Introduction
The Shuangxin gear reducer utilizes tenacity iron housing, forged and high-tensile cast steel gearing, being greatly superior to the conventional cast and steel combination. 
All Shuangxin gear reducer features precisely machined herringbone gears. The steel gear after heat treatment exceeds API criteria (mainly the pitting and bending stress). Our design allows extra wide gear tooth interfaces for uniform loading and equalized stress during peak torque operation.
A rugged, fully machined ductile iron case houses component gears, with a split centerline for easy disassembly while alloy steel shafts rotate in oversized precision roller bearings ensure that there is no bronze bushing to seize and no shaft wear from rotational contact.
In addition, there is no oil pump to fail or maintain. Add to that a generous center relief that ensures positive flow to all gear tooth interfaces and a submerged gear and wiper system which delivers a supply of lubricant to the oil galleries and you have a hardworking gear box of the highest possibly quality and craftsmanship.
