High-Grade Gearboxes
High-Grade Gearboxes
Anaheim Automation's High-Grade Gearboxes offer a variety of sizes, gear ratios and torque thresholds to match your application's demands. Our High-Grade Gearboxes have been put to the test to provide our customers with the most accurate specifications available. There are four different sizes available ranging from 1.6" to 6.3" in diameter (40mm to 160mm). The variety of diameters allows us to pair motors ranging from NEMA 17 to NEMA 42, with C-Face mounting configurations available. We stock many ratios to match our wide range of motors, but we can make a gearbox to fit any motor in as little as 3 week's time! These High-Grade Gearboxes offer up to 7,080 in-lbs of force with backlash as low as 6 arc-minutes. Ratios are available from 3:1 to 512:1 with torque ratings up to 7,080 in-lbs (113,280 oz-in). Please verify all dimensions when matching a gearbox to a specific motor, as critical dimensions will vary among series and manufacturers.

Note: If you require custom input dimensions or are mounting to a non-Anaheim Automation motor, please fill out our Gearbox Mounting Form and submit it to our sales department.
