FAQ

What does the ‘B-2RSRTNG’ suffix mean for this NSK 3210 bearing?

The ‘B’ indicates this is a second generation design for double row angular contact ball bearings, often with a 30-degree contact angle. ‘2RS’ means it has contact-type rubber seals on both sides to protect against dust and moisture. ‘TNG’ refers to the cage material, which is a snap-type, glass-fibre reinforced polyamide 6.6 cage.

Can this bearing accommodate misalignment?

No, double row angular contact ball bearings like the 3210B are rigid and cannot accommodate any angular misalignment between the shaft and housing. Proper alignment during installation is critical for ensuring optimal performance and service life.

What kind of loads is the 3210B-2RSRTNG designed to handle?

This bearing is designed to handle combined loads, meaning it can support both radial and axial loads in both directions. It is particularly suitable for applications where rigid axial guidance is required.
