Featured Products
Camshaft Timing Belt
Our overhead cam (OHC) Timing Belts are designed for synchronous power transmission, maintaining precise camshaft and crankshaft timing in internal combustion engines. These belts deliver dependable performance with minimal elongation, making them ideal for both high-speed and high-torque applications.
Flexible, fabric-free Raw-Edge V-belts are used in the engines of automobiles, trucks, buses, and construction machinery. Ideal in harsh load fluctuation and high-temperature environments, these belts have excellent heat resistance, abrasion resistance, and deformation resistance.
Accessory V-ribbed Belts
Mitsuboshi serpentine RIBSTAR™ and Star Fit® belts provide quiet, efficient performance for accessory drive systems in passenger and commercial vehicles. Their multi-ribbed construction offers superior flexibility and power transmission across multiple pulleys, enhancing belt-to-sheave contact and reducing slippage.
Electric Power Steering Belt
Electric Power Steering (EPS) uses an electric motor to assist the driver's steering, providing more precise control and improved fuel efficiency compared to hydraulic systems. In EPS, timing belts transfer power from the motor to the steering mechanism, ensuring smooth, quiet operation with minimal maintenance.
