| DGA | Universal Matchable (SU) bearing, designed to be paired in a set |
7007 CE/P4ADGA Bearing Structural Features & Performance Benefits
High Precision & Rigidity: Manufactured to P4A tolerance standards with extremely tight dimensional tolerances on all bearing components, ensuring minimal runout and vibration for superior positioning accuracy. The phenolic cage provides excellent dimensional stability and reduced friction at high speeds.
Optimized Load Capacity: The 15° contact angle is engineered to support significant combined radial and axial loads simultaneously. The universal matchable design allows two bearings to be paired in a back-to-back or face-to-face arrangement to handle complex load conditions and moments.
Superior High-Speed Performance: The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 56,000 rpm, making it suitable for demanding high-speed spindle applications.
Pre-Lubricated & Ready for Use: The bearing is factory-lubricated, ensuring immediate operational readiness and consistent performance across its specified temperature range of -30°C to 110°C.
7007 CE/P4ADGA Bearing Typical Application Areas
- Machine Tool Spindles: High-precision machining centers, grinding spindles, and CNC lathes.
- High-Speed Motors: Spindles for electric motors and generators requiring minimal vibration.
- Precision Instrumentation: Medical equipment, optical scanners, and measuring devices.
- Aerospace Components: Gyroscopes, navigation systems, and auxiliary power units.
