1207 EM Bearing Product Overview & Core Advantages
The 1207 EM is a double row deep groove ball bearing designed for applications demanding high radial load capacity and robust performance. Its compact bearing dimensions (35mm bore, 72mm OD, 17mm width) make it ideal for space-constrained installations. Manufactured from high-grade chrome steel with a brass cage, this precision bearing offers reliable operation and long service life. The open seal type allows for versatile lubrication options, catering to specific application needs.
1207 EM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1207 | Standard bearing series designation, indicating the metric size (35mm bore). |
| EM | Denotes an optimized internal design and the use of a brass cage (machined window type), which provides superior strength and stability for high-speed applications. |
1207 EM Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The double row construction significantly increases the radial dynamic load rating (4275 lbf) and provides greater rigidity compared to single row bearings, making it suitable for applications with heavy loads and minimal deflection requirements.
- High-Speed Performance: The robust brass cage (EM designation) ensures stable operation and guides the balls effectively, contributing to a high limiting speed of 13,000 rpm.
- Precision & Durability: Manufactured from chrome steel for both rings and balls, the bearing offers high hardness and wear resistance. The tight dimensional tolerances ensure precise running accuracy.
- Versatile Lubrication: The open design allows for the application of various greases or oils, enabling customization for specific temperature ranges (from -30°C to 110°C) and operational conditions.
1207 EM Bearing Typical Application Areas
This bearing is engineered for use in a wide range of industrial machinery, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
