The KNOTT 410250.001 Waterproof Compact Bearing Kit is a professional hub repair kit for KNOTT trailer axles. This waterproof version is designed for use in demanding conditions, particularly on boat trailers, flatbed trailers, and utility trailers exposed to water, moisture, sand, and road salt.

A bearing dedicated to KNOTT axles with a gross vehicle weight (GVW) of 1350 kg and 1500 kg . Commonly used in branded boat trailers, flatbed trailers, and high-quality cargo trailers.

The kit includes a double-row compact angular contact bearing measuring 34 x 64 x 37 mm.
