A gearbox housing needs its bearing seats, mounting geometry and cast structure defined together. This OEM/ODM enquiry names a sand-cast ductile-iron housing with reinforced ribs and CNC-finished bearing seats for industrial power transmission. Dimensions are customized to the requested component.
Define the bearing-seat and rib arrangement
Provide the housing drawing with the bearing locations, rib geometry and mounting interfaces. Identify the datums and dimensions that control assembly. The supplied 0.01–0.05 mm tolerance reference should be assigned to the relevant dimensions, convention and manufacturing stage.
- Supply 2D PDF/CAD or 3D IGES/STEP data.
- Select the full iron grade and required condition.
- Mark bearing-seat dimensions and finished limits.
- Identify rib and mounting-interface requirements.
- Specify the treatment and acceptance checks.
- State quantity and required inspection records.
Select the complete grade and surface condition
Material enquiries use HT250/300/350 and QT450/500/600-3/700-3 references. Identify the complete designation and standard for the actual housing rather than treating those labels as one material. Sandblasting, painting, powder coating and phosphating are named finish choices to select for the component.
Agree inspection for the finished housing
The service states 100% inspection and wooden-case packing. Define the bearing-seat, mounting and other dimensional checks required for the order. The reinforced-rib description identifies the offered geometry, while any stiffness, load or alignment acceptance should be established by the project. Keep the drawing, selected grade and supplied condition consistent throughout the housing request.
