3210 A-2RS1TN9/MT33 Bearing Product Overview & Core Advantages
The 3210 A-2RS1TN9/MT33 is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing excels at simultaneously handling combined radial and bidirectional axial loads, making it an ideal choice where high rigidity and operational reliability are paramount. Its compact design, sealed construction, and pre-lubrication ensure long service life with minimal maintenance, positioning it as a superior solution for high-speed and high-precision machinery.
3210 A-2RS1TN9/MT33 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 3210 | Basic bearing designation indicating the bearing size (50mm bore, 90mm OD). |
| A | Contact angle of 30°, optimized for carrying significant axial loads. |
| 2RS1 | Features two contact seals (RS1 type) on both sides for superior protection against contaminants and grease leakage. |
| TN9 | Indicates a stainless steel cage, polymer reinforced, enabling high-speed capability and excellent guidance. |
| MT33 | Specifies the use of a high-performance polyurea grease, suitable for a wide temperature range (-30°C to +110°C) and offering long-term lubrication. |
3210 A-2RS1TN9/MT33 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides a rigid support system, significantly increasing the bearing's ability to withstand combined loads (radial and axial acting simultaneously) and moment loads. This results in enhanced stability and precision in machine operation.
- Superior Sealing & Longevity: The two contact seals (2RS1) effectively shield the internal components from dust, moisture, and other contaminants while retaining the lubricant. This creates a maintenance-free solution for the entire grease service life, reducing downtime and total cost of ownership.
- Optimized High-Speed Performance: The combination of the lightweight, robust TN9 polymer cage and the advanced MT33 grease minimizes friction and heat generation, allowing the bearing to achieve its high limiting speed of 4,800 rpm reliably.
- Precision Engineering: Manufactured to a P6 (ABEC-3) tolerance class, this bearing ensures running accuracy, low noise, and low vibration levels, which are critical for high-precision applications.
