The wheel bearing seal is a critical sealing component that protects the wheel bearing against moisture, dirt, and salt. It sits on the inside of the wheel hub and seals the space between hub and axle to keep bearing grease in place. Fits ALKO and GSM brake systems on your trailer, caravan, boat trailer, car transporter, and horse trailer.

Always replace the wheel bearing seal when dismounting the wheel hub — dimension 30x52x7 mm. This extends wheel bearing service life and prevents bearing grease from leaking. VALERYD's wheel bearing seals are available for most brands and sizes.
