Compact inverted roller screws

SKF compact inverted Roller Screws present the technological advantages of planetary roller screws, combined with extra compactness and high carrying capacity associated with smaller leads.

Rotating nut solutions

Ball screw: the nut rotates inside bearings and moves along the fixed long lead screw shaft. The drive motor moves with the nut, so inertia problems, associated with a long rotating shaft, are minimised. This is why a counter-rotation system is necessary at the end of the screw shaft.

  • Ball Screws
  • Roller Screws

End bearings are available for our ball and roller screws in different versions: Axially locating flanged housing with SKF angular contact ball bearings (back to back arrangement); FLBU (for ball screws); FLRBU (for roller screws/ball screws); Fixed Plummer Housing (PLBU) for ball screws; Axially Free Plummer (for ball screws) BUF. 

SKF Linear Ball BearingsGuidance and systems

To provide the best performance for all your needs in guiding, our range is composed of these main products:

Linear Ball Bearings — SKF manufactures linear ball bearings according to DIN ISO 1 and 3. The wide product range includes plain bearings, housings, shafts and additional accessories.

Profile Rail Guides — SKF profile rail guides are accuracy rolling bearings for linear movement, offering a virtually unlimited stroke. All profile rail guides from SKF use modular components — each rail, carriage and/or accessory of the same size can be combined with each other, thus offering easy adaptation to different application demands. SKF offers 4 different types of profile rail guides:

  • Profile rail guides with X-arrangement — The newly launched profile rail guide series LLT features four rows of balls in an X-arrangement. This design provides an equal load carrying capacity in all four main load directions and therefore greater design flexibility since all mounting positions are possible. Moreover, deviations in parallelism and height, which usually occur in multi-axis systems, can be compensated for more efficiently, resulting in reliable and smooth operations under a variety of operating conditions.
  • Profile rail guides with O-arrangement — Ball profile rail guides LLR feature an O-arrangement resulting in a high load-carrying capacity and absorption of high moment loads.
  • Miniature profile rail guides — In response to the market trend for increased performance within a minimum of mounting space, SKF provides a product range by a miniature profile rail guide.
  • Light weight cam-roller guides — Cam-roller guides consist of a rail and carriages with rollers inside. They provide a lightweight construction and ease of installation.
