7005 ACDGA/HCP4A Bearing Structural Features & Performance Benefits
Ceramic Ball Technology: Silicon nitride (ceramic balls) significantly reduce centrifugal forces, enabling higher limiting speeds (85,000 rpm) while providing excellent electrical insulation and corrosion resistance.
Phenolic Resin Cage: The phenolic cage offers superior strength-to-weight ratio, reduced friction, and excellent dimensional stability at high speeds, contributing to smooth operation and extended bearing life.
Precision Ground Components: Manufactured to P4A tolerance class with tight dimensional controls (bore and OD tolerance: -0.004mm to 0), ensuring precise fitment and optimal performance in precision machinery.
Universal Matching Capability: Designed as Universal Matchable (SU) bearings, they can be supplied in matched sets of 3 for optimized preload configurations in spindle applications.
