Deep Groove Ball Bearings SKF 6006 -2RS1/C3

The SKF deep groove ball bearing 6006 -2RS1/C3 (30x55x13 mm) combines contact seals on both sides with increased C3 radial clearance for industrial applications subject to thermal stress.

With the SKF 6006 -2RS1/C3 deep groove ball bearing, users benefit from a single-row radial ball bearing in the Explorer performance class for a wide range of industrial applications. The component has a bore of 30 mm, an outside diameter of 55 mm and a width of 13 mm. The rings and rolling elements are made of case-hardened 100Cr6 bearing steel. A robust sheet steel cage guides the balls evenly into the deep raceways. This design is suitable for combined radial and axial loads at operating temperatures ranging from –20 to +120 degrees.

In which operating environments does the 6006-2RS1/C3 deep-groove ball bearing prove its worth?

This roller bearing is primarily used in rotating shaft mountings that combine continuous rotational speeds with elevated thermal conditions or tight fits. Typical applications include drive units and machine components subject to combined radial and axial forces. Thanks to the sealing rings that rub against both sides, the grease filling remains inside the bearing, whilst dust particles and moisture are kept away from the raceways.

What do the C3 bearing clearance and tolerance class P6 mean?

The designation C3 indicates a slightly increased radial bearing clearance compared with the standard version. This increased clearance compensates for heat-induced expansion of the shaft or housing during operation without the bearing becoming stressed. The tolerance class P6 (comparable to ABEC 3) also denotes tighter manufacturing tolerances in terms of running accuracy and dimensions. During design, it is advisable to adapt the fits and temperature conditions to the increased operating clearance.
