Deep Groove Ball Bearings SKF 6012 -2RS1

The SKF 6012-2RS1 deep groove ball bearing offers protection against contact on both sides and P6 running accuracy, with main dimensions of 60 × 95 × 18 mm.

As a single-row radial ball bearing, the 6012 -2RS1 is one of the most commonly used rolling bearings in mechanical engineering. With a bore of 60 mm, an outside diameter of 95 mm and a width of 18 mm, this rolling bearing accommodates radial forces as well as axial loads in both directions. The SKF Explorer design features an optimised internal geometry, whilst the sheet steel cage guides the rolling elements, made from standard rolling-bearing steel (100Cr6), during operation.

Under what operating conditions is the 6012-2RS1 deep groove ball bearing used?

Designs with rotating shafts tend to favour this bearing unit for combined load requirements. As the bearing is designed for a temperature range of -20 to +120 degrees, it covers typical conditions in industrial environments. The double-sided seal protects the bearing interior from the ingress of dust, moisture or dirt particles. At the same time, the lubricant remains inside the bearing, which reduces maintenance requirements during operation.

What features do the 2RS1 seal and tolerance class P6 offer?

The factory-fitted, double-sided sliding seal discs (2RS1) make an elastic contact with the inner ring shoulder and form a barrier against environmental influences. In addition, tolerance class P6 (or ABEC 3) offers tighter manufacturing tolerances in terms of dimensional and concentricity accuracy compared with the standard tolerance. In combination with the standard radial bearing clearance, this design is suitable for bearing arrangements where low-noise and low-vibration operation is a priority.
