These steel bearings have a black coating to help them resist wear longer. They are made for the industry standard 608 bearing bore in wheels. Our bearings feature a Removable Rubber Shield that allows for easy maintenance, greatly reduced friction, and has none of the annoying rattling noise from regular metal shields.

We got away from metal retainers and chose High Speed Nylon Ball Retainers which generate less friction, allow you to maintain your forward momentum better and also rids our bearings from the annoying rattling noises of metal retainers. Another great advantage of Nylon retainers is that we have one less piece of metal to rust.

The Ninja Bearings come packed with our PRO Ultimate + Speed Lubricant, which means that your bearings will be race ready out of the box.

Comes in a box with a set of 16 bearings
