Super Precision Angular Contact Ball Bearings 71924 ACD/P4ATGA

Super Precision Angular Contact Ball Bearings 71924 ACD/P4ATGA

The 71924 ACD/P4ATGA is a super precision angular contact ball bearing with a 120mm bore and 165mm outer diameter, crafted from durable chrome steel. Its 25° contact angle and extra light preload ensure smooth operation under radial loads up to 35775 lbf.

This open-design bearing spins efficiently at speeds up to 10000 RPM, with a phenolic cage for reduced friction. It comes pre-lubricated and handles temperatures from -30°C to 110°C, making it reliable in varied conditions.

The universal matching set of three bearings allows flexible arrangements (back-to-back, face-to-face, or tandem). Ideal for high-precision applications like machine tool spindles or aerospace systems where accuracy is key.

Weighing 3.45kg, it meets P4A tolerance standards for exceptional performance. Interchangeable with SKF bearings for easy replacement.
