Super Precision Angular Contact Ball Bearings S71916 ACB/P4A

Super Precision Angular Contact Ball Bearings S71916 ACB/P4A

The S71916 ACB/P4A is a super precision angular contact ball bearing with an 80mm bore and 110mm outer diameter, crafted from durable chrome steel. Its compact 16mm width makes it suitable for space-sensitive applications.

With a 25° contact angle, it handles both radial and axial loads efficiently, supporting up to 3330 lbf dynamically. It operates smoothly at high speeds, reaching up to 14,000 RPM, and performs reliably between -30°C and 110°C.

The sealed design keeps lubrication intact, reducing maintenance needs, while the phenolic cage ensures quiet and stable operation. Its P4 tolerance class (ABEC-7) guarantees exceptional precision for demanding tasks.

Ideal for high-precision machinery like CNC spindles or robotics, this bearing is interchangeable with SKF models. Weighing just 0.4kg, it balances lightweight design with robust performance.
