1201J Bearing Product Overview & Core Advantages
The 1201J metric ball bearing is a double row angular contact ball bearing engineered for applications requiring high load capacity and rigidity. This precision bearing is designed to accommodate significant combined loads, including radial and bidirectional axial loads, within a compact bearing size (12mm bore, 32mm OD, 10mm width). Manufactured from chrome steel with a steel cage, it offers reliable performance and is pre-lubricated for immediate use, making it ideal for high-reliability industrial applications.
1201J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1201 | Standard bearing designation indicating a metric double row angular contact ball bearing with a 12mm bore diameter. |
| J | Suffix denoting a specific internal design and radial internal clearance of CN (Normal Group). |
1201J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized raceway geometry provide superior stiffness and enable the bearing to support substantial combined radial and axial loads.
- Optimized Internal Clearance: The standard CN radial internal clearance ensures stable operation and minimal vibration under typical operating conditions and fits.
- Robust Construction: Components made from chrome steel offer high load ratings (Dynamic: 1404 lbf, Static: 322 lbf) and excellent durability.
- Ready-to-Install: The bearing comes pre-lubricated, facilitating quick installation and immediate operation upon delivery.
1201J Bearing Typical Application Areas
This bearing is suited for a wide range of industrial machinery and precision equipment, including:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Precision Spindles and Machine Tool Accessories
- Pumps and Compressors
- Material Handling Equipment
