Gear manufacturing for small to mid-sized OEMs
Custom and standard gears cut and machined in our Hudson, Ohio shop, in steel, alloy and hardened steel, stainless, brass, bronze, copper, aluminum, cast iron and non-metallic materials.
CNC gear hobbing and CNC gear shaping
We now cut gears in-house on CNC hobbing and CNC shaping machines: hobbing for external spur and helical gears, worm gears, splines and sprockets; shaping for internal gears, internal splines and gears cut close to a shoulder. That means repeatable quality and more control over delivery.
Want the tools and machines rather than finished gears? Our sister company CTI-USA supplies gear hobs, shaper cutters, broaches and Eifco CNC gear hobbing and power skiving machines.
Dependable delivery
Standard lead time is eight to ten weeks, with expediting available for an additional charge. Breakdown service, blanket orders and stocking plans keep your line running.
Technical support
Every Rhino gear is backed by our engineers, who are available to discuss your application and gear requirements.
High quality
Skilled craftsmen, quality materials and premium tooling deliver custom gears that meet or exceed OEM requirements.
Fair price
An efficient workflow, skilled team and fast turnaround make Rhino gears affordable and reliable.
