Deep Groove Ball Bearings SKF 62303 -2RS1

The SKF 62303 -2RS1 deep groove ball bearing, measuring 17x47x19 mm, offers compact protection against dirt and moisture for a wide range of industrial applications.

The SKF 62303 -2RS1 deep groove ball bearing is a single-row radial ball bearing with seals on both sides. With a bore of 17 mm, an outside diameter of 47 mm and a special width of 19 mm, this design primarily accommodates radial loads. Thanks to its robust sheet steel cage and raceways made from standard rolling-element bearing steel (100Cr6), the component is equally suitable for demanding maintenance repairs and for long-term use in mechanical engineering.

For which operating conditions is the 62303-2RS1 deep groove ball bearing suitable?

This design is primarily used where dusty or damp environmental conditions prevail and additional installation space is available for wider bearings. Thanks to the 2RS1 contact seal on both sides, the lubricant remains inside the bearing whilst external particles are kept out. Design engineers and maintenance personnel specifically opt for this variant when durable assemblies are required without the need for external sealing measures.

What are the key features of the 2RS1 seal in this bearing?

The sliding seal protects the rolling elements from ingress of contaminants and moisture. Whilst open variants rely on external housing seals, the 62303 -2RS1 deep groove ball bearing is supplied sealed as standard. Please note the specified temperature range of -20 to +120 degrees Celsius. The standard radial bearing clearance and manufacture to tolerance class P0 (ABEC 1) ensure that the bearing can be fitted precisely onto standard shafts with a diameter of 17 mm.
