1207C3 Bearing Product Overview & Core Advantages
The 1207C3 is a double row angular contact ball bearing designed for applications requiring high load capacity and operational stability. This precision bearing excels in handling significant combined loads—simultaneous radial and axial forces—making it an ideal choice for compact, high-performance assemblies. Its C3 radial internal clearance is specifically suited for applications with thermal expansion or where interference fits are used, ensuring reliable performance under varying operational conditions. The bearing comes pre-lubricated for immediate use and features a robust nylon cage for smooth, high-speed operation.
1207C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 1207 | Standard bearing series designation | Indicates the basic bearing dimensions: 35mm bore, 72mm OD, 17mm width |
| C3 | Radial internal clearance group | Provides greater than normal internal clearance for applications with thermal gradients or tight fits |
1207C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row construction provides superior stiffness and enables the bearing to support substantial radial dynamic loads (4275 lbf) and radial static loads (1350 lbf). This design is inherently more stable under combined loading conditions compared to single row bearings.
Optimized High-Speed Performance: The lightweight, nylon cage minimizes centrifugal forces and ensures stable guidance of the balls, contributing to the high limiting speed of 13,000 rpm. This makes the bearing suitable for demanding high-speed applications.
Precision Engineering & Reliability: Manufactured from chrome steel for both rings and balls, the bearing offers excellent wear resistance and durability. The open seal type allows for easy re-lubrication in service, while the pre-lubrication facilitates immediate start-up.
