Helical Racks
Helical rack components for linear motion systems.
Crossed Helical Gears
Crossed-axis helical gear sets for non-parallel shaft drives.
Custom Helical Gears
Non-standard helical gears manufactured from customer drawings.

Frequently Asked Questions
What is the advantage of helical gears over spur gears?
Helical gears provide smoother engagement, higher load capacity and quieter operation due to the gradual tooth contact from the angled teeth.
Can you control the helix angle?
Yes. The helix angle is machined to drawing specification. Please provide the required helix angle on your drawing.
Can you produce double helical (herringbone) gears?
Yes. We can produce herringbone gears with opposing helix angles for axial thrust cancellation.
Do you offer gear grinding for helical gears?
Yes. Gear grinding is available for high-precision applications requiring smoother tooth surfaces.
