precision gearbox assembly
Precision gearbox assembly for engineers by engineers.

Over 40 years of experience allows us to respond creatively and efficiently to your requirements with our engineering, manufacturing and assembly knowledge.

Practical know-how and proven assembly techniques enable us to build gearboxes, gearheads and other mechanical assemblies to the most exacting requirements. Most of this work is built up from components that we manufacture, whether to customer specification or to our own rigorous set of standard specifications. With our ability to vertically integrate we can offer cost effective solutions for your assembly requirements. We are specialists in precision gear assemblies, bearing assemblies, motor assemblies and electromagnetic sub-assemblies. We can supply fully tested and vetted assemblies.

Cost-Effective and Proven Gearboxes
With increased subassembly outsourcing, the need for responsive qualified gearbox suppliers has grown significantly. Our 40 years of experience allow us to respond creatively and efficiently to these requirements with our engineering, manufacturing and assembly know-how, integrated with performance testing.

Quality Management

Quality Control
For over 40 years, quality has driven Gear Suppliers. Today, we incorporate the latest inspection techniques and a continuous improvement program to ensure the quality standards are maintained at the highest levels. We operate under an ISO9001 certified quality management system. Our stringent quality control environment begins at the operator level so that any inconsistencies can be discovered early in the process.

Experience to Meet Your Requirements
We been building to custom gear requirements for over 40 years and we’re still going strong. Time and time again customers continue to bring us application requirements that no other manufacturer can do quickly and inexpensively. We have designed and assembled hundreds of custom gearheads. Many applications include semiconductor, food packaging, military and medical industries. So whether it’s something simple as a special shaft or ratio or something more complex we encourage you to contact us.

Linear Slide
Our gearheads are easily adapted to any of the commercially available linear slide products on the market. All of our inline or right-angle gearheads can be used to help reduce inertia. Our products match up directly to products manufactured by: Intek, Linear Industries, Daedel, Star Linear, THK, NSK, IKO, Warner, Tol-O-Matic, Macron Dynamics and Industrial Devices.

Custom Shaft Options
Our gearheads offer increased design flexibility when built with custom shaft options such as dual-output shaft, hollow shaft and even custom input shafts that allows easy mounting to options like brakes, encoders or safety couplings that are used between the motor and the gearhead.

Aerospace & Medical
We have custom products for the and custom components for surgical hand tools for the medical industry. Companies have relied on us over the years to build non-standard products that meet the stringent requirements of these this very important industry.

Semiconductor & Food Packaging Equipment
We custom design and manufacture gearheads that can be manufactured with special seals and special grease for both the semiconductor and food packaging equipment industries. These gearheads meet various IP ratings and are usually painted white rather than our standard black anodized.

We design and stock single or double shaft gearboxes and gearheads. All gearbox assembly carried out using only the finest high-technology metal and non-metal components. Custom and standard spur offset gearmotors are also available.
