Deep Groove Ball Bearings SKF 6215 -2RS1

The SKF 6215-2RS1 deep groove ball bearing has a 75 mm bore, an outer diameter of 130 mm and is protected against contamination by a ground seal on both sides.

The 6215-2RS1 deep groove ball bearing is a single-row rolling bearing designed primarily for radial loads, but it also accommodates axial loads in both directions. SKF manufactures the rings and rolling elements from standard 100Cr6 bearing steel and fits the bearing with a sheet steel cage. The seals, which seal on both sides, retain the grease within the system and repel solid contaminants and moisture. With the standardised tolerance class P0/PN or ABEC 1, the bearing fits precisely into standard machine designs.

What loads and mounting conditions can the 6215-2RS1 deep groove ball bearing accommodate?

This radial ball bearing is used wherever shafts with a diameter of 75 mm need to be supported and combined radial and axial forces need to be accommodated. The bearing is designed for a temperature range of –20 to +120 degrees, thereby meeting the thermal requirements of common industrial operating environments. As the cylindrical outer ring has no groove or flange, the component can be press-fitted directly into flat housing bores.

What is the function of the 2RS1 seal variant during operation?

The 2RS1 design features two sealing discs in contact with one another, whose sealing lips rest against the rotating inner ring under slight contact pressure. This design protects the rolling elements and raceways from the ingress of dust, dirt particles or moisture. Thanks to the factory-applied grease fill, the bearing operates with minimal maintenance over long periods, as no grease needs to be replenished. When designing the application, it should be noted that, due to friction, sliding contact seals allow for lower speeds compared to open bearings.
