Thomson Linear Motion Optmized
Viti a sfere
L'azionamento della vite a sfera è un gruppo che converte il movimento rotativo in moto lineare (o viceversa). Si compone di una vite e un dado a sfere raggruppati in un gruppo con cuscinetti a ricircolo di sfere. L'interfaccia tra la vite a sfere ed il dado è costituita dalle sfere dle cuscinetto che rotolano nelle scanalature accoppiate. Con gli elementi volventi, la vite a sfere ha un bassissimo coefficiente di attrito ed è in genere ha un efficacia superiore al 90% . Le forze trasmesse sono distribuite su un gran numero di cuscinetti a sfera, dando un basso carico relativo per sfera.
Standard Ball Screws
Custom Ball Screw Options
Ideal for high-precision, high-load applications, metric and inch ball screws are manufactured to the highest standards to translate rotational motion to linear motion with minimal internal friction.
Why Thomson Ball Screws?
Not all precision ball screws are created equal. At Thomson, our careful attention to design, quality, materials, manufacturing and application support has set us apart from the competition and created an ideal recipe for success that has lasted for decades.
When standard Thomson ball screws don’t meet your exact specification requirements, our engineering experts can help customize a solution for your application. Whether it’s one or a large quantity, a simple component modification or complex assembly, our custom capabilities can meet your needs and improve your machine’s performance.

Inch vs. Metric Ball Screws: Are You Asking the Right Questions?
Because ball screws are available in both inch and metric dimensions, designers sometimes begin the specification process by selecting a product family based on the unit of measure. This decision may prematurely exclude the ideal product for the application and lead to significant losses in time, labor and expense. This article explains how sizing and selection questions centered on performance – instead of product monikers – can lead to more efficient linear motion designs.

Roller screws have been promoted as the only technology of choice for handling large loads when size is a constraint. But in actuality, advances in ball screw technology have now enabled the capability to support high-load applications as well. This is important because a high-load ball screw is typically less than half the cost of a comparable roller screw at equivalent performance points.

Used in large-scale production applications that involve continuous lifting operations but still require a human touch, collaboration robots (cobots) are gaining popularity. A French cobot maker has developed a solution that uses ball screw and cable actuators instead of gears, setting a new benchmark for cobot efficiency and safety.
