71913 CD/HCP4ADGA Bearing Product Overview & Core Advantages
The 71913 CD/HCP4ADGA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This universal matchable (SU) bearing features a 15° contact angle and extra light preload (Class A), making it ideal for applications requiring minimal deflection under combined loads. Its ceramic ball construction and P4A tolerance class ensure superior high-speed capability and rotational accuracy, while the phenolic cage contributes to reduced friction and weight.

71913 CD/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 (31,000 rpm) while providing excellent electrical insulation properties and extended service life.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control (bore/OD tolerance: -0.004mm to 0), ensuring consistent performance in high-precision applications.
Optimized Cage Design: The phenolic cage offers excellent strength-to-weight ratio, reduced friction, and compatibility with various lubrication types, contributing to the bearing's high-speed capability.
Universal Matching Capability: As an SU-type bearing, it can be mounted in any combination (back-to-back, face-to-face, or tandem) without pre-load adjustment, providing design flexibility for complex bearing arrangements.
