In addition, a marine-bearing seal utilises a stainless steel outer ring to enable the rubber seal to spin.
How to install a marine seal summary
- Tap the outer stainless ring into the rear bearing boss.
- Smear a little marine silicon on the axle seal surface.
- Apply a liberal amount of grease into the seal lips to reduce friction drag.
- Insert seal onto the axle journal that is smeared with silicon.
- Finally, insert the hub or disc rotor into position and lock it with the axle nut.
