1307C3 Bearing Product Overview & Core Advantages
The 1307C3 is a double row angular contact ball bearing designed for applications requiring high radial load capacity and operational stability. Featuring an open design with C3 radial internal clearance, this precision bearing delivers reliable performance in demanding environments. Its double row construction provides high rigidity and excellent resistance to combined loads, making it suitable for applications where shaft deflection must be minimized. The bearing comes pre-lubricated for immediate installation and optimal performance.
1307C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1307 | Standard bearing designation indicating 35mm bore diameter, 80mm OD, 21mm width |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or where interference fits are used |
1307C3 Bearing Structural Features & Performance Benefits
Double Row Design: Provides enhanced radial load capacity and high rigidity compared to single row bearings, effectively resisting moment loads and shaft deflection.
Nylon Cage: The glass fiber reinforced nylon cage offers excellent performance at high speeds, contributing to reduced friction and lower operating temperatures.
C3 Clearance: The increased internal clearance accommodates thermal expansion in applications with elevated operating temperatures or interference fits, preventing premature failure.
Chrome Steel Construction: Both rings and balls are manufactured from high-quality chrome steel, ensuring long service life and reliable performance under demanding conditions.
Pre-lubricated: Factory-applied lubrication ensures immediate operation and optimal performance from initial startup.
