What is roller screw ?

The roller screw is a linear motion transmission device consisting of a screw, nut and roller.

Its working principle is to drive the nut to move linearly through the rotation of the screw rod, while the rollers roll between the screw rod and the nut to reduce friction and improve transmission efficiency.

Roller screws have the following advantages:

1. High load-bearing capacity: able to withstand large axial loads.

2. High precision: precise linear motion can be achieved.

3. High efficiency: high transmission efficiency.

4. Long life: good wear resistance and long service life.

5. Good stability: smooth movement, low vibration and noise.

Roller screws are widely used in the following fields:

1. Machine tool industry: used in CNC machine tools, milling machines, etc.

2. Industrial automation: such as robots, automated production lines, etc.

3. Precision measuring instruments: ensure the accuracy and stability of measurement.

4. Aerospace field: equipment with high requirements on accuracy and reliability.

When designing and using roller screws, the following factors need to be considered:

1. Accuracy requirements: Determine the required accuracy level according to the specific application.

2. Load capacity: Ensure that it can withstand the load during work.

3. Speed ​​range: Adapt to different movement speeds.

4. Environmental conditions: such as temperature, humidity, etc.

5. Cost factors: comprehensive consideration of performance and price.
