Bearing Wholesalers develop and build a range of trailer bearing kits suited to all trailer applications. Bearing Wholesalers make multiple versions of trailer bearing kits to suit any desired application such as marine trailer bearing kits for boat and jet ski trailers which are often exposed to salt water. Trailer bearings are essential to trailers, allowing the wheels to rotate without unnecessary friction or resistance. Reducing friction in the trailer hub and wheel assembly increases fuel economy when towing a trailer and ensures the trailer can follow freely at required speeds.
