This engineering specification allows for better thermal expansion during use, reducing friction and keeping your wheels spinning smooth and true. They are built to resist corrosion and water damage much better than generic alternatives, making them ideal for the unpredictable UK weather.

🔧 Install Tips

Freeze Before Fit: Freeze the new bearings for 1–2 hours before fitting. This makes them slightly smaller and significantly easier to press into the wheel hub.
Use a Driver: Use a proper bearing driver tool or a large socket to tap them in evenly. Never hammer the inner race, as this may damage the seal and internal components.
Lubricate Hub: Apply a light smear of grease or anti-seize to the aluminum bearing seats to prevent seizing during future removal.
Torque Check: Do not overtighten the axle bolts or you could cause internal binding. Spin the wheel after fitting to ensure smooth, quiet movement.
