Features:

Premium Quality：These ball bearings are made of premium 304 stainless steel material to ensure that they are strong, non-deforming, rust-proof and corrosion-resistant. They still maintain their initial performance even under humid condition for a long time. Polish finished for a smooth and glossy surface.

Functions：The low friction coefficient of these ball bearings allows the machines to rotate with minimal resistance, reducing energy loss and extending their lifespan.

Wide Application：The steel ball bearings can be widely used in bicycles wheel, auto parts, bearings, casters, drawer slides, DIY projects, door locks, and a variety of small machinery applications, including skateboard wheels, inline skates, and electric motors, instrumentation and more.
