3306 A-2Z Bearing Product Overview & Core Advantages
The 3306 A-2Z is a double row angular contact ball bearing engineered for applications requiring high rigidity and precision performance. This metric bearing features a shielded design that provides effective protection against contamination while maintaining excellent operational characteristics. Its double row construction enables it to accommodate combined loads - both radial and bidirectional axial loads simultaneously - making it ideal for applications where space constraints and high reliability are critical factors. With its P6 tolerance class (equivalent to ABEC-3), this bearing delivers consistent precision performance in demanding industrial environments.
