Deep Groove Ball Bearings SKF 6317 /C3

The SKF 6317 /C3 deep groove ball bearing, with dimensions of 85x180x41 mm and increased C3 clearance, offers a high level of operational reliability under thermal loads.

The 6317 /C3 deep groove ball bearing is designed as a single-row radial rolling bearing for demanding industrial applications. With a bore of 85 mm, an outer diameter of 180 mm and a width of 41 mm, this design primarily accommodates radial loads and, in addition, moderate axial forces in both directions. As this is an open bearing without integrated seals, lubrication is flexibly supplied via the machine housing using grease or lubricating oil.

In which installation scenarios does the 6317/C3 deep-groove ball bearing prove its worth?

This rolling bearing is primarily used in industrial shaft mountings where significant heating occurs during operation. Manufactured to tolerance class P0/PN or ABEC 1, the component fits precisely into standardised bearing seats. The robust sheet steel cage guides the balls evenly and reliably withstands the mechanical stresses of continuous operation.

What is the function of the increased radial clearance C3?

The suffix C3 denotes an increased radial bearing clearance compared with the standard version. If the shaft and inner ring heat up more than the surrounding machine housing during operation, the additional bearing clearance compensates for this thermal expansion. This effectively helps to prevent stress and the rolling elements from becoming jammed. The temperature range specified for this component is from -20 to +150 degrees Celsius.
