4x13x5 Ball Bearing – 4 mm ID, 13 mm OD, 5 mm Thickness

The 4x13x5 ball bearing is a precision mechanical component designed to reduce rotational friction and support radial loads in compact mechanical systems. It features a 4 mm inner diameter, 13 mm outer diameter, and 5 mm thickness, making it suitable for small-scale applications requiring smooth and stable motion. Manufactured with hardened steel races and rolling elements, it ensures consistent performance and durability under continuous operation. This bearing is ideal for robotics, electric motors, 3D printers, and general mechanical assemblies.
