3207 A-2RS1TN9/MT33 Bearing Product Overview & Core Advantages
The 3207 A-2RS1TN9/MT33 is a metric double row angular contact ball bearing engineered 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. Its precision P6 (ABEC-3) tolerance ensures smooth, quiet operation, while the integrated sealing and pre-lubrication deliver long-term, maintenance-free performance.
3207 A-2RS1TN9/MT33 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 3207 | Basic bearing designation; indicates a double row angular contact ball bearing with a 35mm bore. |
| A- | Contact angle of 30°, optimized for carrying significant axial loads. |
| 2RS1 | Features contact seals on both sides, providing superior protection against contaminant ingress compared to non-contact shields. |
| TN9 | Indicates a stainless steel, snap-type cage, which contributes to high-speed capability and corrosion resistance. |
| MT33 | Specifies the use of a high-performance lithium soap complex grease, suitable for a wide temperature range (-30°C to 110°C) and offering excellent longevity. |
3207 A-2RS1TN9/MT33 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides a significantly stiffer support structure than single row bearings, enabling it to handle heavy combined loads and high bidirectional axial thrust with minimal deflection.
Optimized High-Speed Performance: The lightweight TN9 stainless steel cage minimizes centrifugal forces, while the optimized MT33 lubrication reduces friction, collectively supporting the bearing's high limiting speed of 6,300 rpm.
Maintenance-Free Service Life: The combination of 2RS1 contact seals and factory-filled MT33 grease creates a sealed, lubricated-for-life system. This design prevents lubricant leakage and contaminant entry, ensuring reliable operation without the need for re-lubrication.
