3306 A-2RS1 Bearing Product Overview & Core Advantages
The 3306 A-2RS1 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. This sealed bearing excels at simultaneously handling combined radial and bidirectional axial loads, making it ideal for compact arrangements where space is limited. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and dimensional stability. The combination of high rigidity from its double row design and effective sealing ensures consistent performance in demanding industrial environments.

3306 A-2RS1 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact construction provides superior stiffness and enables the bearing to handle substantial combined loads (radial and axial loads acting simultaneously). The optimized contact angle ensures efficient bidirectional axial load support.
Enhanced Sealing & Lubrication: The 2RS1 rubber seals effectively shield the internal components from dust, moisture, and other contaminants while retaining the factory-applied high-quality grease. This configuration supports a temperature range of -30°C to 110°C and contributes to extended service life with minimal maintenance.
Precision Engineering: Manufactured from chrome steel rings and balls with a stainless steel cage, the bearing maintains dimensional stability under load. The P6 tolerance class ensures precise running characteristics suitable for high-speed applications up to 6,300 rpm.
