For use with Bearing Buddy on Trailers with brakes or as replacement seals. Before SPINDO SEAL, a trailer with brakes and/or poor quality axle sealing surfaces could not be fitted with rear seals which would prevent grease leakage because rough sealing surfaces would quickly destroy any seal. Now, with SPINDO SEAL, permanently smooth, corrosion proof axle sealing surfaces together with high quality neoprene seals provide a system which allows the seal to ride on a smooth sealing surface constantly greased by the action of the Bearing Buddy. Seals will last many years with only negligible grease leakage.
