Gear Coupling

(1) Crowned tooth allowed larger tolerance in shafts and higher loads.
(2) Special hardening treatment W/high strength and anti-abrasiveness.
(3) Closed type coupling--easy lubricate & anti dust as well as no leakage.
(4) The type of TIEN YI GEAR SHAFTS COUPLINGS had been successful the first processing, it must be done the second procedure heat treating again according to material. And it were given them more rigidly precise, increasing stronger tenacity. At last removing gravitation by striking-ball bearing when those steps all finished.
