Deep Groove Ball Bearings SKF 6207 -Z/C3

The SKF 6207 -Z/C3 deep groove ball bearing, with dimensions of 35x72x17 mm and a C3 clearance, offers reliable running characteristics under thermal loads.

The SKF 6207 -Z/C3 deep groove ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) for rotating shafts with a diameter of 35 mm. As a versatile component, this design primarily accommodates radial forces as well as moderate axial loads in both directions. The design combines a sturdy sheet steel cage with a single-sided sheet metal cover. This leaves one side of the bearing accessible for lubricant entry, whilst the protected side prevents the ingress of coarse dirt particles.

What is the 6207 -Z/C3 deep groove ball bearing suitable for in industrial applications?

In industrial applications, the 6207 -Z/C3 deep groove ball bearing is particularly suitable for rotating assemblies in which shafts generate heat during operation. Thanks to its P0/PN (ABEC 1) tolerance class, the component fits precisely into standardised bearing seats. The single-sided Z-cover proves useful in sealed housings where lubricating oil circulates, but where the opposite side needs to be shielded from dirt particles. The permissible temperature range is from -20 to +150 degrees Celsius.

What advantages do the C3 bearing clearance and the Z-cover offer when selecting bearings?

The increased C3 radial clearance compensates for dimensional changes when the shaft and inner ring heat up during operation. This prevents the rolling elements from becoming stressed due to thermal expansion. In addition, the non-contact Z-cover generates no additional frictional heat, as there is no sliding sealing contact. In terms of design, the open side faces the lubricant side, tailored to the main dimensions of a 35 mm bore, 72 mm outer diameter and 17 mm width.
