Deep Groove Ball Bearings SKF 6302 -2Z

The SKF 6302-2Z deep-groove ball bearing, measuring 15 × 42 × 13 mm, features sheet metal shields on both sides for protected high-speed applications.

The SKF 6302-2Z deep groove ball bearing is a single-row rolling bearing made from standard 100Cr6 bearing steel, designed for combined radial and axial loads. With a bore of 15 mm, an outside diameter of 42 mm and a width of 13 mm, its geometry complies with common industry standards. The integrated sheet steel cage reliably guides the rolling elements whilst maintaining a low weight. The SKF Explorer design is characterised by an optimised internal geometry and refined raceway surfaces.

In which applications is the 6302-2Z deep-groove ball bearing used?

This single-row ball bearing is primarily used in rotating systems where radial forces predominate and moderate axial forces in both directions need to be supported. Typical applications include bearings in general mechanical engineering involving continuous rotational movement. Thanks to the non-contacting sheet metal cover plates, the component is suitable for applications involving higher speeds, as no additional frictional heat is generated in the sealing gap. The permissible temperature range is from –20 to +120 degrees Celsius.

What are the advantages of the -2Z cover plates and the standard clearance design?

The double-sided cover with metal cover plates (designation -2Z) protects the bearing interior from coarse dirt particles and reduces the risk of grease leakage. As the plates do not come into contact with the rotating inner ring, the frictional torque remains minimal. The standard radial bearing clearance ensures low-vibration operation with typical fit selections and moderate operating temperatures. In environments with fine dust or splashing water, designers should alternatively consider contact seals.
