Low Friction Loss Belt

Low Friction Loss belt reduces friction loss by minimizing the internal heat generation of the belt rib rubber caused by bending and reduces accessory drive energy loss (engine torque loss). Used mainly by automobiles, recently the trends in the automotive industry include low fuel consumption and fuel efficiency items.

  • Reducing friction loss by minimizing the internal heat generation of the belt rib rubber
Low Modulus Belt

Timing Belt in Oil

In recent years the automotive and general purpose machinery engines have been using metal chain for cam drives. The Timing Belt in Oil was developed to replace the metal chain. We continue to expand to various automotive engines that contribute to light weight and low noise engines and improved fuel consumption. The Timing Belt in Oil, compared to conventional rubber belts, has higher oil and heat resistance and are used inside the engine block (oil environment) where the oil sticks, and up until now rubber belts could not be used.

Benefits of using Timing Belt in Oil
  • While a guide is necessary for a chain drive, it is unnecessary for Timing Belt in Oil. A guide is no longer needed for oil timing drive system, which makes a light weight and low noise engine.
  • Because it has excellent transmission efficiency compared to metal chains, it contributes significantly to improved fuel efficiency and decreases energy loss.
  • Because it can be used in the same way as a metal chain inside the engine block, without greatly changing the engine layout, it is possible to replace with the belt from the chain.
 
 

  
Star Fit

Star Fit® is a V-ribbed belt that interacts with a specific pulley which has no adjustment space.

Star Fit® is a belt used in accessory drives which uses low modulus elasticity cord. It is unnecessary to install a tension pulley and bracket, which allows for reduction in engine space and to lower costs.

The pulley and bracket weight is about 1.5kg in light weight vehicles, which contributes to improved fuel consumption.

Benefits of Using Low Modulus Belt
  • By using the special tool, it can be attached between the fixed axis layout while stretching the belt. This lowers costs and reduces space which is achieved by getting rid of the tension pulley and bracket.
  • Can expect improve fuel efficiency due to the weight of the system.

Giga Torque GX

Giga Torque GX uses a high hardness and flexible carbon fiber cord, in pursuit of strength and flexibility.

We are able to make the belt width compact and the results from saving space, light weight and low noise, is expected to improve the performance of machinery and equipment. Furthermore, this is not limited to timing belt applications, but the scope can also be expanded to chain drive applications.

Benefits of Using Giga Torque GX
High Transmission Capacity

With its high transmission capacity, it will be able to narrow the width in the same conditions as a conventional belt. As a result, it is possible to use a light weight pulley, thereby reducing noise and saving space.

Long Life

Suppressing the elongation of the belt by the carbon cord and improve wear resistance by special processing fabric, it has 1.7-2.2 times more durability compared to conventional high torque timing belt.

High Tensile Strength

By using the carbon cord, the initial tension can be set lower due to less tension decay. Also from suppressing the elongation of the belt, it’s possible to prevent pitch gap and greatly improves durability.

SUPER AG-X
By using newly developed cover fabric and V core rubber, the SUPER AG-X has rapidly improved wear and crack resistance and has a long life.

By using the newly developed cover fabric, wear and slip during times of heavy duty loads reduces the wear caused by friction of the pulley.

By using reinforced short fiber rubber, it can drastically reduce the shock from bending, suppressing the load on the cord.

Performance Comparison of SUPER AG-X
  • Wear Resistance

    SUPER AG-X has 1.3 times the wear resistance of the competitors’ product.
