The enduring performance of an outstanding heavy-duty clutch originates from the meticulous selection of raw materials. CNCJPARTS supplies the global market with over 2,000 clutch product models. To ensure our clutches perfectly fit mainstream international commercial vehicles like Mercedes-Benz, Volvo, Scania, and MAN, we are incredibly strict regarding core material applications.

• High-Strength Cover Body: We primarily utilize HT250 high-strength gray cast iron, ensuring the clutch cover maintains excellent structural stability and anti-heat fade capabilities even under extreme high-temperature friction.
• Core Transmission Components: Key transmission parts are forged from 40Cr alloy steel, significantly enhancing torque transmission reliability under heavy loads.
• Diaphragm & High-Load Springs: Our diaphragm springs use 51CrV spring steel , while our high-load spring systems employ 55CrSi spring steel. These materials provide longer-lasting elasticity retention and superior anti-fatigue lifespan.

Thanks to the perfect combination of premium materials and core manufacturing processes, our clutch kits are widely applicable to heavy trucks, buses, construction machinery, and mining equipment. Whether operating in the tropical climates of the Middle East or the freezing environments of Russia and the CIS, CNCJPARTS clutches deliver the most solid driving force.
