Davall is one of the UK’s most established manufacturers of precision geared components. We have been supplying high quality gears, gearboxes and geared systems since 1885, providing clients within the aerospace, medical, defence and industrial sectors with the power transmission products they need to move forward. 

The Davall Group is made up of three distinct businesses:

  • Davall Gears – Our manufacturing division, responsible for the design, development and distribution of precision gears, gearboxes and geared systems. 
  • Davall Stock Gears – Provides stock and standard catalogue power transmission products.
  • Mollart Universal Joints – Supplies precision-engineered, aerospace standard driveshafts, universal joints and couplings. 

At Davall, we’re driven by quality. The industries we serve demand it, so we stop at nothing to ensure they get it. Product quality has always been, and will continue to be, the foundation upon which our company is built. With a Davall gear you can be absolutely confident in its performance, reliability and longevity, no matter how challenging the application.  

Below you’ll find more information about our products and services. If you require any help or advice, or would like to discuss your transmission requirements with an industry expert, just give us a call on 01707 28 31 00. 

Davall Gears Overview

Davall Gears Ltd specialises in the design and manufacture of gearboxes and gearing systems. Our products are used right across the aerospace, defence, medical, industrial and automotive sectors, for both development and production purposes. Our accreditations include:

  • BS EN ISO9001:2000
  • AS9100: Rev. C

These ensure our products meet the quality standards demanded by industry. 

Using a series of state-of-the-art CNC machine tools, EDM equipment, profile grinders, worm thread grinders and gear cutting machines, we’re able to deliver a complete range precision engineered components and assemblies. 

Davall Spiradrive

Spiradrive® is the name given to our spiroid gearing products, which consist of a gear and pinion that give a much greater torque capacity for a given package space than other, competing right-angled/offset gear systems. Higher torque is achieved by having a large contact ratio (i.e, number of teeth sharing the torque loading). Spiradrive® systems also give exceptionally low, and in fact virtually zero gearbox backlash (subject to manufacturing and build processes). To find out more, head over to our website or get in touch with a Davall expert on 01707 28 31 00.

Design & Engineering

Drawing upon a wealth of industry experience, our design and development team are able to offer both clean sheet solutions and complete gearset or transmission re-engineering services to meet new application/performance targets. 

Whatever your design requirements, we’ll deliver a practical, cost-effective solution. The service includes design, analysis, prototyping and product testing, all of which are carried out within a single site facility. Once all tests have been completed and the final product approved, we can then begin the manufacturing process. 

If you need a new gear component developing or an existing one re-engineering, speak to the team at Davall on 01707 28 31 00.


Davall has been manufacturing precision engineered gear components for over 120 years, making us one of the most experienced suppliers in the market. At our production facility in Hatfield we have a collection of traditional and modern machines and equipment, which together give us the ability to manufacture technically challenging components within very short lead times. Whatever your production requirements, the manufacturing team at Davall can handle them.
