Super Precision Angular Contact Ball Bearings 71814 ACDGA/P4

Super Precision Angular Contact Ball Bearings 71814 ACDGA/P4

The 71814 ACDGA/P4 is a super precision angular contact ball bearing with a 70mm bore and 90mm outer diameter, crafted from high-quality chrome steel. Its 25° contact angle efficiently manages both radial and axial loads, making it versatile for various applications.

With a dynamic radial load capacity of 2925 lbf, it handles high-speed operations up to 28,000 RPM smoothly. The phenolic cage ensures durability and reduces friction, enhancing performance.

Designed for extra light preload (Class A), it offers precise movement and minimal vibration. Its open seal type allows easy lubrication, ideal for maintenance-friendly setups.

This bearing is interchangeable with SKF models and comes in matched sets of four for universal mounting options (back-to-back, face-to-face, or tandem). Perfect for precision machinery like spindles or CNC equipment.

Weighing just 0.13kg, it’s lightweight yet robust, suitable for temperatures from -30°C to 110°C. A reliable choice for engineers needing accuracy and durability.
