High Rigidity Cast Iron Reducer Housing with Reinforced Rib Structure and Integrated Multi-Bore Design for Heavy Transmission Equipment

Our cast iron reducer housing, also known as gearbox shell, is the key casing component for industrial speed reducers and gear transmission units, normally made of high grade gray cast iron HT200 or HT250, which features high rigidity, good vibration absorption and excellent sealing performance, protecting internal gears, bearings and lubricating oil during continuous heavy-load operation. This gearbox casting adopts reinforced rib structure and integrated multi-bore design, the mounting holes and flange structure are integrally cast to ensure assembly accuracy and stable bearing capacity. We can produce reducer housing according to customer drawings or samples, strictly control wall thickness, hole position and flatness, carry out raw material inspection and defect detection to check sand holes, shrinkage and air porosity. We can supply raw casting blanks or provide stress relief annealing, shot blasting, machining and surface anti-rust treatment. This transmission housing casting is widely used in mining machinery, construction equipment, metallurgical and conveyor transmission systems. We support OEM custom casting and bulk orders, small trial orders are acceptable with stable delivery schedule. As a casting sourcing platform, we cooperate with professional foundries to provide qualified gearbox castings for global transmission manufacturers, engineering machinery factories and industrial equipment purchasers.
