S7014 ACDGA/HCP4A Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The use of ceramic balls with a steel ring significantly reduces centrifugal forces, lowers operating temperature, and enables a limiting speed of 22,000 rpm. This makes it a superior high-speed bearing.
High Rigidity & Load Capacity: The 25° contact angle and precision grinding provide high resistance to deflection under combined loads, offering a dynamic load rating of 10,980 lbf and static load rating of 9,900 lbf for reliable performance.
Precision & Stability: Manufactured to P4A tolerance class with an extra light preload, this bearing ensures minimal runout and exceptional rotational accuracy, which is critical for precision machining.
Sealed & Lubricated for Life: The integral seals retain the factory-applied grease lubrication, protecting against contamination and providing maintenance-free operation within the specified temperature range of -30°C to 110°C.
Phenolic Cage: The phenolic resin cage offers high strength, low weight, and excellent performance at high speeds, contributing to the bearing's overall high-speed capability.
