Good bearings, slow delivery

The bearings themselves are excellent and fit perfectly in my scooter wheels. Only giving 4 stars because shipping took longer than expected.

High speed performance

Using these for a high RPM application. They handle the speed well without overheating. Great value for imported Japanese bearings.

Smooth operation for skateboards

Installed these on my longboard and the difference is night and day. Very smooth roll and no noise even at high speeds. Genuine NSK quality.

Perfect for kids scooters

Bought these to replace worn out bearings on my kids' scooters. They spin freely and seem very durable. Highly recommend.
