1207JC3 Bearing Product Overview & Core Advantages
The 1207JC3 is a double row angular contact ball bearing designed for applications requiring robust support for combined loads. This metric series bearing features an open design without integral seals, optimized for high rigidity and precise operation. Its compact construction with a 35 mm bore and 17 mm width provides excellent space efficiency while delivering reliable performance in demanding industrial environments. The bearing comes pre-lubricated and features a C3 radial internal clearance, making it suitable for applications with thermal expansion considerations.
1207JC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1207 | Basic bearing designation indicating 35 mm bore diameter and standard dimensions |
| J | Steel cage construction for enhanced durability |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or interference fits |
1207JC3 Bearing Structural Features & Performance Benefits
Double Row Design: The two rows of balls provide superior rigidity and load distribution, enabling the bearing to handle significant combined radial and axial loads simultaneously. This construction makes it ideal for applications requiring stable rotational accuracy under complex loading conditions.
Optimized Material Selection: Manufactured from chrome steel for both rings and balls, the bearing delivers excellent wear resistance and fatigue life. The steel cage ensures reliable performance at the limiting speed of 13,000 rpm, maintaining ball alignment and reducing friction.
Precision Engineering: With tight dimensional tolerances on bore diameter (-0.012mm to 0) and outside diameter (-0.013mm to 0), the bearing ensures precise fitment and consistent performance. The C3 clearance provides operational flexibility for applications experiencing thermal expansion or requiring interference fits.
Temperature Compatibility: Operating temperature range of -30°C to 110°C allows for use in various environmental conditions, while the pre-lubrication ensures immediate startup and initial protection.
