1206J Bearing Product Overview & Core Advantages
The 1206J metric ball bearing is a double row angular contact ball bearing engineered for applications requiring high radial load capacity and compact design. Featuring an open construction, this precision bearing delivers reliable performance with its optimized internal geometry and high-grade materials. Its ability to accommodate significant combined loads makes it suitable for demanding industrial environments where space constraints and high rigidity are critical factors.
1206J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1206 | Standard metric series designation indicating bore diameter (30mm) and dimensional series |
| J | Internal design suffix indicating optimized internal geometry and radial internal clearance of CN group |
| No Seal Designation | Open construction allows for maximum limiting speed and custom lubrication options |
1206J Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides enhanced stiffness and stability, effectively resisting deflection under heavy radial dynamic load conditions. This makes the bearing particularly suitable for applications requiring precise shaft positioning.
Superior Load Capacity: Engineered with optimized raceway geometry and chrome steel components, this bearing delivers exceptional radial static load rating of 1046 lbf and dynamic capacity of 3510 lbf, ensuring reliable performance in demanding applications.
High-Speed Capability: The steel cage construction and open design enable operation at limiting speeds up to 15,000 rpm, making it ideal for high-rotation applications.
Precision Engineering: Manufactured with tight dimensional tolerances (bore: -0.01mm to 0, OD: -0.013mm to 0) and standard CN clearance, ensuring consistent performance and easy installation.
1206J Bearing Typical Application Areas
- Electric Motors and small machinery requiring compact bearing dimensions
- Industrial Gearboxes and transmission systems
- Material Handling Equipment with moderate speed requirements
- Agricultural Machinery components and implements
- General Industrial Machinery where reliable radial load support is essential
