7013 CEGA/HCP4A Bearing Product Overview & Core Advantages
The 7013 CEGA/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. Engineered with ceramic balls and manufactured to P4A super precision tolerance, this bearing delivers superior high-speed capability and rigidity. Its 15° contact angle is optimized for handling combined loads, efficiently supporting both radial and axial forces. As part of a universally matchable set, it enables simplified installation and optimal preload configuration in high-reliability systems.
7013 CEGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CEGA | Enhanced design with phenolic cage and ceramic balls for high-speed operation |
| HC | Hybrid Ceramic construction (steel rings with ceramic balls) |
| P4A | Super precision tolerance class with enhanced running accuracy |
7013 CEGA/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces centrifugal forces, enabling higher limiting speeds (31,000 rpm) while providing electrical insulation and reduced thermal expansion.
Phenolic Cage Design: The lightweight phenolic resin cage offers excellent dimensional stability at high speeds, contributing to smooth operation and reduced vibration in precision applications.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control (bore and OD tolerance: -0.004mm to 0), ensuring consistent performance and minimal runout in critical applications.
Universal Matching Capability: Designed as part of a universally matchable set of 4 bearings, allowing for flexible mounting arrangements and simplified preload adjustment without selective assembly.
