Gearboxes & Air Motors
Standard Gearbox and Air Motor Models
High quality standards and proven performance have made Ondrives.US a trusted brand in air motor and gearbox manufacturing. All standard models are built for precision and designed with features that improve performance and solve common mechanical challenges. Points to consider while browsing our inventory include ratio, backlash rating, operation, temperature range, operating environment, input and output needs, housing material, and application.
Choose from our categories below to find a gearbox model based on your requirements or use our competitor cross-reference tool to search products based on your existing gearbox’s part number. Our engineers are also available to help you choose a gearbox or air motor based on your specifications and operating environment.
Our newest gearbox in the Ondrives.US product line delivers high-efficiency results in smaller capacity motors. These gearboxes handle heavier load transmission, achieve higher gear ratios, and have an incredibly quiet operation.
Air motors are more convenient and easier to use compared to other power-generating motors. Our piston air motors have a low-maintenance design, resist corrosion, and are compatible with flammable environments, underwater installation, and applications where electromagnetic interference is a design concern.
Compact right angle wormwheel speed reducers produce an output at 90° from the input. 10 space-saving frame sizes are available, with output torques as high as 420Nm.
Crossed axis gear drives produce an output at 90° from the input. These gearboxes feature anodized aluminum housings and hardened alloy steel input gears for durability in challenging applications. Available with gear ratios from 1:1 to 40:1 and torque values up to 62Nm.
Our Bevel T right angle speed reducers feature a shaft that passes through both sides in the form of a “T”. This solid thru-shaft rotates at both ends simultaneously. Also available with a single output shaft. Available in ratios from 1:1 to 24:1.
Our counter-rotating T-style bevel gearboxes feature two output shafts on the same axis and an input shaft at 90° from both; the output shafts rotate in opposite directions.
Also known as parallel shaft gearboxes, spur gear reducer boxes provide an output that is parallel to the direction of the input shaft. Available in gear ratios from 2:1 to 7:1 with torque output up to 850Nm.
Inline reducer gearboxes provide an output that continues in the same direction and on the same plane as the input. We offer a wide range of inline reducers, including spur, Encoder, low-backlash taper, speed increasers, and more. Available in ratios up to 3600:1.
Rack and pinion actuator gearboxes convert rotational motion into linear motion, or vice versa. Our compact designs provide short strokes from 10mm to 30mm.
Our motorized planetary reducers are small, inline devices designed for low backlash performance in speeds up to 3,000 RPM. Slim, compact footprints make them ideal for applications where space is limited.
Many of our other gear reducer styles are available in miniature versions. These ultra-compact gearboxes are precision engineered for superior performance in tight spaces and small-scale applications.
Modified and Custom Gearbox and Air Motor DesignsA wide variety of standard gearboxes and motors makes it easy to find a solution for almost any application. With an in-house team of application engineers, we can also modify or customize any of our standard products to meet your unique specifications. Our team can also reverse engineer obsolete gearboxes or help you find a comparable gearbox within our product line. Contact our application engineers to discuss your custom gearbox application.
