1202 Bearing Product Overview & Core Advantages
The 1202 metric double row ball bearing represents a compact, high-performance solution designed for applications requiring substantial radial load capacity in a limited space. Its double row construction provides enhanced rigidity and stability compared to single row designs, making it ideal for precision machinery. Manufactured from high-grade chrome steel and featuring a lightweight nylon cage, this bearing is optimized for smooth operation and is pre-lubricated for immediate use, ensuring high reliability and long service life in demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1202 | Standard metric series designation indicating a double row, open-type ball bearing with a 15mm bore and 35mm outside diameter. |
| Open (Seal Type) | No integral seals or shields, allowing for higher speed capability and easier re-lubrication, but requiring a clean operating environment. |
| CN (Radial Clearance) | Standard radial internal clearance for normal operating conditions and fits. |
| Nylon Cage | Lightweight polymer cage contributes to lower friction, quieter operation, and is suitable for high-speed applications. |
1202 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides superior radial stiffness, enabling it to handle significant radial loads (Dynamic: 1667 lbf / Static: 396 lbf) and moderate axial loads in both directions, making it suitable for applications with combination loads.
- Optimized for High Speeds: The lightweight nylon cage minimizes centrifugal forces and friction, supporting a high limiting speed of 28,000 rpm. The open design facilitates efficient heat dissipation.
- Precision & Reliability: Manufactured with tight dimensional tolerances (Bore: -0.008mm to 0) and standard CN radial clearance, this precision bearing ensures consistent performance and accurate rotational motion.
- Ready-to-Use & Durable: Pre-lubricated and constructed from hardened chrome steel, the bearing offers excellent wear resistance and is ready for installation, reducing initial setup time.
1202 Bearing Typical Application Areas
This versatile double row ball bearing is engineered for a wide range of industrial applications where compact size, high radial load capacity, and precision are critical. Common uses include:
- Small Electric Motors and Gearboxes
- Precision Spindles and Machine Tool Accessories
- Office Automation Equipment (Printers, Scanners)
- Medical and Dental Handpieces
- Pumps, Fans, and Light-duty Conveyor Systems
