3303 A-2RS1 Bearing Product Overview & Core Advantages
The 3303 A-2RS1 is a double row angular contact ball bearing engineered for applications requiring high precision and reliability. This sealed bearing is designed to accommodate combined loads, simultaneously handling significant radial loads and bidirectional axial loads. Its compact design and high rigidity make it an ideal solution for space-constrained, high-performance machinery. Manufactured to a P6 (ABEC-3) tolerance class, it ensures consistent, precise operation, while its integrated seals and pre-lubrication offer long-term, maintenance-free performance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 3303 | Basic bearing series, indicating the bearing dimensions (17 mm bore, 47 mm OD). |
| A | Contact angle of 30°, optimized for carrying high axial loads. |
| 2RS1 | The bearing features two contact seals (RS1 type) on both sides, providing excellent protection against contaminants and retaining lubricant. |
3303 A-2RS1 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and 30° contact angle create a robust structure capable of supporting high radial dynamic load ratings (4860 lbf) and static load ratings (2858 lbf), making it suitable for applications with significant combined loads.
- Sealed & Lubricated for Long Life: The integral 2RS1 seals effectively shield the internal components from dust, moisture, and other contaminants. The bearing is pre-lubricated, ensuring immediate operation and long-term, maintenance-free service within a wide temperature range of -30°C to 110°C.
- Precision Engineering: Manufactured from chrome steel rings and balls with a stainless steel cage, the bearing guarantees high durability and corrosion resistance. The P6 tolerance class ensures precise running accuracy for smooth and quiet operation.
- Optimized Geometry: The design includes a defined load point (28 mm from the side face), which is critical for accurate mounting and optimal load distribution in the application.
3303 A-2RS1 Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for a wide range of demanding industrial applications, including:
- Electric Motors and Gearboxes
