Import Clutch Diaphragm Spring — Buy in Bulk from Supplier in China

The clutch diaphragm spring from Hebei Fengdong Auto Parts Co., Ltd. is a precision-engineered component for automotive clutch systems, built to ensure consistent engagement and disengagement under load. This spring features an inner diameter of 113mm and an outer diameter of 395mm, dimensions that align with standard clutch assemblies in commercial and passenger vehicles. Constructed from 51CrV4 alloy steel, it delivers high fatigue resistance and structural integrity, critical for maintaining clutch performance under repeated stress cycles.

The material 51CrV4 is a chromium-vanadium spring steel known for its strength and toughness, typically heat-treated to achieve a tensile strength range of 1200 to 1400 MPa. The silver-gray finish provides corrosion protection while maintaining surface smoothness to reduce friction within the clutch mechanism. Diaphragm springs of this type are standard in single-plate clutch systems, where their conical shape converts axial force into radial pressure on the pressure plate.

Automotive manufacturers and repair workshops use this spring in vehicles requiring reliable clutch operation, from light trucks to passenger cars. The component is supplied in bulk with a minimum order quantity of 2000 pieces, packaged to prevent deformation or surface damage during transit. Buyers can confirm compatibility with their clutch models by verifying the diameter specifications and material grade, as mismatches in either can lead to premature wear or system failure.

Hebei Fengdong Auto Parts Co., Ltd. is based in Xingbieying Develop District, Cangzhou, Hebei Province, China, specialising in the production of automotive clutch components. The company’s profile indicates it operates as an imported-tier supplier, with a focus on delivering parts that meet OEM and aftermarket standards for durability and performance.
