Product Catalog 
DID Group is one of the world’s leading brands in the production of high-quality chains, widely recognized for its technological innovations and commitment to delivering durable, high-performance products for vehicles and industrial equipment. With over 80 years of experience in the industry, DID not only supplies chain products for motorcycles, automobiles, and electronics, but also meets the needs of various fields, ranging from international racing events to industrial production lines. In this article, we will explore some of DID’s flagship products and learn about the advanced technology and superior quality that the company brings to consumers worldwide.
Sprockets
DID sprockets have evolved with the development of the automotive industry. As a sprocket used in automobile engines, the optimal meshing design with the chain suppresses noise and vibration, and its excellent wear resistance contributes to a longer engine life.
Tensioners
Combination of the hydraulic mechanism and the no-back mechanism suppresses chain vibration due to torque fluctuations during engine operation, and it automatically follows chain wear and growth, then suppresses noise caused by chain flapping when the engine is in a non-hydraulic state at engine start.
The tensioner body uses aluminum for weight reduction.
Levers/Guides
Levers and Guides are parts that guide the chain in a sliding manner, shape the running trajectory, reduce the free span of the chain, and suppresse vibration.
For strength requirements, it has a body made of glass fiber reinforced plastic, aluminum or steel, and the chain running surface is made of low friction plastic containing fluorine.
Rims/Spokes/Wheels
The DID rim was born from the constant challenge of reducing the weight of the motorcycle machines required in severe motorcycle racing. The successful development and mass production of aluminum-based light alloy rims have created the era of today’s light and strong alloy rims.
We supply various spokes to manufacturers according to the purpose of use, and we also supply wheels assembled with rims, spokes and other parts to manufacturers.
Handle Pipe
Utilizing the aluminum processing technology and surface treatment technology that we have cultivated so far, we are also mass producing and delivering tapered aluminum handle pipes.
The material used is a 7000 series aluminum alloy, and the surface treatment uses alumite treatment, which has been proven in DID rims. We have delivered to the domestic manufacturer such handle pipe having high strength, corrosion resistance and beautiful appearance, just like DID rims.
Competitive Bicycle Chain
As one of our flagship products, it has received high praise both domestically and internationally. Leveraging the technology developed through motorcycle chains, we have developed a lightweight chain with high strength and rigidity.
Chairlift for Stairs, “Rakuchin-Go”, “ESCORT Slim”
“Helping to enrich life”. That is our basic approach to welfare society. In order to develop welfare equipment that is easy to use and friendly to humans, it is important to incorporate women’s sensibilities into the development, then female staff members are promoted. We aim to create welfare equipment that can be applied not only to public spaces but also to general housing. A stairlifts that supports climbing up and down stairs should be like furniture that gently envelop people and harmonizes with the home. ESCORT Slim has achieved a high level of space saving in addition to the superior design that has evolved from a machine to a piece of furniture. Increasingly, it has evolved into a stairlift that harmonizes with Japanese houses.
Wheelchair Stair Lift
This is a “wheelchair stair lift” that does not require a dedicated hoistway and can be installed on existing stairs. The fastest speed in Japan and the smooth ride are realized, mainly meeting the needs of public spaces such as station buildings.
Stair-Assist Handrail,”AssiStep”
AssiStep is a stair-assist handrail that safely supports people who have reduced motor function and are worried about using stairs. By using AssiStep, the remaining functions can be prevented from deteriorating, and self-reliance support utilizing the remaining functions can be performed.
Stair support
Because of the unit assembly method (module type), the rail can be attached according to the various types of stairs , and by moving the handle attached to the rail, you can safely go up and down the stairs. The rails can also be used as handrails.
Easy installation
It is not building equipment, so not necessary to take procedures such as reporting to the administrative agencies to install. The installation is completed in a day, just like a general stair rails.
