Deep Groove Ball Bearings SKF 6215 -RS1

The SKF 6215-RS1 single-row deep groove ball bearing, measuring 75 × 130 × 25 mm and featuring a single-sided RS1 seal, offers effective protection against contamination whilst allowing for flexible relubrication.

The 6215-RS1 deep groove ball bearing is a single-row radial ball bearing from SKF designed for shaft diameters of 75 mm. It primarily accommodates radial forces and supports shafts under axial loads in both directions. Manufactured from standard rolling-element bearing steel 100Cr6, the component complies with tolerance class P0/PN (ABEC 1). A sheet steel cage guides the rolling elements within the permissible temperature range of –20 to +120 degrees Celsius.

What is the 6215-RS1 deep groove ball bearing suitable for in mechanical engineering?

Design engineers and maintenance technicians use this bearing size in industrial drives and rotating shaft mountings subject to combined radial and axial forces. With an outer diameter of 130 mm and a width of 25 mm, the component absorbs radial loads. As the outer ring has no flange or groove, it fits precisely into cylindrical housing bores. The sheet steel cage retains lubricant on the rolling elements and helps maintain consistent rotational speeds.

What are the key features of the single-sided RS1 seal?

The RS1 design features a sealing lip that seals on one side, whilst the other end remains open. This design shields the raceways from dust and moisture on the outer side. At the same time, the open side allows lubricant to enter via the interior of the housing, for example in the case of oil bath lubrication. With normal radial bearing clearance, this design is suitable for standard fits at moderate operating temperatures.
