Deep Groove Ball Bearings SKF 6012 /C4

The SKF 6012/C4 deep groove ball bearing, with dimensions of 60x95x18 mm and increased clearance, offers reliable operation at high operating temperatures.

The 6012/C4 deep groove ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) in the SKF Explorer design. With a bore of 60 mm, an outside diameter of 95 mm and a width of 18 mm, this open bearing primarily accommodates radial and moderate axial loads. Thanks to its open design without integrated seals, the bearing is suitable for systems with an external lubrication circuit. A dimensionally stable sheet steel cage guides the rolling elements at temperatures between –20 and +150 degrees Celsius.

What is the 6012 /C4 deep groove ball bearing suitable for?

Typical applications for this open deep groove ball bearing include industrial mechanical engineering, gearboxes and electric drives. The open design is primarily used when lubricating oil or grease is supplied via the surrounding housing. Manufactured to tolerance class P6 (ABEC 3), this rolling bearing is characterised by higher concentricity compared with the standard tolerance. This makes it suitable for rotating shafts where precise guidance and low-vibration operation are required.

What are the advantages of the increased C4 bearing clearance?

The internal radial bearing clearance C4 is greater than the standard clearance and greater than the C3 grade. This design counteracts stress build-up in the bearing caused by significant temperature differences between the inner and outer rings. When heat is transferred from the shaft to the bearing during operation, the inner ring expands to a greater extent. The increased C4 bearing clearance compensates for this thermal expansion as well as tight fits, allowing the rolling elements to roll freely and reducing the risk of premature wear.
