FSDC Series
FSDC Series
FSDC series ball screw rods use precision machining technology to ensure high positioning accuracy and repeatability. Since balls are used as the transmission medium, the friction coefficient is low, which can effectively reduce energy loss and improve transmission efficiency.
FSDC series ball screws use high-strength materials and surface treatment technology to enhance wear resistance and extend service life.
A variety of diameters and pitches are available to meet different application requirements.

Accuracy level
According to GB/T17587.3-1998 (same as ISO 3408-3:1992) standard: the accuracy of ball screw pair is divided into seven levels, 1~7, with level 1 being the highest.
Ball screw rod material
| Material | Grinding Grade | Rolling Grade | Heat Treatment Method |
| Screw | 50CrMo4 | S55C | High frequency quenching HRC58~62° |
| Nut | SCM420H | SCM420H | Carburizing treatment HRC58~62° |
Braking device
Since ball screws do not have a self-locking function, especially when installed vertically, a braking device must be set to prevent the load from sliding down. Common braking devices include
- Electromagnetic brake: The electromagnetic brake applies braking force through electromagnetic force, usually automatically activated when the motor stops, ensuring that the screw remains in the current position.
Quick response, suitable for occasions requiring rapid braking. - One-way overrunning clutch:
The one-way overrunning clutch allows the screw to rotate freely in one direction, and locks in the reverse direction to prevent the screw from reversing.
Effectively prevents the load from sliding down due to gravity, suitable for applications that need to maintain position.
