Why choose us?

(1) Adopting high power press machine to realize interference fit
We are using a high power press machine which can produce 80T thrust to realize all the combination of spindle head and steel tube for the air shafts. Light type air shaft is with 0.03mm interference fit. Heavy type air shaft is with 0.06mm interference fit. While many factories knock it in with a big hammer, no quality and accuracy.

(2) Adopting hi-precision cold-drawn steel tube as the shaft body
We adopt hi-precision cold-drawn steel tube as the shaft body. The thickness of this kind of tube is uniform so when the rubber balloon inside is inflated, all key strips will stick out at same height. And it will greatly weaken centrifugal force of the whole air shaft when it is rotating and will keep a dynamic balance.
