| G | Cage material designation (Nylon/Glass fiber reinforced) |
| 15 | Contact angle specification for optimal load distribution |
1305G15 Bearing Structural Features & Performance Benefits
Double Row Design: The double row ball bearing configuration provides enhanced rigidity and moment load capacity compared to single row designs, making it suitable for applications with significant radial and axial load combinations.
Precision Engineering: Manufactured with chrome steel rings and balls, the bearing ensures consistent performance and long service life. The nylon cage contributes to reduced friction and quieter operation at high speeds up to 15,000 rpm.
Optimized Internal Clearance: Standard CN radial clearance provides optimal performance balance for most industrial applications, accommodating thermal expansion while maintaining precision.
Load Capacity: With a dynamic load rating of 4275 lbf and static load rating of 1215 lbf, this bearing handles substantial combined loads while maintaining dimensional stability.
