7001 CE/HCP4ADBAGMM2 Bearing Product Overview & Core Advantages
The 7001 CE/HCP4ADBAGMM2 is a premium duplex angular contact ball bearing designed for applications demanding exceptional precision and performance. This matched set features a back-to-back (DB) arrangement, providing superior rigidity and the ability to withstand combined loads—significant radial and bidirectional axial loads simultaneously. Manufactured to an ultra-precise P4A tolerance class and utilizing ceramic balls, it is engineered for high-speed operation and extended service life in demanding environments.
7001 CE/HCP4ADBAGMM2 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7001 | Basic bearing series, defining the standard dimensions (12mm bore, 28mm OD, 16mm width). |
| CE | Indicates the use of ceramic (hybrid) balls, offering reduced friction, higher speed capability, and non-conductive properties. |
| HCP4A | Specifies the tolerance class P4A (higher than ABEC 7) and a 15° contact angle, ensuring extreme running accuracy and optimized axial load capacity. |
| DB | Denotes the Duplex Back-to-Back mounting arrangement, which provides high moment rigidity. |
| AGMM2 | Signifies a matched set of two bearings with specific preload (Extra light / Class A) for consistent, predictable performance. |
7001 CE/HCP4ADBAGMM2 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex back-to-back (DB) arrangement creates a rigid bearing system that effectively resists moment loads and supports substantial combined radial and axial loads.
Superior High-Speed Performance: The combination of ceramic balls (lower density and reduced centrifugal force) and a lightweight phenolic resin cage enables a very high limiting speed of 100,000 rpm, making it an ideal high-speed bearing.
Ultra-Precision: Manufactured to a P4A tolerance class with extremely tight bore and outside diameter tolerances, this bearing ensures minimal runout and vibration for applications requiring the highest levels of accuracy.
Optimized Preload: The bearings are supplied as a pre-matched set with an extra light (Class A) preload, eliminating internal clearance and providing immediate, precise rotational performance upon installation.
