71917 CE/HCP4ADGA Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces friction and heat generation, enabling higher limiting speeds (17,000 rpm) while maintaining dimensional stability.
Precision Phenolic Cage: The phenolic resin cage provides excellent dimensional stability and low friction operation, contributing to smooth rotation at high speeds and reduced vibration levels.
Universal Matching Capability: As a universal matchable (SU) bearing, the 71917 CE/HCP4ADGA can be paired with another identical bearing in any combination to achieve the required preload and stiffness without selective matching.
High Load Capacity: With a dynamic load rating of 10,980 lbf and static load rating of 10,238 lbf, this bearing delivers reliable performance under demanding combined loading conditions.
Precision Manufacturing: The P4A tolerance class ensures tight dimensional control with bore and outside diameter tolerances of -0.004mm to 0, guaranteeing consistent high-precision performance.
