Low Backlash Speed Reducer Gearbox

Encoder applications require an exceptionally high level of precision to ensure proper translation of motion into digital signals. Standard gearboxes often meet requirements for reliable speed reduction but produce gear backlash that impacts accuracy. Low backlash inline gearboxes provide a solution by improving smoothness and positioning accuracy while minimizing motor noise in high speed, high precision applications.

Improve Positioning Accuracy with Low Backlash Gearboxes

Ondrives.US is one of the world’s leading manufacturers of high-performance low-backlash gearboxes. Our SRX Series low backlash inline gearboxes are specially engineered to deliver the precision required for encoder applications. We offer speed reducers in a wide variety of gear ratios and shaft sizes to meet your unique needs.

High-Performance Low Backlash Inline Gearboxes

Ondrives.US’ SRX in-line speed reducers are rated for speeds up to 3,000 RPM. These speed reduction gearboxes have a very low moment of inertia at the input shaft (as low as 0.015 gm-cm2). Two frame sizes are available, with gear ratios from 4.96:1 up to 3,600:1. Low Backlash is maintained at 1.5 arc-minutes or better at any ratio.
Durable materials and quality craftsmanship ensure that low-backlash gearboxes will deliver years of reliable performance. The housings are manufactured from black anodized aluminum, with 303 stainless steel gears and shafts. These materials exhibit outstanding corrosion resistance, making SRX Series low backlash gearboxes ideal for harsh working environments.
