FAQ

What does the open design (no suffix) of the FAG 6311 bearing mean for its application?

The open design means this bearing has no seals or shields. It is intended for applications where it will be lubricated with oil or grease within a sealed housing, protecting it from contaminants. This design allows for higher running speeds compared to sealed or shielded versions.

Is this bearing suitable for high-temperature applications?

Standard FAG 6311 bearings are typically stabilized for operating temperatures up to 120 deg C. For higher temperatures, special variants with specific heat treatments and radial internal clearance (e.g., C3 or C4 suffix) would be required. This is a standard clearance bearing.

How can I verify the authenticity of this FAG bearing?

Authentic FAG bearings have high-quality laser markings on the races, which are clear and precise. The packaging, including the box quality and label details, should be checked against official FAG standards. Schaeffler also offers authenticity check apps that can scan the data matrix code on newer boxes.
