The Precision Ground Clutch Input Shaft is used at the input side of a clutch-related transmission assembly. Its ground surfaces and gear-related dimensions must meet the specified fit requirements so that the component can be installed in the intended system.

We manufacture this shaft from 20CrMnTi steel and use carburizing and quenching to achieve HRC 58–62. DIN Grade 7 is the specified gear accuracy requirement for designs that include the corresponding gear features.

OEM/ODM Customization

We manufacture according to customer drawings and technical specifications. Please identify the surfaces requiring grinding, critical dimensions, gear features and fit tolerances. Standard production generally takes 30–50 days, while customized production generally takes 45–60 days.

Quality Control

Inspection is based on the approved drawing and agreed technical requirements. The specified hardness and DIN Grade 7 gear accuracy are included where applicable. Ground surfaces and critical fitting dimensions should be clearly identified to avoid ambiguity during production and inspection.
