The FF ball screw is a single flange nut ball screw which provides quiet, smooth running and efficient performance. With small nut installation dimensions, it is great for use in situations requiring small, medium leads, and low, medium speeds. Designed to accommodate applications in various fields, the ball screw is widely used in industrial equipment, precision instruments, precision CNC machine tools, and more.

NOTE
1. KC is the theoretical calculation value when preload Fp is 0.1Ca and axial load F is 0.3Ca.
2. When axial load F is not equal to 0.3Ca.
KC=K(F/0.3Ca)1/3
In formula, K is rigidity value shown in Table.
3. The normal working environment temperature for FF type ball screw is ±60℃.

As a major ball screw manufacturer and supplier based in China, YiGong offers a broad range of products that includes convex linear motion spline, linear motion bushing, radial linear guideway, X-Y axis CNC worktable, and much more.
