Product Overview and Core Advantages
The 7016 ACD/P4ADBA is a precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This duplex back-to-back (DB) arrangement bearing set is preloaded to Extra Light (Class A) specifications, ensuring minimal axial and radial play for superior system stability. Engineered to handle combined loads with high thrust capacity from both directions, its compact design and P4A tolerance class make it ideal for high-precision, high-reliability machinery where uncompromising performance is critical.
7016 ACD/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
The model number 7016 ACD/P4ADBA provides detailed technical specifications:
- 7016: Basic designation indicating a 80mm bore, 125mm OD, and 44mm width bearing.
- A: Denotes a 25° contact angle, optimized for high axial load capacity.
- C: Indicates the bearing is manufactured from Chrome Steel for high durability.
- D: Specifies a Duplex Back-to-Back (DB) matched set arrangement.
- P4A: The tolerance class, signifying very high precision levels for runout and dimensional accuracy.
- DBA: Confirms the set consists of two bearings matched for back-to-back mounting.
Structural Features and Performance Benefits
- High Rigidity and System Stiffness: The duplex back-to-back (DB) arrangement creates a wide effective spread, significantly increasing moment rigidity and providing exceptional support against complex loading conditions.
- Superior Load Capacity: The 25° contact angle and robust construction enable high radial and bidirectional axial (combined loads) carrying capacity, with a dynamic load rating of 22,725 lbf and static rating of 26,100 lbf.
- Precision High-Speed Performance: The Phenolic cage offers low weight and excellent performance at the high limiting speed of 28,000 rpm, while the P4A tolerance class ensures smooth, vibration-free operation.
- Optimized for Precision Applications: Manufactured to ultra-tight bore and outside diameter tolerances (-0.004mm to 0), this bearing guarantees precise shaft positioning and consistent performance in high-accuracy systems.
