Pulley Stock

Bar stock and ready-to-machine pulley blanks in every common pitch and length.

All Pitches Various Lengths

Timing Belts

Full inventory of synchronous and flat belts from the industry's leading manufacturers.

Gates Belts Neoprene Belts Urethane Belts Kevlar Flat Belts

Flanges & Bearings

Standard and custom flanges to retain belts and complete your drive assembly. Bearings are critical mechanical components that restrict motion to desired paths and reduce friction between moving parts.

Capabilities

Full-service precision machining under one roof

From gear hobbing to broaching and secondary operations, we run a vertically integrated shop so your project stays on time, on spec, and on budget.

Gear Hobbing & Pulleys

Our advanced gear hobbing operations deliver unparalleled consistency, accuracy, and cost-effectiveness for both high-volume production runs and low-volume custom orders. Utilizing modern CNC technology, we achieve tight tolerances and superior surface finishes tailored to your exact specifications.

CNC Turning

Get fast, high-quality, and cost-effective production of custom cylindrical parts. We combine automated CNC turning with live tooling capabilities to produce symmetrical components, complex geometries, and custom threads in a single setup.

CNC Milling

Our high-precision CNC milling services transform raw metal and plastic blocks into complex, custom-engineered components. Utilizing advanced 3-axis and 5-axis milling centers, we deliver rapid prototyping and scalable, cost-effective production runs with micron-level tolerances.

Broaching

High-Volume Efficiency: Broaching's single-pass operation significantly reduces cycle times and per-unit costs for large production runs.

End-to-End Solutions

We support complete part manufacturing, offering secondary operations such as heat treating, plating, anodizing, grinding, EDM and assembly so you get a finished, ready-to-use component.

Assembly & Inspection

We deliver expert assembly for components and finished products across diverse industries. From manual precision fitting to scalable automated processes, our facility is equipped to handle everything from intricate sub-assemblies to large-scale manufacturing runs. Quality is our priority — we employ advanced quality control measures to ensure every assembly meets or exceeds industry standards. Our multi-tiered inspection process protects your supply chain and guarantees optimal functionality.
