Deep Groove Ball Bearings SKF 6315 -2RS1

The SKF 6315-2RS1 deep groove ball bearing, with a 75 mm bore and a ground seal on both sides, provides protection against contamination in industrial shaft mountings.

This single-row deep-groove ball bearing 6315 -2RS1 from SKF is suitable for designs in which predominantly radial loads occur. Thanks to the deep raceway geometry, the unit also accommodates axial forces in both directions. The Explorer-grade version is made from standard rolling-element bearing steel (100Cr6) and features a dimensionally stable sheet steel cage. With an outer diameter of 160 mm and a width of 37 mm, this component is well-suited to medium to heavy-duty shaft support applications in mechanical engineering.

What is the 6315-2RS1 deep groove ball bearing suitable for in operation?

Design engineers prefer to use this size for rotating shafts subjected to combined loads. The bearing guides the shafts precisely and ensures low-vibration operation. As the outer ring is cylindrical with no groove or flange, the assembly can be fitted directly into suitably machined housing bores. The permissible temperature range extends from –20 to +120 degrees Celsius, enabling the component to be used in a wide range of applications in continuous industrial operation.

What are the advantages of the 2RS1 seal in this rolling bearing?

The suffix 2RS1 denotes abiding seals fitted on both sides. The elastic sealing lips rest against the inner ring and keep moisture and abrasive particles out of the bearing interior. At the same time, the lubricant remains within the bearing chamber. Thanks to the standard radial bearing clearance, the operating clearance is optimised for typical fits and operating temperatures. This simplifies the design of suitable fits for the shaft and housing.
