71922 ACE/HCP4A Bearing Product Overview & Core Advantages
The 71922 ACE/HCP4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional performance. This metric series bearing features a 25° contact angle and is manufactured to P4 (ABEC-7) tolerance class, ensuring superior running accuracy and dimensional stability. Its core advantages include the ability to accommodate combined radial and axial loads simultaneously, excellent high-speed capabilities with a limiting speed of 19,000 rpm, and optimized performance through preload availability for enhanced system rigidity.
71922 ACE/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| ACE | Angular Contact design, 25° contact angle | Optimized for combined loads and high-speed operation |
| HC | Hybrid Ceramic (Ceramic balls with steel rings) | Reduced friction, higher speed capability, and longer service life |
| P4A | P4 tolerance class with specific internal clearance | Ultra-precision performance for demanding applications |
71922 ACE/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces friction, enables higher operating speeds, and provides superior resistance to wear and electrical erosion.
Precision Phenolic Cage: The phenolic resin cage offers excellent dimensional stability at high speeds, reduced weight for lower centrifugal forces, and compatibility with various lubrication systems.
High-Precision Design: Manufactured to P4 tolerance class with tight dimensional tolerances (bore: -0.008mm to 0, OD: -0.009mm to 0) ensuring precise fitment and minimal runout in critical applications.
Optimized Load Capacity: With a radial dynamic load rating of 8,482 lbf and static load rating of 7,312 lbf, this bearing delivers reliable performance under demanding operating conditions.
