Cold Rolled Spur Gears: Stock & Custom
Request a Quote
Grob Inc. utilizes a process known in the industry as “Grob Rolling,” which cold forms gear and spline-like forms on accurately ground bars. This process was pioneered by Ben Grob in 1951 to increase strength and durability with virtually no waste while producing an extremely smooth surface finish.
One of the components produced by this revolutionary process is a spur gear. Spur gears are cylindrical-shaped toothed components used in industrial equipment to transfer mechanical motion and control speed, power, and torque.
Grob Inc.’s spur gears are manufactured using our own tooling, which allows us to fabricate cold-rolled spur gears that meet the exact specifications across a wide range of industrial applications, whether standard or customized.
Our Spur Gear Manufacturing Capabilities
The capabilities of Grob Inc. spurs are numerous due to our innovative and customized process that allows us to create a product that is superior in quality and specific in customization for each project.
Grob’s long bar lengths of spur gear stocks allow you to cut or machine gear your steel spur gear to whatever length is needed for a particular project, creating the flexibility necessary for a wide variety of spur gear applications. With unmatched customization capabilities, we can offer smaller diameters in lengths up to 6 feet, and larger diameters up to 12 feet. We pride ourselves on our ability to offer non standard stock lengths not offered by most of our competitors.

Advantages of Spur Gears from Grob Inc.
Because of our commitment to excellence, the experts at Grob developed our own methods for cold forming gears, splines, shafts, bushings, and a variety of other metal parts. The Grob Rolling process increases the strength of the spur gear by rearranging the grain structure of the material over the entire tooth profile. In doing so, the material is displaced rather than removed. The result is a strong and durable product with a smooth surface finish.
Other advantages of spur gears include simplicity in design, high-precision constant speed drive, reliability, cost-effectiveness, and efficiency.
