Deep Groove Ball Bearings SKF 6202 -2Z

The SKF 6202-2Z deep groove ball bearing features compact dimensions of 15 × 35 × 11 mm, sheet metal shields on both sides and fine P6/P5 tolerances for demanding shaft mountings.

The 6202-2Z deep groove ball bearing is a single-row rolling bearing made from standard 100Cr6 bearing steel with non-contacting cover plates on both sides. As an SKF Explorer variant, this design combines a compact construction with tight manufacturing tolerances. This design primarily accommodates radial forces as well as moderate axial loads in both directions. The design features a cylindrical outer ring without a flange or groove and is rated for operating temperatures from –20 to +120 degrees Celsius.

For which operating conditions is the 6202-2Z deep groove ball bearing designed?

This radial ball bearing is used in rotating shaft assemblies where low-noise concentricity and low friction are paramount. Its applications include compact bearing arrangements subject to moderate loads and continuous rotational movement. Thanks to the combination of dimensional accuracy to tolerance class P6 and running accuracy to P5, the component ensures low-vibration rotation of the shaft. The robust sheet steel cage maintains the rolling elements at a uniform distance at medium to high speeds.

What is the function of the end shields and P6/P5 tolerances in the 6202-2Z?

The end shields on both sides, marked -2Z, protect the interior from coarse foreign particles without generating additional frictional heat through sliding contact. When designing the bearing seat and shaft, the P6/P5 accuracy facilitates the selection of a precise fit, as tighter manufacturing tolerances more reliably limit the radial and axial bearing clearance once the bearing is installed. When designed with standard radial bearing clearance, the bearing arrangement requires precisely machined bearing seats to prevent stress build-up during operation.
