S7013 ACB/HCP4ADGA Bearing Product Overview & Core Advantages
The S7013 ACB/HCP4ADGA is a precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This sealed, universally matchable bearing is designed to accommodate combined loads—simultaneously handling significant radial and axial forces. Its construction with a ceramic ball and phenolic cage enables superior high-speed performance and operational stability. With a P4A super precision tolerance class and extra light preload, it delivers the high rigidity and rotational accuracy essential for advanced machinery.
S7013 ACB/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACB | Angular Contact Bearing, 25° contact angle. |
| HCP4A | Indicates P4A super precision tolerance class and specific internal design for high accuracy. |
| DGA | Specifies the universal matching (SU) arrangement, allowing two bearings to be mounted in either a back-to-back or face-to-face configuration. |
S7013 ACB/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and universal matchable feature enable the bearing to withstand combined radial and axial loads from both directions, providing a rigid and stable shaft support system.
- Superior High-Speed Performance: The combination of lightweight ceramic balls and a phenolic resin cage significantly reduces centrifugal forces and friction, allowing for a high limiting speed of 32,500 rpm.
- Precision & Longevity: Manufactured to P4A tolerance class with an extra light preload, this bearing ensures minimal runout and vibration for ultra-precise applications. The integral seals protect against contamination, while the pre-applied grease lubrication offers reliable operation within a temperature range of -30°C to 110°C.
S7013 ACB/HCP4ADGA Bearing Typical Application Areas
This precision bearing is ideally suited for high-performance machinery where speed, accuracy, and reliability are paramount. Key applications include:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Aerospace & Defense Systems
