Deep Groove Ball Bearings SKF 6314 /C3

The SKF 6314/C3 single-row deep groove ball bearing, measuring 70x150x35 mm and featuring increased C3 clearance, offers reliable running characteristics under thermal loads.

This open deep-groove ball bearing 6314/C3 primarily accommodates radial forces as well as axial loads in both directions. Manufactured from standard rolling-element bearing steel 100Cr6 and fitted with a dimensionally stable sheet steel cage, the component is specified for thermal conditions ranging from –20 to +150 degrees Celsius. It is manufactured to tolerance class P0 or ABEC 1. As neither cover plates nor sealing washers are fitted, the lubricant can circulate directly around the rolling elements.

What is the 6314/C3 deep groove ball bearing suitable for in mechanical engineering?

This design is primarily used in rotating shaft bearings where higher temperatures or speeds occur during operation. Thanks to its design without integrated seals, the ball row runs with low friction in an oil bath or in grease-lubricated housings. The cylindrical outer ring, which has no groove or flange, can be fitted into standardised housing bores and facilitates direct mounting.

What distinguishes the increased C3 radial clearance in this deep-groove ball bearing?

The abbreviation C3 denotes an increased internal radial clearance compared with standard bearing clearance. This additional operating clearance counteracts stresses when the shaft or housing heats up and expands during operation. Furthermore, the clearance compensates for fit oversizes once the bearing is installed. As this is an unsealed rolling bearing, an external housing seal protects the bearing assembly against the ingress of contaminants.
