Detailed introduction to spline hub:

We heat our products by medium frequency to have stable performance and test them by automatic go-no-go test equipment, in order to produce spline shafts with high quality; torsional resistance highly polished; no corrosion; no burr.

Our products have passed the standard attestation of QS9000 quality system, which is for auto industry.

Firstly, the product adopts the high quality alloy steels 40Cr, self-designing and make the mold by us.

Secondly, the product forging, quenching and tempering make it thinning internal organization, eliminate internal osteoporosis and have high tensile strength, yield strength and fatigue strength.

Thirdly, it has good toughness and long service life and very good cutting sex.

Lastly, product machining allowance is small, fast delivery time, for your process to improve work efficiency descending, low consumption costs have laid a good foundation.
