Deep Groove Ball Bearings SKF 6313 /VA201

The SKF 6313/VA201 deep groove ball bearing, measuring 65x140x33 mm, provides heat-resistant support for demanding industrial environments up to +250 degrees.

This single-row deep-groove ball bearing 6313 /VA201 is designed as an open bearing and is manufactured by SKF. Fitted with a sheet steel cage and a special grease, the component covers a temperature range from –40 to +250 degrees. It is manufactured to tolerance class P0/PN or ABEC 1. Thanks to its design without a flange or groove on the outer ring, the rolling bearing can be fitted directly into cylindrical housing bores.

In which temperature ranges is the 6313 /VA201 deep groove ball bearing used?

This deep-groove ball bearing is designed for applications with high operating temperatures up to +250 degrees. The design is suitable for applications where rolling bearings are exposed to continuous heat. The open design allows for direct heat dissipation during operation, whilst the integrated special grease maintains lubrication under sustained thermal loads. The single-row raceway geometry primarily absorbs radial forces.

Why are the rings and rolling elements manganese-phosphated?

Both the bearing rings and the rolling elements are manganese-phosphated. This chemical surface treatment provides protection against corrosion and improves the running-in behaviour of the rolling elements. In conjunction with the significantly increased radial clearance, the bearing compensates for operational thermal expansion of the shaft. This helps to prevent the rolling elements from seizing at high operating temperatures and supports consistent concentricity during extreme temperature fluctuations.
