At Lawler Gear, precision isn’t just a goal—it’s our daily standard. From keyways to splines, every cut, groove, and profile we machine plays a crucial role in ensuring your equipment performs reliably.
Located in Lee’s Summit, Missouri, just outside Kansas City, we provide custom keyway and spline machining services built on over 45 years of expertise in precision gearing and component manufacturing.
Whether you need a straightforward keyway or a complex multi-tooth spline, our experienced machinists use advanced tools and technology to ensure a perfect fit, smooth operation, and long-term durability.
Keyways and splines might seem like small components, but in the world of industrial gears and rotating equipment, they’re essential. They ensure proper torque transfer, alignment, and mechanical connection between components, which means precision matters at every step.
At Lawler Gear, we use a range of cutting, broaching, and keyseating equipment to create precise keyways and splines for shafts, gears, pulleys, and other mechanical parts. Our process combines decades of machining experience with modern CNC controls and inspection systems to achieve exacting tolerances on every job.
We understand that no two applications are exactly alike. That’s why we tailor every cut to your specifications; whether that means a single keyway on a custom shaft or a multi-spline configuration for high-performance machinery.
We’ve worked with countless customers across industries who rely on us for tight-tolerance, long-lasting results. Every keyway and spline we machine is backed by the same commitment to accuracy, consistency, and craftsmanship that defines our gear manufacturing and rebuilding services.
We approach every project with the same attention to detail and craftsmanship that defines all Lawler Gear services. Here’s how our process works:
We begin by reviewing your part drawings, specifications, and intended application. Our team works with you to confirm dimensions, tolerances, and material needs before machining begins.
Using advanced broaching, slotting, and keyseating equipment, we create keyways and splines that meet exact depth, width, and geometry requirements. Whether cutting internal or external splines, we maintain consistent precision throughout every pass.
Quality assurance is central to everything we do. Each finished component undergoes thorough measurement and verification using precision inspection tools, including our Zeiss Contura G2 CMM. We confirm that every detail, from tooth profile to spacing, meets your specifications.
Once machining and inspection are complete, parts are cleaned, finished, and prepared for prompt delivery. We take pride in delivering components that fit perfectly the first time and perform reliably for years to come.
At Lawler Gear, we support projects at every stage—from concept and prototype to full-scale production. Our team works closely with you to refine designs, recommend materials, and optimize performance based on your application.
Whether you’re developing a new system or improving an existing one, we’re here to help bring your vision to life with precision and reliability.
For more than four decades, Lawler Gear has built its reputation on precision, reliability, and service. Every keyway and spline we produce reflects our dedication to doing the job right—from careful setup to final inspection.
Our customers know they can trust us to deliver parts that fit perfectly, perform flawlessly, and stand the test of time. That’s why manufacturers and operators throughout Kansas City and beyond continue to rely on Lawler Gear for keyway and spline machining services they can count on.
When accuracy matters (and it always does), partner with the experts at Lawler Gear. From custom splines to standard keyways, we’ll ensure every detail meets your exact specifications.
