S7013 ACD/HCP4ADGB Bearing Product Overview & Core Advantages
The S7013 ACD/HCP4ADGB is a high-precision double row angular contact ball bearing engineered for demanding applications requiring exceptional rotational accuracy and reliability. This sealed bearing features a light preload (Class B) and is universally matchable (SU), allowing for flexible mounting arrangements in pairs. Its design is optimized to handle combined loads—significant radial loads alongside bidirectional axial loads—simultaneously. The use of ceramic balls and a phenolic cage contributes to its status as a high-speed bearing with superior performance characteristics.
S7013 ACD/HCP4ADGB Bearing Model Code Explained, Specifications & Naming Convention
The S7013 ACD/HCP4ADGB model number provides detailed technical specifications through its suffixes:
- S70: Denotes a high-precision double row angular contact ball bearing series.
- 13: Indicates the bore diameter code (65 mm).
- ACD: Signifies a 25° contact angle and specific internal design.
- HC: Refers to the Hybrid Ceramic construction (Ceramic balls, Steel rings).
- P4A: Identifies the tolerance class P4A, indicating very high dimensional and running accuracy.
- DGB: Denotes a universally matchable (SU) bearing set, where two bearings are supplied as a pre-configured pair.
S7013 ACD/HCP4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides high rigidity, enabling stable support for spindles and shafts under combined radial and axial loads.
- High-Speed Performance: The combination of low-density ceramic balls and a lightweight, robust phenolic resin cage reduces centrifugal forces and friction, allowing for a high limiting speed of 31,000 rpm.
- Precision & Accuracy: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration, which is critical for high-precision machinery.
- Long Service Life & Reliability: The sealed design with pre-applied grease lubrication protects against contamination and provides consistent lubrication within the specified temperature range of -30°C to 110°C, enhancing operational lifespan.
S7013 ACD/HCP4ADGB Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications where precision, speed, and reliability are paramount. Key industries and equipment include:
- Machine Tool Spindles: High-speed machining centers, grinding spindles.
- Precision Industrial Pumps & Compressors
- High-Frequency Motors and Spindles
- Aerospace & Defense Actuation Systems
- Medical Equipment: High-speed dental handpieces, imaging scanners.
