Precision Ball Screw Assemblies

Our ball screw assemblies offer a range of cost effective options to meet your linear motion application requirements. The specialised internal recirculation design and optimal pick-up of balls result in smooth operation.

Ball screws from Tectra Automation have several advantages to a typical Acme screw drive, including a higher life expectancy, higher travel speed with no stick-slip effect and an exceptional mechanical efficiency of 98%.

These assemblies achieve a high load rating due to the larger number of balls and a high axial load capacity. It also has several advantages to a typical Acme screw drive including a higher life expectancy, higher travel speed, no stick-slip effect and an exceptional mechanical efficiency of 98%.

As ball screw manufacturers, we offer an extensive range of accessories for ball screw assemblies, including nut housings, pillow block units, bearings, slotted nuts and front lube units.

Ball bearings move along the threaded ball screw shaft, between the shaft and the ball screw nut

Frequently asked questions:

What is a ball screw?

A ball screw assembly converts rotary motion into linear motion (and vice versa), allowing for precision movement with little friction. Ball bearings move along the threaded ball screw shaft, between the shaft and the ball nut. The ball screws are specially designed to withstand high loads, while the ball bearings prevent friction between the ball nut and the screw.

What types of applications use ball screws?

They are used in a wide range of applications, across multiple industries, where they move control surfaces or translate motion. They’re used in aircraft, missiles, automobiles (e.g. in power steering systems), machine tools, robots and precision assembly equipment.

What is the difference between ball and a lead screws?

Both of these are mechanical linear actuators. A ball screw uses ball bearings to minimise friction and enhance efficiency. They are noisier and less rigid than lead screws but can carry a heavier load, are more precise and usually don’t self-lock.

Lead screws, on the other hand, use sliding surfaces which creates high friction. However, they are quieter and cheaper than ball screws and more easily customised.
