Applications & Features:
--- Suitable for all kinds of industrial equipment, motor, skateboards, roller wheels, office equipment and so on.
--- Deep Groove Ball Bearings are one of the most widely used rolling bearings. They are used to accommodate radial and axial loads in both directions (Mainly bear radial load, but also can bear a certain amount of axial load).
--- The bearings are made of carbon steel, which has durability and resistance to rust, corrosion and deformation under heavy load.
--- With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance.

Useful Tips:
--- Please refer to the picture and select the right type of bearings before your order (Sealed or Shield on BOTH or SINGLE side of the bearing). Suffix on the bearing just for differentiating between the Sealed and Shield type of bearing. It would not affect the use of our product.
