More and more industries are switching to planetary roller screw drives, benefiting from their high load carrying capacity, easy integration, control, and environmental compatibility.

ihb offers the widest range of planetary roller screw drives for the most demanding applications.

Thanks to state-of-the-art machinery, SKF can offer planetary roller screw drives in a wide range of diameters, from very small to very large, and with a wide selection of pitches.

FEATURES AND BENEFITS
-Length up to 8,700 mm (longer lengths available on request)
-Standard pitch accuracy G5
-High speed depending on nominal diameter (example: 3,300 rpm for threaded drives with a nominal diameter of 48 mm, possibly higher for smaller spindles, please contact SKF directly)
-Optional stainless steel design
-Optional scrapers
-Optional spindle bearing units
-High load carrying capacity and long service life
-Planetary roller concept, without roller recirculation, for high operational reliability, low noise level, and high rotational capacity
-Synchronization of the rollers by means of internally toothed rings, resulting in outstanding performance in applications with frequent direction changes
-Guided rollers for even circumferential load distribution
-No speed fluctuations during direction changes
-Axial play or axial play elimination on request
-Large pitches up to 42 mm for high linear speeds
-Very small pitches from 2.00 mm, for combining high positioning accuracy with high load capacity, high rigidity, and high speeds
-High axial rigidity
-Easy removal of nuts from the spindle, if necessary
-Can be operated in contaminated environments with minimal loss of performance
-Special pitches and left-hand pitches available without any problems
-Minimal torque requirements
-Increased robustness and reliability due to the absence of small components
-Customized designs available
