3308 A-2RS1 Bearing Product Overview & Core Advantages
The 3308 A-2RS1 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and precise operation. Its design enables it to simultaneously support substantial combined loads (radial and bidirectional axial loads) efficiently. The sealed construction with pre-applied lubricant ensures long-term performance and reliability, making it an ideal choice for high-precision machinery and demanding industrial environments where space constraints and operational stability are critical.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 3308 | Standard bearing series designation, indicating a 40mm bore, 90mm OD, and 36.5mm width. |
| A | Signifies a 30° contact angle, optimized for supporting high axial loads. |
| 2RS1 | Indicates the bearing is fitted with two rubber seals (RS1 type) on both sides, providing excellent protection against contaminants and retaining lubricant. |
3308 A-2RS1 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction and 30° contact angle provide superior rigidity, enabling the bearing to handle significant combined radial and axial loads with minimal deflection.
- Precision & Durability: Manufactured to P6 (ABEC-3) tolerance class with chrome steel rings and balls and a stainless steel cage, ensuring consistent high-speed performance, dimensional accuracy, and extended service life.
- Maintenance-Free Operation: The integral 2RS1 rubber seals effectively shield the internal components from dust and moisture, while the factory-applied lubricant allows for reliable operation across a temperature range of -30°C to 110°C without requiring re-lubrication.
3308 A-2RS1 Bearing Typical Application Areas
This precision bearing is ideally suited for:
- Machine Tool Spindles and high-precision rotating units
- Gearboxes and power transmission systems
- Industrial Pumps and compressors
- Material Handling Equipment
- Other machinery requiring robust support for combined loads and reliable, sealed operation.
