The 6203 bearing is a single-row deep groove ball bearing manufactured by our company in Sweden. It corresponds to the new model 6203 and the old model 203 in China and belongs to the 60000 bearing category.

This bearing has an inner diameter of 17 mm, an outer diameter of 40 mm, and a thickness of 12 mm. Made of stainless steel and featuring a sealless, open design, it can operate with either oil or grease lubrication. It is primarily used in industrial applications such as construction machinery, machine tools, and the automotive industry.

This bearing has a basic dynamic load rating of 10 kN and a static load rating of 4.8 kN. It has a maximum speed of 24,000 rpm and a reference speed of 38,000 rpm.

Its structure, consisting of a ring, cage, and ball assembly, can withstand radial and limited axial loads, allowing axial displacement within the clearance range and a tilt angle of no more than 8-16 inches.

Weighing approximately 0.065 kg, it is widely used in AC welding machines, cleaning machinery, and the plastics industry.

The primary difference between 6203 2RS and 6203 bearings lies in their sealing method:
