1.Made of Aluminum alloy die-casting box, nice loking in appearance, compact in constitution rust proofing on Surface and small volume to save mounting space. 2. Good radiating attribute leads safe and excessive performance for using. 3. The stable skill of loading and overload make certain steady transmission, make less vibration and noise. 4. Varies of connecting structure for energy enter and torque output meet different requirements; the design of box outline and the set of foot hole is apt to with excessive many kinds of mounting. 16.Besides massive cases, no gap constitution of box capacity a maintenance-free that's hermetically sealed. It prevents the lubricant from easily losing and going bad, and exchanging, https://ae01.alicdn.com/kf/A2e263c7cca28493fa2f33b9208353c36x.jpg
