7014 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7014 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Manufactured to the stringent P4A tolerance class, this bearing excels in high-speed operations with a limiting speed of 22,000 rpm. Its universal matchable (SU) design allows for flexible mounting in pairs to support combined loads, handling both radial and axial forces simultaneously. The extra light preload (Class A) ensures smooth, precise rotation with minimal friction, making it an ideal choice for high-performance spindles and precision machinery where reliability is paramount.
7014 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7014 CD/P4ADGA provides detailed technical specifications through its suffixes:
- 7014: Standard designation for a 70mm bore, 110mm OD, 40mm width bearing.
- CD: Indicates a 15° contact angle and universal matchable (SU) design, allowing bearings to be mounted in either a back-to-back (DB) or face-to-face (DF) arrangement.
- P4A: Denotes an ultra-precision tolerance class exceeding ABEC 7, with enhanced running accuracy for spindle applications.
- DGA: Specifies an extra light preload (Class A) for high-speed, low-friction operation.
7014 CD/P4ADGA Bearing Structural Features & Performance Benefits
The 7014 CD/P4ADGA's construction delivers distinct performance advantages:
- High Rigidity & Load Capacity: The optimized 15° contact angle and robust internal geometry provide excellent stability, enabling the bearing to support significant combined loads (Radial dynamic: 18,720 lbf, Static: 20,588 lbf).
- Superior High-Speed Performance: The lightweight, durable phenolic resin cage minimizes centrifugal forces and ensures stable operation at the high limiting speed of 22,000 rpm.
- Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), guaranteeing exceptional running accuracy and minimal vibration.
- Optimized Material Selection: Components made from high-grade chrome steel offer high hardness and wear resistance, contributing to a long operational life under demanding conditions.
