At Polgain, we specialise in the design and manufacture of precision-engineered camshafts and components that support industries across the world.

As the UK’s only independent cam manufacturer, we are proud to blend heritage with innovation, offering bespoke solutions that meet the most demanding requirements.

Our history dates back more than a century, originating as Zephyr Cams. From crafting cams for the Zephyr motor car to producing pistons used in the very first transatlantic flight, our roots are firmly embedded in engineering excellence.

Today, under the ownership of Saint Vincent Holdings Group, we combine that proud legacy with the resources and stability of a global partner, while maintaining the agility and craftsmanship of a specialist manufacturer.

We serve a wide range of industries including motorsport, power generation, packaging, bottling and pharmaceuticals. Our capabilities stretch from CNC batch production to specialist coatings, heat treatments and material inspections, ensuring quality and reliability at every stage. Whether the project is large scale or highly niche, our team has the expertise to deliver solutions that perform under pressure.

Quality underpins everything we do. As an ISO 9001:2015 accredited company, we work to rigorous standards and ensure that every component meets the exacting specifications of our customers. Our reputation is built on long-term partnerships with clients such as Bentley, MAN and Crown, where performance, durability and trust are essential.

What sets Polgain apart is our ability to combine technical expertise with a commitment to problem solving. We thrive on challenges that others may consider too complex or too specialised. For every project, our aim is simple: deliver precision, reliability and value through engineering excellence.

At Polgain, your project is our priority.
