Deep Groove Ball Bearings FAG 6213 -C3

The FAG 6213-C3 deep-groove ball bearing, measuring 65 × 120 × 23 mm and featuring increased bearing clearance, offers reliable running characteristics under thermal loads.

As a single-row rolling bearing, the 6213-C3 deep groove ball bearing primarily accommodates radial forces as well as axial loads in both directions. Manufactured from standard rolling bearing steel 100Cr6, this model is characterised by dimensional stability and strength. The open design allows for targeted lubricant supply via the surrounding machine housing. With a bore of 65 mm, an outside diameter of 120 mm and a width of 23 mm, the geometry complies with common industry standards for medium-sized shafts.

What is the 6213-C3 deep groove ball bearing suitable for in industrial applications?

This open ball bearing is typically used in bearing arrangements subject to combined radial and axial loads. As it is designed without integrated sealing washers, the component is suitable for enclosed assemblies in which oil or grease lubrication is supplied externally. The built-in sheet steel cage guides the rolling elements with low friction. Design engineers select this type when dealing with compact installation spaces featuring defined shaft diameters and varying radial forces.

What does the C3 bearing clearance mean when designing the bearing arrangement?

The designation C3 indicates an increased radial bearing clearance compared with the standard version. This additional clearance between the rolling elements and raceways compensates for thermal expansion that may occur at operating temperatures between –20 and +150 degrees. Tight fits on the shaft and housing also reduce the operating clearance after assembly. With tolerance class P0, the bearing offers a defined concentricity, whilst the absence of seals keeps friction losses to a minimum.
