XL Xtrem Load

What Does a High Load Ball Screw Do?

Ball screws play a key role in certain linear actuators, transforming rotational motion into linear motion. This reliably and accurately transmits force to a stationary or moving load.

In these special designs, steel ball bearings surround part of a screw shaft, sealed in that specific space by the ball nut. By reducing contact between each element of the screw assembly, ball screws reduce overall friction. This, in turn, creates high efficiency – much greater than what lead screws (which have a similar design but lack ball bearings) can offer.

Within the XL Extrem product family, Extrem Load ball screws stand out for their high load and high speed tolerances. For example, the IML screw design can reach DN (driving speed value) up to 170,000.

As part of Rollon ball-screw-driven linear actuators, XL Extrem screws contribute to precision accuracy within ±0.005 mm. Coupled with their compact design, that reliable accuracy makes these actuators ideal for injection molding machines, presses, and other industrial automation systems.
