High Performance, Low Backlash Speed Reducer Gearbox

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 these speed reducers will deliver years of reliable performance. The housings of these low backlash gearboxes are manufactured from black anodized aluminum, with 303 stainless steel gears and shafts. These materials also exhibit outstanding corrosion resistance, making the SRX Series of in-line speed reducer gearboxes ideal for use in harsh working environments.
