3304 A-2RS1 Bearing Product Overview & Core Advantages
The 3304 A-2RS1 is a double row angular contact ball bearing designed for applications requiring high precision and reliable performance. This sealed bearing excels at simultaneously handling combined loads, including significant radial loads and bidirectional axial loads. Its compact design offers a high load capacity within a minimal cross-section, making it ideal for space-constrained, high-rigidity applications. Manufactured to P6 (ABEC-3) tolerance class, it ensures smooth operation and precise rotational accuracy.
3304 A-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 3304 | Standard bearing series designation, indicating the bearing dimensions (20mm bore, 52mm OD, 22.2mm width). |
| A | Contact angle of 30°, optimized for carrying substantial axial loads. |
| 2RS1 | Features two-sided contact seals made from Nitrile Rubber (NBR). This provides excellent protection against contaminants and retains lubricant, ensuring long service life and maintenance-free operation. |
3304 A-2RS1 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide superior high rigidity, enabling stable support for shafts under heavy combined loads.
Sealed & Lubricated for Life: The integral 2RS1 seals effectively shield the bearing internals from dust, moisture, and other pollutants. The bearing is pre-lubricated with high-quality grease, making it ready for installation and suitable for applications where re-lubrication is difficult.
Precision Performance: Built to a P6 tolerance class with a stainless steel cage, this precision bearing ensures low noise, low vibration, and smooth running up to its limiting speed of 9,000 rpm.
Durable Construction: Components made from chrome steel offer high wear resistance and durability, supporting a wide temperature range from -30°C to 110°C.
3304 A-2RS1 Bearing Typical Application Areas
