71914 CE/HCP4ADGA Bearing Product Overview & Core Advantages
The 71914 CE/HCP4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and high-speed performance. Engineered to a P4A tolerance class, this bearing is capable of simultaneously supporting combined loads (radial and axial) in a compact, 32 mm width design. Its ceramic ball construction and universal matchable (SU) designation enable superior operational characteristics, making it ideal for high-reliability, high-rigidity applications.
71914 CE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
- 71914: Basic bearing series and size designation (70 mm bore, 100 mm OD).
- CE: Indicates a 15° contact angle and specific internal design optimized for high-speed operation.
- HC: Signifies the use of Hybrid Ceramic balls, offering reduced weight, lower friction, and enhanced speed capability.
- P4A: Denotes an ultra-precision tolerance class exceeding ABEC 7, ensuring minimal runout and superior rotational accuracy.
- DGA: Specifies a Universal Matchable (SU) arrangement. Two bearings are pre-loaded in a "back-to-back" (DB) configuration for maximum system rigidity.
71914 CE/HCP4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The universal matchable (SU) design, where two bearings are supplied as a pre-loaded set, creates an exceptionally stiff bearing system capable of handling significant combined loads and moments.
Superior High-Speed Performance: The combination of a lightweight phenolic cage, hybrid ceramic balls, and a 15° contact angle allows for a very high limiting speed of 24,000 rpm, reducing centrifugal forces and operational temperatures.
Precision & Longevity: Manufactured to P4A tolerance standards with a chrome steel ring and ceramic balls, this bearing ensures minimal vibration, extended service life, and consistent performance in demanding conditions.
