Roller Screws
High Force and Efficient Operation in a
Compact Package
Roller screws (also called planetary roller screws) have precision-ground screw threads that match multiple precision-ground rollers in the nut. These rolling elements transmit force very efficiently. Roller screw components provide more points of contact allowing for higher force capability and longer life. Tolomatic roller screws have a very deep case (surface) hardness and high Dynamic Load Rating (DLR*).
For many years, Tolomatic has manufactured thousands of roller screws per year for actuators and installed them in applications around the world. Tolomatic now offers these roller screws for sale as component parts as well as incorporated in actuators.
Manufactured in the United States using state-of-the-art equipment to ensure strict tolerances and the highest quality standards confirming that each roller screw provides top-tier performance
Tolomatic Planetary Roller Screws:
- Verified and tested extensively in Tolomatic’s research & development lab
- Proven long, reliable life in thousands of demanding applications world-wide
- Configurable stroke lengths
- Allows for smaller, lighter weight designs and machine concepts
- Industry best lead times
