Deep Groove Ball Bearings SKF 6012 -2Z

The SKF 6012-2Z deep-groove ball bearing is a single-row rolling bearing with a 60 mm bore, a 95 mm outer diameter and cover plates on both sides.

With the 6012-2Z deep groove ball bearing, you are choosing a versatile rolling bearing made from standard bearing steel (100Cr6). This design is primarily designed to accommodate radial loads as well as moderate axial forces in both directions. With key dimensions of 60 mm inner diameter, 95 mm outer diameter and 18 mm width, this design is suitable for a wide variety of shaft mountings in mechanical and plant engineering. As an SKF Explorer variant, the bearing is characterised by a precision-machined internal geometry.

What is the 6012-2Z deep groove ball bearing suitable for in practice?

This bearing is particularly recommended for rotating shaft guides where protection against dirt particles is required without additional friction losses. The design is suitable for compact bearing arrangements operating at medium to high speeds. The non-contacting cover plates made of sheet steel shield the rolling elements from external particles, whilst the integrated sheet steel cage maintains an even spacing between the balls. This keeps rotational resistance low and ensures that heat generation during operation remains moderate.

What are the distinctive features of the design with cover plates and tolerance class P6?

The designation -2Z indicates cover plates fitted on both sides, which form a narrow sealing gap with the inner ring. As no sliding contact occurs, this variant allows for high speeds whilst providing protection against foreign particles. Tolerance class P6 (comparable to ABEC 3) ensures greater running accuracy and tighter dimensional tolerances compared with standard tolerance. Combined with standard radial bearing clearance and a temperature range of -20 to +120 degrees, the bearing is suitable for precision-guided industrial applications.
