Deep Groove Ball Bearings SKF 6210 /C3

The SKF 6210/C3 deep groove ball bearing, with dimensions of 50x90x20 mm and an increased C3 clearance, offers stable operation under thermal loads.

The SKF 6210/C3 single-row deep groove ball bearing is a radial rolling bearing for industrial applications. Manufactured from standard rolling bearing steel (100Cr6), the design primarily accommodates radial forces as well as moderate axial forces in both directions. The open design without seal washers allows for direct lubricant supply via an external lubrication system. The integrated sheet steel cage guides the rolling elements evenly during operation.

What operating conditions does the 6210 /C3 deep groove ball bearing require?

This design is suitable for installation locations where operational heat is generated and external seals are already in place. The outer ring without a flange allows the component to be mounted directly into housing bores. The permissible temperature range is between -20 and +150 degrees Celsius. The open design requires a clean installation environment to prevent the ingress of dirt particles.

What is the function of the C3 radial clearance when fitting this rolling bearing?

The C3 rating indicates a slightly increased radial clearance compared with the standard version. This increased radial clearance serves to compensate for temperature-induced expansion of the shaft and inner ring during operation. Tight fits also reduce the bearing clearance during press-fitting. With tolerance class P0/PN (corresponding to ABEC 1), the bearing meets standard requirements for general mechanical engineering.
