Welcome to the

Llewellin's Machine
Company Ltd


Llewellin's Gears undertake design, manufacture and reverse engineering projects for many process plants and engineering companies throughout the world.

Llewellin's Gears can quickly supply gears for new industrial equipment or can reverse engineer, repair, rebuild, or replace gears, gearboxes or transmission equipment for existing equipment.

In the event of a breakdown or planned maintenance work our gearbox rebuilding service is prompt and efficient. We can offer an out-of-hours service by arrangement.

Customers often take advantage of our extensive gearing & material expertise, to increase load capacities, vary ratios or even reduce backlash.

Our capabilities, backed up with almost a century of gear and transmission experience as well as our extensive manufacturing facility, will give you the peace of mind that comes from knowing that your gearbox or transmission system is in the hands of true professionals.

Our mission is to meet our customers’ requirements quickly. To help us achieve this aim we hold approximately 100 tonnes of certified raw stock.

If you have a "gear or transmission problem", no matter how large or small, please contact us for a rapid, friendly and competitive response.
