R2AFF Bearing Product Overview & Core Advantages
The R2AFF single row deep groove ball bearing is a precision-engineered inch-series component designed for reliable performance in radial load applications. Featuring an open design and manufactured to ABEC 1 precision class, this bearing delivers consistent operation and long service life. Its compact dimensions (0.125" bore, 0.5" OD) make it ideal for space-constrained assemblies requiring high rotational accuracy. Constructed entirely from chrome steel for durability, it offers excellent resistance to wear and is compliant with RoHS and REACH standards for global applications.
R2AFF Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| R2AFF | Basic bearing designation for inch series single row deep groove ball bearing |
| Open | No seals or shields, allowing for maximum speed capability and easy relubrication |
| CN clearance | Normal radial internal clearance suitable for most operating conditions |
R2AFF Bearing Structural Features & Performance Benefits
This bearing's single row deep groove construction provides optimal performance for radial loads while accommodating moderate axial loads in both directions. The chrome steel cage ensures stable ball guidance and contributes to the bearing's high limiting speed of 53,000 rpm. The open design allows for versatile lubrication options and efficient heat dissipation. With ABEC 1 precision and tight dimensional tolerances, this bearing delivers smooth operation and minimal vibration, making it suitable for applications requiring consistent rotational accuracy.
