Frequently asked questions
Answers to the questions engineers most often ask when specifying a roller screw.
What is a planetary roller screw?
A planetary roller screw converts rotary motion into linear motion using threaded rollers arranged around a central screw shaft. The rollers make line contact with both the screw and the nut, spreading load across many contacts for high capacity and long life.
How is a roller screw better than a ball screw?
Roller screws carry higher loads, achieve finer leads, resist shock and offer longer service life at high duty cycles, because load is shared across many rollers rather than a few point-contact balls.
Which industries do you serve?
We focus on aerospace, defence, robotics and automation, and also supply medical, optics, semiconductor, automotive/EV, energy and research customers.
Do you offer custom roller screws?
Yes. Alongside standard families we design bespoke screws — custom leads, coatings, materials and integrated assemblies — sized to your duty profile.
Can I get CAD files and data tables?
Yes. 2D and 3D CAD models and detailed data tables are available for design-in. Request them from the downloads page or with a specific size enquiry.
What are your lead times?
Lead time depends on family, size and quantity. Standard configurations ship faster than bespoke designs; contact us with your requirement for a delivery estimate.
Where are you located?
Our office is in Chandigarh, India, with manufacturing at Barwala, Haryana.
