3206 A-2RS1TN9/MT33 Bearing Product Overview & Core Advantages
The 3206 A-2RS1TN9/MT33 is a double row angular contact ball bearing engineered for applications requiring high precision and reliability. This sealed bearing is designed to accommodate combined loads—simultaneously handling significant radial loads and bidirectional axial loads. Its compact design and high rigidity make it an ideal solution for space-constrained, high-performance machinery. Pre-lubricated with high-performance grease and featuring effective sealing, it delivers long-lasting, maintenance-free operation in demanding environments.
3206 A-2RS1TN9/MT33 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 3206 | Basic designation indicating bore diameter (30mm), outside diameter (62mm), and width (23.8mm) | Standardized bearing dimensions for easy integration |
| A | Contact angle of 30° | Optimized for handling axial loads |
| 2RS1 | Double-sided contact seals | Superior protection against contaminants, enhanced sealing performance |
| TN9 | Stainless steel cage, polymer reinforced | Excellent for high-speed applications, reduced friction |
| MT33 | High-temperature, high-speed grease | Extended lubrication life, stable performance across temperature range (-30° to 110°C) |
3206 A-2RS1TN9/MT33 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to handle substantial combined loads (radial dynamic load rating: 6862 lbf, static: 4950 lbf). The optimized contact angle ensures efficient management of bidirectional axial forces.
High-Speed Performance: The TN9 stainless steel cage minimizes centrifugal forces and friction, contributing to a high limiting speed of 7,500 rpm. Combined with MT33 grease, it ensures stable operation at elevated rotational speeds.
Maintenance-Free & Long Service Life: The integrated 2RS1 contact seals effectively retain lubrication and exclude contaminants. Pre-lubrication with MT33 grease eliminates the need for re-lubrication, ensuring reliable, long-term performance.
Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class, this bearing guarantees running accuracy, low vibration, and consistent performance in precision applications.
