E40-RH 20Nm 40mm-Centres
Crossed Axis Helical Gearboxes
Crossed Axis Helical Gearboxes
Ondrives manufactures precision crossed axis helical gearboxes for applications requiring compact design, smooth torque transmission, and efficient motion transfer at 90°. These gearboxes use helical gears with axes that cross but do not intersect, allowing high efficiency and quieter running compared to traditional right-angle gearing.
Key Features
Torque capacity up to [66Nm]
Centre distances from [e.g. 20 mm to 80 mm]
Right-hand and left-hand helix options
Low backlash for precision control
Manufactured in the UK under ISO 9001:2015 and AS9100 Rev D certification
Applications
Crossed axis helical gearboxes are widely used in instrumentation, automation equipment, robotics, aerospace systems, and test rigs where reliable right-angle transmission is required without the bulk of a worm or bevel gearbox.
Related Products
See our Wormwheel Gearbox Reducers for alternative compact right-angle drives.
Explore Spiral Bevel Gears for intersecting shaft arrangements.
Pair with Shaft Couplings and Bearings for complete motion assemblies.
Why Ondrives
With over 60 years of gear design and manufacturing expertise, Ondrives specialises in custom gearbox solutions. Our in-house CNC machining, gear grinding, and precision inspection guarantee performance and repeatability, even for critical aerospace and defense applications.
