Deep Groove Ball Bearings SKF 6201 -2Z/C3

The SKF 6201-2Z/C3 deep groove ball bearing combines dimensions of 12x32x10 mm with increased bearing clearance for rotating systems operating at temperatures up to 120 degrees Celsius.

This single-row deep groove ball bearing 6201 -2Z/C3 accommodates radial loads as well as axial forces in both directions. The design is part of the SKF Explorer range and is manufactured from standard 100Cr6 rolling bearing steel. Thanks to the sheet metal cover plates on both sides, the interior is protected from solid dirt particles. As the sealing elements are arranged in a non-contact manner, there is no additional frictional resistance, as is common with abiding sealing lips. The lubricant remains inside the bearing.

For which operating conditions is the 6201-2Z/C3 deep groove ball bearing suitable?

Design engineers use this rolling bearing when shaft bearings are operated at constant speeds and heat is generated. Typical applications include rotating machine shafts, gearbox stages and guide rollers. As the component withstands radial forces and the increased C3 bearing clearance accommodates thermal linear expansion, this design proves its worth in situations where the shaft or housing is subject to continuous heating. The cylindrical outer ring without a ring groove allows for a precise fit in smooth bores.

What are the characteristics of C3 bearing clearance and cover plates?

The internal C3 bearing clearance exceeds the standard range and prevents the rolling elements and raceways from becoming distorted due to temperature differences between the inner and outer rings. In addition, the 2Z cover plates on both sides keep solid foreign particles out without increasing friction. The integrated sheet steel cage guides the rolling elements precisely. Together with dimensional accuracy to tolerance class P6 and running accuracy P5, the bearing is designed for operation from -20 to +120 degrees Celsius.
