Super Precision Angular Contact Ball Bearings S71918 ACEGA/P4A

Super Precision Angular Contact Ball Bearings S71918 ACEGA/P4A

The S71918 ACEGA/P4A is a super precision angular contact ball bearing with a 90mm bore and 125mm outer diameter, crafted from durable chrome steel. Its 25° contact angle efficiently handles both radial and axial loads, making it versatile for high-precision applications.

Designed for extra light preload (Class A), it ensures smooth operation at speeds up to 15,000 RPM. The sealed design keeps grease in and contaminants out, reducing maintenance needs.

With a phenolic cage and 24 high-quality steel balls, it offers reliable performance in temperatures from -30°C to 110°C. Its P4A tolerance class guarantees exceptional accuracy for demanding setups.

Ideal for machine tools or spindle drives, this bearing can be paired back-to-back, face-to-face, or in tandem. Weighing 0.54kg, it balances strength and precision for industrial use. Interchangeable with SKF models for easy replacement.
