3310 A-2RS1 Bearing Product Overview & Core Advantages
The 3310 A-2RS1 is a double row angular contact ball bearing engineered for applications requiring high rigidity and precision. This sealed bearing is designed to accommodate combined loads—simultaneously handling significant radial loads and bidirectional axial loads. Its compact design integrates two rows of balls with a steep contact angle, making it ideal for high-reliability machinery where space is constrained and operational stability is critical. The pre-lubrication and integral seals ensure long-term performance with minimal maintenance.
3310 A-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 3310 | Basic bearing designation, indicating the bearing dimensions (50mm bore, 110mm OD, 44.4mm width). |
| A | Denotes a 30° contact angle, optimized for supporting high axial loads. |
| 2RS1 | Signifies the bearing is fitted with two rubber seals (RS1 type) on both sides, providing effective protection against contaminants and retaining lubricant. |
3310 A-2RS1 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to handle heavy combined loads with minimal deflection. The optimized contact angle ensures efficient distribution of bidirectional axial forces.
- Precision & Speed: Manufactured to P6 (ABEC-3) tolerance class, this precision bearing ensures smooth operation and accurate rotational performance. The stainless steel cage contributes to stable operation at the specified limiting speed of 4,300 rpm.
- Durability & Maintenance-Free Operation: The chrome steel rings and balls offer excellent wear resistance and fatigue life. The integral 2RS1 rubber seals and factory-applied lubricant create a sealed, maintenance-free system, protecting against contamination and ensuring consistent performance across its operating temperature range (-30°C to 110°C).
3310 A-2RS1 Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for demanding applications in:
- Machine Tool Spindles
- Industrial Gearboxes
- Pumps and Compressors
- Precision Agricultural Machinery
- Material Handling Equipment
