Deep Groove Ball Bearings FAG 6306 -2Z-C3

The FAG 6306 -2Z-C3 deep-groove ball bearing, with dimensions of 30x72x19 mm, cover plates on both sides and a C3 clearance, offers reliable operation at higher speeds.

The FAG 6306 -2Z-C3 deep groove ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6). It absorbs radial forces and provides axial support for shafts in both directions. The sheet metal covers on both sides shield the interior from coarse dirt particles, whilst the sheet steel cage guides the rolling elements. With tolerance class P0 (ABEC 1), this bearing meets standard industrial requirements.

What is the 6306 -2Z-C3 deep groove ball bearing suitable for in operation?

This radial ball bearing is primarily used in applications where there is moderate contamination and low friction losses are required. The non-contacting cover plates do not generate any additional frictional torque, meaning the bearing remains suitable for higher speeds. With a temperature range of -30 to +120 degrees, the component operates reliably even when ambient temperatures fluctuate.

What does the C3 bearing clearance mean when selecting a bearing?

The designation C3 indicates an increased radial bearing clearance compared with the standard version. This additional clearance between the balls and raceways is relevant when tight fits on the shaft or housing cause the inner ring to expand or the outer ring to contract. Similarly, the C3 clearance compensates for thermal expansion when temperature differences arise between the inner and outer rings during operation. This reduces the risk of seizing and promotes smooth running.
