3209 A-2RS1 Bearing Product Overview & Core Advantages
The 3209 A-2RS1 is a double row angular contact ball bearing designed for applications requiring high rigidity and precision performance. This sealed bearing excels at simultaneously handling combined radial and bidirectional axial loads, making it ideal for compact arrangements where space optimization is critical. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and reliability in demanding industrial environments.
3209 A-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 3209 | Basic bearing designation: Double row angular contact ball bearing with 45mm bore diameter |
| A | 30° contact angle for optimal axial load capacity |
| 2RS1 | Double-sided NBR contact seals providing superior protection against contamination |
3209 A-2RS1 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, enabling precise shaft positioning and reduced deflection under heavy combined loads.
Enhanced Load Capacity: With a radial dynamic load rating of 11,700 lbf and radial static load rating of 9,338 lbf, this bearing effectively manages both radial forces and substantial bidirectional axial loads.
Optimized Performance: The stainless steel cage ensures reliable operation at the limiting speed of 5,300 rpm, while the pre-lubricated design with contact seals maintains consistent performance throughout the bearing's service life.
Maintenance-Free Operation: The integrated 2RS1 seals and factory-applied lubricant create a protected environment that eliminates the need for re-lubrication, reducing maintenance requirements and downtime.
