Sangroove (Jiangsu) Machinery Co., Ltd. is one of the most reliable manufacturers and suppliers of automotive flywheel in China. If you're going to wholesale cheap automotive flywheel made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Product Overview
The Automotive Flywheel is mounted on the engine crankshaft and plays an important role in transmitting rotational power between the engine and transmission system. It stores rotational energy, helps smooth engine speed fluctuations, and provides a mounting interface for the clutch assembly in applicable vehicle designs.
Sangroove manufactures automotive flywheel castings using gray cast iron and other customer-approved materials. With integrated casting and precision machining capabilities, we support the production of flywheels with customized dimensions, mounting interfaces, gear ring configurations, and balancing requirements.
Product specifications can be tailored to the engine design, transmission configuration, and operating conditions.
