3305 A-2RS1 Bearing Product Overview & Core Advantages
The 3305 A-2RS1 is a double row angular contact ball bearing designed for applications requiring high rigidity and the ability to handle combined loads. This sealed precision bearing simultaneously supports substantial radial loads and bidirectional axial loads, making it ideal for compact arrangements where space is limited. Manufactured to P6 (ABEC-3) tolerance class, it ensures high running accuracy and operational reliability. The integrated seals and pre-lubrication contribute to its long service life with minimal maintenance, establishing it as a robust solution for demanding industrial environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 3305 | Basic bearing series designation, indicating a 25 mm bore, 62 mm OD, and 25.4 mm width. |
| A | Denotes a 30° contact angle, optimized for carrying high axial loads. |
| 2RS1 | Signifies contact seals on both sides (RS1 type), providing excellent protection against contaminant ingress and retaining lubricant. |
3305 A-2RS1 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design and 30° contact angle provide superior rigidity, enabling the bearing to effectively support combined radial and axial loads from both directions. With a dynamic load rating of 7312 lbf and a static load rating of 4950 lbf, it is built for high-stress applications.
Optimized for Performance: The stainless steel cage ensures stability and contributes to smooth operation at the specified limiting speed of 7,500 rpm. The combination of chrome steel rings and balls provides excellent wear resistance and durability.
Maintenance-Free Operation: The integral 2RS1 contact seals effectively shield the bearing interior from contaminants while retaining the factory-applied lubricant. This sealed and pre-lubricated construction ensures long-term, maintenance-free operation within a wide temperature range of -30°C to 110°C.
3305 A-2RS1 Bearing Typical Application Areas
The 3305 A-2RS1 is ideally suited for a variety of industrial machinery and precision equipment, including:
- Industrial Gearboxes and Power Transmission Systems
- Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Electric Motors and Medium-Duty Machine Tool Spindles
