S7016 ACD/P4ADGA Bearing Product Overview & Core Advantages
The S7016 ACD/P4ADGA is a high-precision double row angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and rigidity. This sealed precision bearing features a universal matchable (SU) design, allowing two bearings to be mounted in any combination to achieve the required preload. Its primary advantage lies in its ability to simultaneously support substantial combined loads (radial and bidirectional axial loads) with high running accuracy, making it ideal for high-reliability, high-speed machinery.
S7016 ACD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number S7016 ACD/P4ADGA provides detailed technical specifications through its suffixes:
- S70: Denotes a series of high-precision angular contact ball bearings.
- 16: Indicates the bore diameter code (80 mm).
- ACD: Signifies a 25° contact angle and a universal matchable (SU) design.
- P4A: Represents a very high tolerance class (geometric and running accuracy superior to ABEC 7).
- DGA: Indicates the bearing is sealed on both sides and pre-lubricated with grease.
S7016 ACD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial rigidity compared to single row bearings, enabling stable operation under significant combined loads.
- Precision & High-Speed Performance: Manufactured to P4A tolerance class, it ensures minimal runout and vibration. The lightweight phenolic cage and optimized internal geometry contribute to a high limiting speed of 28,000 rpm.
- Sealed & Maintenance-Free Operation: The integral seals (DGA suffix) effectively protect against contamination and retain lubricant, offering long-term, maintenance-free service within the specified temperature range.
- Universal Matchability (SU): Bearings are universally matchable, simplifying installation and preload setting in duplex pairs (back-to-back or face-to-face) without selective mounting.
S7016 ACD/P4ADGA Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Spindles
- Industrial Pumps and Compressors
- Aerospace & Defense Actuators
