Super Precision Angular Contact Ball Bearings 7044 ACD/P4ADGA

Super Precision Angular Contact Ball Bearings 7044 ACD/P4ADGA

The 7044 ACD/P4ADGA is a super precision angular contact ball bearing with a 220mm bore and 340mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 117000 lbf and operates smoothly at speeds up to 6300 RPM.

Its 25° contact angle and universal matching design allow flexible arrangements like back-to-back or face-to-face. The phenolic cage ensures durability while keeping the bearing lightweight.

With an extra light preload (Class A), it’s ideal for high-precision applications like machine tool spindles or robotics. The open design simplifies lubrication, and it works in temperatures from -30°C to 110°C.

Weighing 32.1kg, this bearing comes in a matched set of two for balanced performance. Compliant with P4A tolerance standards, it’s interchangeable with SKF models for easy replacement.
