Deep Groove Ball Bearings SKF 63005 -2RS1

The SKF 63005 -2RS1 deep groove ball bearing is protected against dirt by a ground seal on both sides and is designed for shafts with a diameter of 25 mm.

The 63005 -2RS1 deep groove ball bearing is a single-row radial ball bearing made from standard 100Cr6 rolling bearing steel, with a bore diameter of 25 mm, an outer diameter of 47 mm and a width of 16 mm. This SKF rolling bearing primarily absorbs radial forces and also supports axial loads in both directions. The design complies with the standard tolerance class P0 (PN) or ABEC 1 and features a dimensionally stable sheet steel cage to ensure the rolling elements are guided in an orderly manner.

What is the 63005-2RS1 deep groove ball bearing suitable for?

This size is primarily used in compact shaft mountings where combined radial and axial forces occur. Thanks to the sealing discs that make contact on both sides, the component is particularly suitable for working environments where moisture, splash water or fine particles may reach the bearing location. Once installed, the bearing requires no relubrication, as the interior is filled with grease at the factory and the seal contact retains the lubricant inside the bearing.

What is the function of the 2RS1 seal in this ball bearing?

The suffix -2RS1 denotes sealing discs made of synthetic rubber fitted on both sides, which rub against the inner ring with a contact lip. This design provides protection against the ingress of foreign particles and minimises grease leakage across the permissible temperature range of -20 to +120 degrees Celsius. The design, which incorporates standard radial bearing clearance, ensures that the necessary operating clearance is maintained during operation with standard fit selections, without unwanted bearing play causing vibrations.
