Transmission Housing
Product Description
A heavy-duty gearbox demands a highly rigid casing, and we engineer each Transmission Housing to absorb massive torsional forces while maintaining perfect shaft alignment. Employing a combination of sand casting and coated sand molding, we achieve high dimensional precision and clean internal cavities, free of loose sand or casting defects. Our 11 years of structural casting expertise allows us to provide global distributors with gearboxes and housings that eliminate oil leakage risks and reduce operational noise in industrial and automotive drivetrains.
We recognize that the durability of a Transmission Housing depends on its structural integrity under cyclic loading. Therefore, we utilize our advanced CNC machining centers to process critical bearing bores and mating surfaces to extremely tight tolerances. This precise combination of robust casting and expert machining ensures that when you integrate our Transmission Housing into your assembly line, you are installing a component that ensures smooth gear meshing and a highly reliable power transmission lifecycle.
We support comprehensive OEM and ODM solutions to manufacture gearbox housings according to your customized specifications. Our R&D and foundry teams deliver custom prototypes in 30 days, supported by a professional payment structure of 50% prepay and 50% balance. We maintain a standard manufacturing run MOQ of 50 tons, offering B2B buyers a reliable commercial framework of 50% down-payment and 50% final payment.
We provide continuous support by logging a dedicated service archive within 24 hours of your order, ensuring absolute technical traceability. We offer on-site technical guidance and free training programs for bulk buyers to facilitate smooth gearbox assembly. Inquiries are resolved within 12 hours, and standard troubleshooting schemes are issued within 48 hours. Our cast transmission frames carry a 6-month warranty, and precision-finished components are protected by a 12-month warranty.
