Product description

Ball screw assemblies BSA

Ball screw assemblies are the efficient solution for the precise conversion of rotary to linear motion. Building on our many years of experience and extensive engineering expertise, we have developed a product range that fulfills the most diverse requirements. No matter whether you need very high linear speeds, maximum load ratings, or minimum installed length, you will always find the right solution in Rexroth’s broad manufacturing spectrum. To make sure your application runs with the utmost accuracy and operational reliability, the individual components in our range have been precisely matched to one another, so complete assemblies can be put together efficiently.

Characteristic features

• A wide range of products, suitable for virtually any requirements

• Absolutely uniform and stable functionality

• Particularly quiet running due to optimal ball pick-up and complete recirculation

• High load ratings due to large number of balls

• Short nut length

• Easy installation of the nuts, mounting orientation according to individual specifications

• Adjustable- pretensioned single nuts

• Extensive range comprising various series

• Matching supplementary individual components such as nut housings and end bearings, also as pillow block units, partly prepared for the installation of suitable motor flanges

Planetary screw assemblies PLSA

The planetary screw assembly PLSA is a complete cylindrical screw assembly with planets as the rolling elements. It serves to convert rotary motion into linear motion and vice versa. The basic functioning of a planetary screw assembly is easy to describe, but the range of designs and the requirements for practical applications are many and varied. Planetary screw assemblies are designed to transmit high forces and thus round off the upper end of the screw assembly product portfolio.

Planetary screw assemblies are screw assemblies in which threaded rollers (the planets) are housed in a threaded nut, their ends being lodged in discs with holes arranged around a pitch circle so that they rotate axially parallel to the special threaded screw, causing the nut to move linearly along the screw.

Characteristic features

• Smooth functioning due to the principle of synchronized planets

• Particularly quiet running

• Length Service life

• Compact construction

• High power density

• Pretensioned units available

• High positioning accuracy and repeatability

• Low lubricant consumption
