Economy Gearboxes
In-Line Planetary Gearboxes
Anaheim Automation offers a high-value Economy In-Line Planetary Gearbox. Don't let our low prices fool you - these are high-quality Planetary Gearboxes, designed to offer you the precision and performance you need, at the prices you can afford. There are four different sizes available, from 2.3" to 7.0" diameter (60mm to 180mm). This can be used for any motor ranging from NEMA 23 to NEMA 42. The gears used in these Economy Gearboxes offer you a reliable, economical choice for your motion control application. There are two different mounting configurations: NEMA Mount and C-Face Mount. There are two backlash classes: Standard and Precision. The choice lets you select the appropriate backlash option for your application. Precision backlash is as low as 5 arc-min maximum. We stock many ratios to match up to our wide range of motors, but we can make a gearbox to fit any motor in as little as 3 week's time! Ratios are available from 3:1 to 1000:1 with torque ratings up to 11,329 in-lbs (181,264 oz-in).

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.
