Crossed Axis Gearboxes
Helical gearboxes are the most common type of gearbox for vehicle and equipment transmissions. Also called crossed axis gearboxes, these devices can generate large amounts of thrust, using bearings to support the thrust load. When mounted to perpendicular shafts, helical gearboxes can be used to adjust the rotation angle by 90°.
Ondrives.US has been designing, engineering, and manufacturing high performance crossed axis helical reduction gearboxes for decades. Our reliable, high performance E Series right angle helical gear boxes are available in numerous sizes and configurations to meet your application requirements. E Series 90 degree helical gear boxes deliver output torque values as high as 62 Nm, with minimal backlash.

Precision 90 Degree Gearboxes
Our compact crossed axis gearboxes produce an output at 90° from the input, and are manufactured with anodized aluminum housings, hardened alloy steel input gears, and hardened alloy steel or aluminum-bronze output gears (varies by model). Precision manufacturing ensures superior helical gearbox performance and reliable service in even the most demanding applications.
Our E Series right angle helical gear boxes (E and EA models) are available with a variety of gear ratios (1:1 to 40:1) and input/output shaft sizes, making it easy to find the right model for your needs. All crossed axis gearboxes provide high efficiency (up to 94% at 1,000 RPM) and low backlash (as little as ≤30 arc minutes).
