Deep Groove Ball Bearings SKF 6207 -2Z/C3

The SKF deep groove ball bearing 6207 -2Z/C3, with a 35 mm bore, sheet metal shields on both sides and a C3 clearance, offers reliable protection against contamination at elevated operating temperatures.

The SKF 6207 -2Z/C3 deep groove ball bearing is a versatile radial rolling bearing made from standard bearing steel (100Cr6). As a single-row bearing, it accommodates radial loads as well as axial forces acting in both directions. With main dimensions of 35 mm inner diameter and 72 mm outer diameter, and a width of 17 mm, this component fits into numerous standardised housings. A robust sheet steel cage guides the rolling elements evenly along the raceway and maintains the bearing’s dimensional stability even under dynamic loads.

What is the 6207-2Z/C3 deep groove ball bearing suitable for?

This rolling bearing is primarily used in rotating systems that require a non-contact seal against coarse particles. These include rotating shafts in industrial drives where low friction and protection against coarse contaminants are required. The sheet metal cover plates on both sides keep out dirt particles and reduce lubricant leakage without causing friction losses due to sliding contact. This makes the design particularly well-suited to medium to high speeds under constant or varying loads.

What are the advantages of the increased C3 radial clearance?

The designation C3 indicates an increased bearing clearance compared to the standard when the bearing is unmounted. This clearance reserve compensates for heat-induced expansion of the shaft and inner ring during operation. Furthermore, the increased bearing clearance helps to prevent the rolling elements from becoming stressed when tight fits in the bearing seat cause the inner ring to expand. With the standard tolerance P0 or ABEC 1 and a permissible temperature range of -20 to +120 degrees, this variant offers a high level of operational reliability in demanding industrial environments.
