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.

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.
