7016 ACD/P4ADBG53 Bearing Product Overview & Core Advantages
The 7016 ACD/P4ADBG53 is a precision angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This duplex back-to-back (DB) arrangement provides superior stiffness and moment load capacity, making it ideal for high-precision spindles and machinery. Manufactured to P4A tolerance class, it ensures minimal runout and consistent performance under combined radial and axial loads. The preloaded matched set eliminates internal clearance, delivering immediate high-rigidity support for enhanced operational precision and dynamic response.

7016 ACD/P4ADBG53 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex back-to-back configuration creates a rigid bearing system that effectively resists moment loads and combined loads. With a 25° contact angle and 20 chrome steel balls (14.288 mm diameter), this bearing delivers exceptional radial dynamic load rating of 22,725 lbf and static load rating of 26,100 lbf.
Precision Performance: Manufactured to P4A tolerance class with tight dimensional tolerances (bore/OD: -0.004mm to 0), this bearing ensures minimal vibration and precise rotational accuracy. The phenolic resin cage provides excellent dimensional stability and reduced friction at high speeds.
High-Speed Capability: The optimized design and phenolic cage enable operation at limiting speeds up to 28,000 rpm, making it suitable for high-speed machining applications. Pre-applied lubrication ensures immediate operation and reliable performance across the temperature range of -30°C to 110°C.
