Helical Gears For High Speed Applications

​HM Manufacturing is a leading manufacturer of custom helical gear systems used for power transmission assemblies.  All HM Manufacturing helical gear products are made in the USA.

​We specialize in manufacturing custom ratchet gears that are made to order and are often asked to add features to many standard style parts. We’re committed to ensuring your projects are done accurately, efficiently and on budget.

​Helical gears are similar to spur gears.  If your operation exceeds 1000 feet per minute then helical gears are your best choice for this power transmission application. Helical gears have a 45° helix angle.

If you require a special size, torque requirement, life span or special features, we will manufacture your custom helical gears based on your drawings or damaged parts sent to our facility. You can specify your custom helical gear material types made of aluminum, steel, bronze, cast iron, delrin or stainless steel.
