NemaTRUE™

NemaTRUE™ Planetary Gearheads

In addition to the standard NEMA frame sizes, the NemaTRUE is now available in three new metric sizes (60, 90 and 115mm) and has been upgraded with the innovative Micron® RediMount system from Thomson. Thomson Micron now brings you a True Planetary, RediMount compliant gearhead that is an economical solution for your application.  The NemaTRUE has many ratios in stock for immediate delivery through the Thomson Micron Gearhead Express program.

Thomson offers two technologies with most of its TRUE planetary gearheads:
• RediMount™ Motor Mounting System for easy, error free, and quick connection
• PowerTRUE™ 90 Technology, a unique tooth design for higher torque density


Let Thomson Help You Make Your Selection!

Micron MOTIONEERING®, Thomson’s gearhead sizing, selection, and pricing tool can help you size gearheads to high precision motion control applications which require a high torque to volume ratio, high torsional stiffness, and low backlash.
