Core Shaft: High strength alloy steel 40CrNiMoA material, composite forging, tempering heat treatment, 350 ~ 380HB, improve the strength and toughness, ensure the transmission of screw torque requirements.
Involute spline design with high carrying capacity.
Through our hard research, we adopts the imported heat-resistant tool steel and also adopts the cold rolling processing to make the spline. The products have been tried by customers, and fully meets the performance and quality requirements of similar high-products imported from abroad.
Core Shaft’ Material: high strength alloy steel (40CrNiMoA) material, high strength quality adjustment, hardness 300-350HB, compound forging, improve strength and toughness, ensure the transmission of screw torque.
