Front Hub Bearing for GY6 50cc Scooters
This front hub bearing is made for 50cc scooters that use the GY6 139QMB engine. It helps your scooter steer more predictably and stay safer on the road. If the wheel wobbles or makes odd noises, swapping in this bearing can noticeably smooth out your ride. It's one of the useful GY6 50cc scooter parts that keeps the wheel turning with low friction, supporting a steadier feel at the front end.
Precision Engineering
This bearing measures 30mm across the outside and 10mm across the inside, so it sits snugly in the front hub of your scooter. Two shields guard the inner races against dirt and moisture, which helps it last longer. It runs at high speed and works with both 10-inch and 12-inch wheels for everyday city riding.
Installation Considerations
If you replace one wheel bearing, consider replacing the other at the same time so the wheel rolls evenly on both sides. Use a bearing driver tool to seat it without damaging the race. Clean the hub cavity well, then add a thin layer of high-temperature grease for the best results.
