1207J Bearing Product Overview & Core Advantages
The 1207J is a double row angular contact ball bearing designed for applications requiring robust support under combined loads. This metric bearing features an open design without seals, making it suitable for systems where external lubrication is provided. Its compact bearing dimensions (35mm bore, 72mm OD, 17mm width) enable space-saving installations while delivering high rigidity through its double-row ball configuration. Manufactured from chrome steel, it offers excellent durability and is pre-lubricated for immediate operation within a temperature range of -30° to 110°C.
1207J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1207 | Standard bearing designation indicating metric dimensions (35mm bore, 72mm OD) |
| J | Steel cage material designation, providing strength and durability |
| (No Seal Code) | Open construction for applications requiring external lubrication systems |
1207J Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior radial stiffness and can accommodate significant combined loads (4275 lbf dynamic, 1350 lbf static ratings). This makes it ideal for applications requiring stable rotational accuracy under varying load conditions.
Optimized Internal Geometry: With a CN radial internal clearance and precisely calculated shoulder diameters (inner: 47mm, outer: 60.9mm), the bearing ensures optimal load distribution and alignment capabilities.
High-Speed Performance: The steel cage (J designation) and optimized internal design enable reliable operation at limiting speeds up to 13,000 rpm, making it suitable for high-speed applications.
Material Excellence: Constructed from chrome steel for both rings and balls, the bearing delivers exceptional wear resistance and fatigue strength, ensuring long service life in demanding environments.
