Deep Groove Ball Bearings SKF 6312 /C3

The SKF 6312/C3 deep-groove ball bearing, with a 60 mm bore and increased C3 clearance, offers reliable operation at elevated operating temperatures.

This single-row deep groove ball bearing 6312/C3 is designed as an open bearing without integrated sealing washers. It primarily accommodates radial loads as well as moderate axial forces in both directions. Manufactured from standard roller bearing steel 100Cr6, the rings and rolling elements offer high dimensional stability. The robust sheet steel cage guides the rolling elements evenly, which helps to ensure low-vibration operation. The design is suitable for a temperature range of -20 to +150 degrees.

What is the 6312 /C3 deep groove ball bearing suitable for?

Design engineers and maintenance personnel frequently use this bearing type for rotating machine components and mountings requiring precise shaft guidance. As the bearing has an open design, it is primarily suitable for oil- or grease-lubricated installations with external housing seals. This design proves its worth in applications where there is a continuous supply of lubricant and where grease or oil can circulate freely through the interior of the bearing.

What distinguishes the C3 bearing clearance from the standard version?

The C3 designation indicates a slightly increased radial bearing clearance compared to the standard clearance. This additional clearance between the balls and raceways helps to compensate for thermal expansion during operation or constrictions caused by fixed bearing seats. The component complies with tolerance class P0/PN (ABEC 1). A cylindrical outer ring without a flange or groove facilitates direct fitting into standard housings.
