FDDC Series
FDDC Series
FDDC series ball screw is a common precision transmission element, widely used in automation equipment, machining and robotics.
FDDC series ball screw adopts advanced processing technology, such as grinding and rolling, to ensure high-precision thread and ball contact surface.
Since the contact between the ball and the screw is rolling friction, the friction coefficient is low and the transmission efficiency is high, reaching more than 90%. There is less energy loss during the transmission process, which helps to improve the overall performance of the system.
FDDC series is designed with a large load capacity in mind, suitable for bearing high axial and radial loads.
Product features
√Low noise, the ball screw produces less noise when working
√During installation and use, the FDDC series ball screw can achieve a certain degree of self-centering ability
√Can achieve high-precision positioning, and the gap between parts is very small
√Use rolling friction instead of sliding friction to significantly reduce friction loss
√Precision manufacturing and reasonable lubrication design
√Can withstand large loads and is suitable for heavy-load applications
√Easy to refuel and clean, reducing the difficulty of user maintenance

Ball screw seal
-
Steel belt casing
Made of metal material (usually steel), it has high strength and wear resistance.
It is widely used in industrial machinery, CNC machine tools and other places that require high strength and wear resistance.
-
Telescopic casing
Made of flexible materials (such as rubber or plastic), it is stretchable and flexible.
Suitable for equipment that requires frequent movement or adjustment, such as automation equipment and robots.
-
Folding casing
Usually made of multiple layers of material (such as cloth, rubber, etc.) with a folded design.
Commonly used in machine tools, automation equipment and other occasions where the lead screw needs to be protected.
