3208 A-2RS1TN9/MT33 Bearing Product Overview & Core Advantages
The 3208 A-2RS1TN9/MT33 is a double row angular contact ball bearing engineered for applications demanding high precision and reliability. This sealed bearing excels at simultaneously supporting significant combined loads—both radial and bidirectional axial loads—within a compact design envelope. Manufactured to a P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy, making it an ideal choice for high-performance machinery where high rigidity and operational stability are paramount.
3208 A-2RS1TN9/MT33 Bearing Model Code Explained, Specifications & Naming Convention
The model number 3208 A-2RS1TN9/MT33 provides a detailed technical specification:
- 3208: Basic designation denoting a metric double row angular contact ball bearing with a 40 mm bore and 80 mm outside diameter.
- A: Signifies a specific contact angle of 30°, optimized for carrying substantial axial loads.
- 2RS1: Indicates the bearing is fitted with two rubber contact seals (RS1) on both sides, providing superior protection against contaminant ingress and lubricant leakage.
- TN9: Designates the cage material as glass fiber reinforced polyamide 66 (PA66), which is lightweight and facilitates smooth operation at high speeds.
- MT33: Specifies the bearing is pre-lubricated with a high-performance lithium soap complex grease, suitable for the specified temperature range and offering long-term, maintenance-free operation.
3208 A-2RS1TN9/MT33 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The double row design and 30° contact angle create a rigid support system capable of handling heavy combined loads from multiple directions, significantly enhancing machine stability.
- Optimized High-Speed Performance: The combination of the lightweight TN9 polymer cage and optimized internal geometry allows for a high limiting speed of 5,600 rpm, making it suitable for demanding rotational applications.
- Long-Term, Maintenance-Free Operation: The integral 2RS1 rubber contact seals effectively shield the bearing internals from contaminants. Coupled with the pre-filled MT33 grease, this ensures reliable performance over extended periods without requiring re-lubrication.
- Precision Engineering: Manufactured to P6 tolerance with tight dimensional control on the bore diameter, outside diameter, and width, this bearing guarantees consistent and precise performance in critical applications.
3208 A-2RS1TN9/MT33 Bearing Typical Application Areas
This precision bearing is ideally suited for a wide range of industrial equipment, including:
- Machine Tool Spindles
- Industrial Pumps and Compressors
- Gearboxes and Transmission Systems
- Precision Agricultural Machinery
- Material Handling Equipment
