Planetary screw assemblies from Bosch Rexroth

We are your supplier for planetary screw assemblies from our partner Bosch Rexroth.

The planetary screw assembly (PLSA) is a complete cylindrical screw drive with planetary screws as rolling elements. It is used to convert a rotational movement into a lateral movement, or vice versa. Although the elementary function of a planetary screw assembly is simple to describe, in practice it encompasses a variety of different designs and requirements.

Planetary screw assemblies are designed to transfer large amounts of force, and are some of the biggest components in the screw drive portfolio. Planetary screw assemblies are screw drives in which thread rolls act as rolling elements (planets, for short) rotating in a threaded nut with two circles of holes around a specialized threaded spindle, causing the nut to move in a linear fashion along the spindle.

Advantages of a planetary screw assembly:

  • Consistent function thanks to the synchronised planets
  • Very quiet running design
  • High processing speeds
  • Large number of contact points
  • High load rating
  • Highly effective
  • Long service life
  • Compact design
  • High force density
  • Effective, stripping seal
  • Low lubricant consumption
  • Pre-tensioned units available
  • Good positioning and repeat precision

We would be happy to help you select and design the right drive for your needs.
