In everyday life, it's often the most reliable technology that goes unnoticed because it simply works. Whether it's a robotic limb, a high-speed assembly line, or a life-saving surgical tool, the internal mechanics tend to operate flawlessly. KHK USA Inc., a Mineola-based company, provides the specialized components that fuel this consistency. Offering high-grade metric gearing to North America for use across robotics, packaging equipment, medical devices, and gantry systems, the company champions technical mastery and customer-focused partnership.
Founded by Brian Dengel, the company operates as North America's arm of Kohara Gear Industry, a Japanese manufacturer with roots dating back to 1935. Dengel points to its lineage as a testament to the scale and structure it has upheld, along with an almost evangelical belief in performing extraordinarily well. With an expansive stock of metric gears available off the shelf, Dengel highlights how each item is paired with 3D CAD models and technical specifications ready for immediate integration into engineering workflows.

"Most of our competitors are like a supermarket, with pulleys, belts, sprockets, and bearings. We just bring gears," Dengel says. The numbers, he notes, are hard to argue with. Metric gearing still represents only about 21% of the US market, and KHK USA has carved out a definitive space in that margin.
"The remaining 79% continues to rely on inch-based systems, but we've made a deliberate choice to stand entirely within that minority, building a specialization across multiple product categories that are hard to match," he explains.
The company's product portfolio spans spur gears, helical gears, bevel gears, worm wheels, gear racks, and each exists as part of a deeply indexed catalog designed to eliminate friction in the sourcing process. According to Dengel, a majority of KHK's business comes from these stock products, which, in his view, reinforces how often engineers can skip custom manufacturing entirely.
"Customers don't have to spend weeks chasing a custom quote or designing the product because it is already pre-designed. They visit our website, grab a model, drop it onto their assembly, and they can be done before lunch," Dengel says. Time, in this context, becomes a design variable.
The company's "parent-child" framework adds another layer to that efficiency. Dengel explains how a base gear, considered the "parent," can be modified into a "child" product through machining processes like bore enlargement, keyway broaching, or tapped holes, all within a tight deadline. He says, "A request placed on a Monday can result in a finished, application-ready component by the following week."

According to Dengel, KHK's factory-direct program leverages its relationship with its Japanese parent company to ship parts internationally with efficiency. "Orders placed in the US can arrive at a customer's facility in less than a week," he adds.
Still, speed and availability would mean little without guidance. Although gear selection seems straightforward, Dengel argues that minor errors can create significant, system-wide repercussions. He notes that their clientele spans from highly regulated medical manufacturers, which require rigorous inspection protocols, to commercial buyers balancing performance with cost restrictions.
"The product is only going to be as good as the poorest quality component in the machinery," he notes. "A lot of what we do is guide customers to something that fits, not just dimensionally, but in terms of tolerance, quality, and cost performance."
Misconceptions are often common in the gear space, particularly around materials and scale. Plastic gears, he argues, carry an undeserved reputation for weakness. He argues that they can match metal counterparts under the right conditions, provided size and design are adjusted accordingly. "People assume a plastic gear can't handle the same load," Dengel says. "But increase the size, and suddenly it can. There's a misunderstanding of scale."

That misunderstanding ties into a broader principle, one that anchors Dengel's perspective on engineering itself. "There's a phrase people like to use: if you can draw it, you can build it. But just because you can draw it, and even build it, doesn't mean it's reliable or accessible," he says.
It's a line that captures the tension between possibility and application, a space where KHK has positioned itself with purpose. Instead of chasing trends, the company prioritizes consistency, catalog depth, and the ability to deliver solutions that work immediately.
Nobody, Dengel acknowledges, wakes up craving a gear. It is, as he puts it, a "need" product, not a "want" product. When machines break, and new designs demand new components, he notes that the pivotal question then is simply who comes to mind first. After years of building a catalog that is as deep as it is precise and a shipping model that turns international logistics into a quick errand, KHK's strategy revolves around being that first name in that moment of need.
"We always want to be top of mind," Dengel says. "Because when the need comes around, that's when it matters."
