About Us
APG Developments Ltd is a specialist manufacturer of pulleys, gears and transmission components, serving customers across the UK from our base in Rochester, Kent. With many years of hands-on engineering experience, we have built a strong reputation for producing high-quality, reliable and precisely machined parts that support a wide range of industrial applications. Our focus is simple: deliver the right component, to the right standard, at the right time.
APG are a ISO 9001-certified UK manufacturer specialising in:
• Timing pulleys (HTD, AT, T-profile, custom)
• Spur, helical, bevel, worm & internal gears
• Precision-machined components
• Prototype to production batches (1–1,000+)
• Aluminium, stainless, mild steel, brass, acetal + hardened steels via subcontractors
We manufacture an extensive range of pulleys including timing pulleys, vee and poly-vee pulleys, round section pulleys and bespoke pulley systems made to customer drawings. Alongside this, we offer a complete range of gears, sprockets and toothed components in both metric and imperial formats.
Whether you require a standard replacement part or a fully customised solution, our team has the capability to produce components that match your exact requirements.
APG Developments also provides a number of value-added services to give customers a complete end-to-end solution. These include anodising of aluminium parts, chemical blacking of steel components, fibre-optic laser engraving, and the manufacture of toothed bar stock. By offering these services in-house or through trusted partners, we reduce the number of steps our customers need to take and help streamline their procurement and production processes.
Quality is central to everything we do. Every component is produced with close attention to accuracy, material integrity and finish. Our team works to strict quality control procedures, ensuring consistency across small batches, large runs and bespoke one-off orders.
What truly sets APG apart is our customer-focused approach. We work closely with clients to understand their application, design constraints and delivery requirements. This allows us to recommend the best approach, speed up turnaround times and provide a dependable service.
If you are looking for a pulley and gear manufacturer that delivers precision, reliability and flexibility, APG Developments Ltd is ready to support your next project.
