Gear Motions

Gear Motions is an employee-owned, U.S.-based precision gear manufacturer specializing in custom gears, precision ground gears, gearboxes, splines, sprockets, shafts, assemblies, and related power-transmission components.

c specializing in custom gears, precision ground gears, gearboxes, splines, sprockets, shafts, assemblies, and related power-transmission components. With more than 100 years of gear manufacturing experience, Gear Motions provides complete manufacturing support from engineering and prototyping through pre-production, full-scale production, inspection, and finished assemblies.

Gear Motions' Buffalo Operations in Tonawanda, NY combine the capabilities of Oliver Gear and Niagara Gear under one advanced manufacturing facility. These operations provide both large-diameter custom gear manufacturing and high-precision gear grinding, allowing Gear Motions to support applications ranging from small, close-tolerance components to large industrial gearing.

Custom gear capabilities include spur gears, helical gears, pump gears, bevel gears, worm gears, precision ground gears, internal and external splines, sprockets, shafts, gearboxes, assemblies, and replacement or spare parts. Gear Motions can manufacture directly from customer prints or provide engineering assistance to help optimize gear designs for manufacturability, performance, quality, and production.

Manufacturing capabilities include precision gear grinding, gear hobbing, gear shaping, CNC gear cutting, milling, drilling, turning, broaching, keyseating, surface grinding, ID grinding, OD grinding, ID honing, superfinishing, polish grinding, and precision inspection. Customers can utilize Gear Motions for complete turnkey gear manufacturing or individual operations such as gear grinding or gear cutting.

Precision gear grinding is a core specialty. Gear Motions manufactures custom ground spur and helical gears to AGMA quality levels as high as Q15 (DIN 2) and supports both low-volume and high-volume production requirements. Advanced CNC gear grinding equipment with robotic automation provides repeatability, efficiency, and production scalability for demanding applications.

Large gear manufacturing is another important capability of the Buffalo operation. Oliver Gear specializes in custom gearing in low-to-moderate volumes and can manufacture large-pitch and large-diameter gearing up to approximately 10 feet in diameter, providing solutions for heavy industrial machinery and equipment applications.

Spline manufacturing capabilities include both internal and external splines, including involute splines, parallel key splines, and serrations. Gear Motions can manufacture splines through processes including broaching, shaping, milling, hobbing, and grinding depending on the component and application.

Quality and inspection capabilities include climate-controlled inspection laboratories and advanced gear inspection equipment capable of measuring lead, involute profile, pitch variation, runout, size, surface characteristics, and total composite. Additional inspection technologies include CNC gear analyzers, CMMs, optical comparators, profilometers, hardness testing, and Nital Etch testing.

Gear Motions serves OEMs and manufacturers across industrial equipment, machinery, pumps, compressors, blowers, automotive, aerospace, defense, medical equipment, printing and packaging, material handling, automation, and other industries requiring reliable precision gearing and power-transmission components.
