Reliable Seat Scroll Spring Supplier
We have ordered scroll springs for our car seat recliners from Jinrui for over half a year. All springs use 65Mn oil-quenched steel as promised, no deformation after long-term repeated adjustment. The fatigue test reports they provided helped us pass our factory inspection smoothly. Stable delivery and professional technical support, highly recommended for automotive seating manufacturers.

High Durability for Public Transport Seats
Our high-speed rail passenger seats require springs that can withstand millions of use cycles. Jinrui’s coil springs show excellent wear resistance, greatly reducing our after-sales repair rate. Their team can customize torque and dimensions according to our drawings, and the bulk order lead time is always on schedule. Trustworthy long-term partner.
