7016 CD/HCP4ATBTC Bearing Product Overview & Core Advantages
The 7016 CD/HCP4ATBTC is a high-precision angular contact bearing designed for demanding applications requiring exceptional rigidity and speed performance. This matched triplex set features three bearings arranged in a back-to-back configuration (TBT), delivering superior stiffness and moment load capacity. Manufactured to P4A tolerance class with ceramic balls and a phenolic cage, it offers outstanding dimensional stability, reduced friction, and extended service life in high-speed rotational systems.
7016 CD/HCP4ATBTC Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 7016 | Standard bore diameter (80 mm) and series designation | Standardized bearing dimensions for interchangeability |
| CD | Moderate preload (Class C) | Optimized rigidity and running accuracy |
| HCP4A | P4A tolerance class with enhanced running accuracy | Superior precision bearing performance |
| TBT | Triplex Back-to-Back arrangement | Maximum moment stiffness and load distribution |
7016 CD/HCP4ATBTC Bearing Structural Features & Performance Benefits
- Triplex Back-to-Back Design: Three bearings in TBT arrangement provide exceptional system rigidity and resistance to moment loads, making them ideal for applications requiring high positional accuracy.
- Ceramic Ball Technology: Silicon nitride balls reduce centrifugal forces, lower operating temperatures, and enable higher limiting speeds (28,000 rpm) while providing electrical insulation properties.
- Phenolic Cage Construction: Lightweight composite cage offers excellent strength-to-weight ratio, reduced inertia, and superior performance at high rotational speeds.
- P4A Precision Tolerance: Tight dimensional tolerances (bore: -0.004mm to 0, OD: -0.004mm to 0) ensure consistent performance and minimal runout in precision applications.
- 15° Contact Angle: Optimized for combined radial and axial load capacity while maintaining high-speed capability.
7016 CD/HCP4ATBTC Bearing Typical Application Areas
- Machine Tool Spindles: High-speed machining centers and grinding spindles requiring precision and thermal stability
- Precision Robotics: Articulated arms and positioning systems demanding high rigidity and accuracy
- Aerospace Systems: Flight control mechanisms and auxiliary power units
- Medical Equipment: High-speed dental handpieces and surgical drill systems
