S7012 ACD/HCP4ADGA 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 (32,500 rpm) while maintaining dimensional stability across the operating temperature range (-30°C to 110°C).
Precision Engineering: Manufactured to P4A tolerance class with extra light preload (Class A), this bearing delivers exceptional running accuracy and minimal vibration for sensitive applications.
Optimized Load Capacity: The 25° contact angle and universal matchable design provide excellent performance under combined radial and axial loads, with dynamic load rating of 14,040 lbf and static load rating of 15,075 lbf.
Advanced Cage Design: The phenolic cage offers excellent strength-to-weight ratio and smooth operation at high speeds, contributing to the bearing's overall high-speed capability.
Sealed & Lubricated: Factory-sealed and pre-lubricated with grease, ensuring maintenance-free operation and protection against contamination throughout the bearing's service life.
