Component characteristics

Housing materials are high strength gray cast iron and nodular cast iron. Integral medium and small housing results in good durability and shock absorption ability, and improves shaft strength and bearing lifetime. Meanwhile, streamline design of casting housing and internal noise absorbing layout make easy cooling of fan and great reduction of noise.

Aluminum die-cast housing with attractive outlook, light weight and good heart dissipation ability.

Welded housing adopted in small batch production and large housing.

Gears, pinions and bevel gears are made of high grade alloy with carburize-harden technology. Hardness of teeth surface reaches as high as 58–62 HRC, grinding precision reaching class 5–6 and even class 3 if required. With teeth profile and lead modified, the noise is greatly reduced and the load capacity is largely improved. The roots of heavy duty gears are specially processed to further enhance its load capacity.

Bronze alloy and spun casting in worm wheel guarantee its strength and wear resisting property, thus improves its lifetime.

High grade alloy and carburize-harden technology for worm, and the hardness of surface reaches as high as 45–50 HRC. High Grade alloy and temper-harden technology for thread, and nitrogenization technology for tooth surface, the hardness of surface reaches as high as 500–550 HV, design is optimized and efficiency is improved.

Standard accessories such as bearings and oil seals are provided by international famous brands.

Polyurethane paint RAL 5015 as standard.
