Types of Chain

Tsubaki is the world leader in chain technology, and is continuously improving designs and technologies to adapt to an always changing automotive environment.

Several Chain types are available, depending on the requirements of the application and the demands of the customer.

Available pitches: 7.0mm, 9.525mm (3/8 inch).



Tensioners play a very important role in automotive chain drive systems.

A tensioner, pushing either directly on a chain or on a pivoting guide, takes up slack in the chain circuit, and extends to make up for chain wear and thermal expansion. It also dampens and limits chain movement, which is important to control noise, chain tension, and vibration resonances.

Tensioners can be mechanically and hydraulically tuned to meet customer and component requirements.

Tensioner bodies are made from high strength Steel, Cast Iron, or Cast Aluminum alloys to attain the optimum combination of fit, weight, and economy.
Block Style tensioners are designed to be mounted on the face of engine block.

Flange Style tensioners are designed to be mounted on the engine externally.

Cam-Cam Style tensioners are designed to be mounted at 90° to the Chain plane (such as on top of a cylinder block), and its compact design can fit within the short chain spans between DOHC camshafts.

Sprockets are the rotating elements which both drive and are driven by the Chain.

Sprocket design is tightly controlled by Tsubaki to ensure proper mesh, strength, and durability.

Various materials, fabrication methods, and heat treat options can be selected, depending on Chain type, load, speed, and NVH requirements.

Guides / Levers

  Automotive Application of Guides and Levers
Specialty Services

The role of fixed guides is to provide a low friction, wear resistance platform to guide the chain span between sprockets.
The guide shape is dictated by chain span requirements, interference features, and material wear and strength properties.
The guide Shoe (the chain contact portion) material is wear resistant nylon, while the base material is glass filled plastic, aluminum or steel depending on strength and mounting constraints. Smaller or lightly loaded Guides can also be all plastic if loading conditions allow.
The lever design and function is similar to the Guide, except its design allows it to pivot. A lever is used in conjunction with a tensioner to take up chain span slack and control chain motion.
