S7013 ACD/HCP4ADBC Bearing Product Overview & Core Advantages
The S7013 ACD/HCP4ADBC is a precision duplex angular contact ball bearing designed for applications demanding exceptional rigidity and rotational accuracy. This matched back-to-back (DB) arrangement is preloaded to Moderate / Class C, providing superior stability and stiffness. Its construction, featuring a phenolic cage and ceramic balls, is optimized for high-speed operation and the ability to handle combined radial and axial loads simultaneously. As a sealed and pre-lubricated unit, it offers reliable, long-term performance in demanding environments.
S7013 ACD/HCP4ADBC Bearing Model Code Explained, Specifications & Naming Convention
The model suffix S7013 ACD/HCP4ADBC provides detailed technical specifications:
- S7013: Basic bearing series designation, indicating a 65mm bore, 100mm OD, and 36mm width.
- AC: Angular Contact design with a 25° contact angle.
- D: Signifies a Duplex (two-bearing) set.
- DB: Specifies the Back-to-Back mounting arrangement.
- HCP4A: Denotes the high-precision P4A tolerance class and the use of a phenolic cage.
- Sealed: The bearing is equipped with integral seals for contamination protection.
- Preload C: Indicates a moderate preload for enhanced rigidity.
S7013 ACD/HCP4ADBC Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The duplex back-to-back (DB) arrangement with a moderate preload creates a highly rigid bearing system that effectively resists moment loads and maintains precise shaft positioning.
- Superior High-Speed Performance: The combination of a lightweight phenolic cage and low-density ceramic balls reduces centrifugal forces, enabling a high limiting speed of 32,500 rpm and lower operating temperatures.
- Excellent Load Capacity: Engineered with a 25° contact angle, this bearing is capable of supporting significant combined loads (radial and axial), with a dynamic load rating of 14,332 lbf and a static load rating of 15,975 lbf.
- Maintenance-Free Operation: The sealed design and factory-applied grease lubrication protect against contaminants and provide long-term, maintenance-free service within a temperature range of -30°C to 110°C.
S7013 ACD/HCP4ADBC Bearing Typical Application Areas
This high-precision, high-speed bearing is ideally suited for:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Equipment
- High-Performance Pumps and Compressors
- Aerospace & Defense Systems
