| Suffix Code | Technical Meaning |
|---|---|
| C | 15° Contact Angle |
| E | Optimized internal design |
| HC | Hybrid Ceramic balls (Silicon Nitride) |
| P4A | High precision tolerance class (superior to ABEC 7) |
| DT | Duplex Tandem arrangement (2 bearings matched for increased axial load capacity in one direction) |
7007 CE/HCP4ADT Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The duplex tandem arrangement and P4A tolerance class provide exceptional system stiffness and running accuracy, minimizing deflection under load.
- Enhanced Speed & Performance: The combination of a lightweight phenolic resin cage and low-friction ceramic balls significantly reduces centrifugal forces and operating temperature, enabling the high limiting speed of 56,000 rpm.
- Superior Load Capacity: The 15° contact angle and tandem configuration are optimized to handle significant axial loads in one direction, in addition to radial loads.
- Pre-Lubricated & Ready-to-Install: The bearing is factory lubricated, ensuring immediate operational readiness and consistent performance within its specified temperature range of -30°C to 110°C.
7007 CE/HCP4ADT Bearing Typical Application Areas
This high-precision, high-speed bearing is ideally suited for:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Robotics (High-accuracy robot arm joints)
- High-Frequency Motors and Spindle Drives
- Medical Equipment (Dental handpieces, laboratory centrifuges)
- Aerospace Instrumentation and Optical Positioning Systems
