Product Description
1. Product Overview

7212B is single row angular contact ball bearing. Suffix B represents 40° contact angle. It can bear combined radial load and unidirectional axial load. Larger contact angle provides stronger axial bearing capacity compared to A and C variants. For bidirectional axial load requirements, bearings need to be installed in paired configurations. Widely applied in industrial gearboxes, air compressors, centrifugal pumps, fan assemblies and medium-heavy load rotary mechanical assemblies.

Formal quotation will be sent within 24 hours upon your inquiry.

8. FAQ
Q1: What does B stand for?
B = 40° contact angle.
Q2: Main dimensions of 7212B?
60×110×22 mm single row angular contact ball bearing.
Q3: Installation tip?
Single bearing only bears one-way axial load; adopt matched pairs for bidirectional axial force.
