Super Precision Angular Contact Ball Bearings 7008 ACD/P4AQGC

Super Precision Angular Contact Ball Bearings 7008 ACD/P4AQGC

The 7008 ACD/P4AQGC is a super precision angular contact ball bearing with a 40mm bore and 68mm outer diameter, crafted from high-quality chrome steel. It features a 25° contact angle and is designed for moderate preload (Class C), making it suitable for high-speed applications up to 56,000 RPM.

With a dynamic radial load capacity of 9518 lbf, this bearing handles both radial and axial loads efficiently. The phenolic cage ensures smooth operation, while the open seal design allows for easy lubrication and maintenance.

This bearing is part of a universal matching set of four, compatible with back-to-back, face-to-face, or tandem arrangements. Ideal for precision machinery like spindles or CNC equipment, it operates reliably in temperatures from -30°C to 110°C.

Weighing 0.77kg, it’s a robust yet manageable component for demanding applications. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for convenient replacements.
