S7013 ACD/P4ATBTC Bearing Product Overview & Core Advantages
The S7013 ACD/P4ATBTC is a precision angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This triplex back-to-back (TBT) matched set delivers superior performance under combined radial and axial loads. Manufactured to P4A tolerance class and featuring a phenolic cage, it is engineered for high-speed operation and reliable service in precision machinery. Its sealed design with pre-applied grease ensures long-term performance with minimal maintenance.
S7013 ACD/P4ATBTC Bearing Model Code Explained, Specifications & Naming Convention
The model code S7013 ACD/P4ATBTC provides detailed technical specifications:
- S7013: Basic bearing series and size designation (65mm bore, 100mm OD).
- A: Denotes a 25° contact angle, optimized for high axial load capacity.
- CD: Indicates a Moderate (Class C) preload applied to the bearing set.
- P4A: Specifies a very high precision tolerance class for superior running accuracy.
- TBT: Identifies the bearing as part of a Triplex Back-to-Back matched arrangement of three bearings.
- C: Specifies the use of a phenolic resin cage, ideal for high-speed applications.
S7013 ACD/P4ATBTC Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The triplex back-to-back arrangement creates an extremely rigid bearing system capable of handling significant combined loads and moment loads, making it ideal for applications requiring high positional accuracy.
- High-Speed Performance: The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 31,000 rpm, reducing centrifugal forces and operational temperatures.
- Precision Operation: Manufactured to P4A tolerance class with tight dimensional control on the bore diameter, outside diameter, and width, ensuring smooth, quiet, and vibration-free running.
- Sealed and Lubricated for Life: The sealed design effectively excludes contaminants, while the factory-applied grease lubrication supports operation within a temperature range of -30°C to 110°C, offering a maintenance-free solution.
S7013 ACD/P4ATBTC Bearing Typical Application Areas
This high-precision bearing set is ideally suited for:
- Machine Tool Spindles (e.g., high-speed milling and grinding spindles)
- Precision Gearboxes and Transmission Systems
- High-Frequency Motors and Spindles
- Industrial Pumps and Compressors
- Advanced Robotics and Automation Equipment
