Frequently Asked Questions About Custom Hydraulic Bell Housings & Adapters
What custom hydraulic bell housings & adapters does SIMIS supply?
SIMIS supplies custom metal components such as cast iron pump bell housings, aluminum motor-pump adapters, steel coupling housings. Products follow the customer drawings and the agreed supply condition. SIMIS provides individual metal components and specified subassemblies rather than assuming responsibility for complete equipment.
Can SIMIS make custom hydraulic bell housings & adapters from my drawings?
Yes. The manufacturing scope is based on customer-supplied 2D drawings, available 3D CAD models, specified materials and order quantities. Custom castings, forgings or finished metal components can be considered according to the design and production requirements.
What materials can be used for custom hydraulic bell housings & adapters?
Material options for suitable projects include gray cast iron, ductile cast iron, aluminum casting alloys, cast steel or specialized stainless steel. The actual alloy grade and manufacturing condition are specified by the customer; materials are not automatically interchangeable across different applications.
Which casting and forging processes are available?
Depending on the component and customer requirements, manufacturing options include sand casting, shell mold casting, aluminum pressure die casting. Each manufacturing quotation reflects the particular drawing, required material and production volume. Secondary operations are supplied only to the extent requested by the customer.
How do I request a quotation for custom hydraulic bell housings & adapters?
Please email the component drawing or CAD file, material specification, required quantity and desired supply condition to info@simis-group.com. Where the customer requires machining, heat treatment, finishing, inspection or assembly, those requirements can be included in the drawing or RFQ.
OEM Custom Hydraulic Bell Housings & Adapters Made to Customer Drawings
Hydraulic bell housings are structural motor-to-pump adapters that position a pump relative to the drive motor and provide room for a shaft coupling. SIMIS manufactures custom metal bell housing castings and adapters according to customer-specified mounting interfaces.
SIMIS provides OEM casting and forging manufacturing for metal parts used in customer-specific machinery and equipment. Production can cover the casting or forging blank, a finished metal component or an agreed mechanical part set. The material, drawings, order quantities and delivery condition are established by the purchase specification.
This page introduces the principal parts that may be supplied, the available metal-forming routes and the industries that use them. Rather than offering a universal specification, SIMIS manufactures each project according to the technical requirements provided by the OEM.


Types of Custom Hydraulic Bell Housings & Adapters and Related Metal Parts
Our product range includes individual metal components for different equipment models. The table below describes typical OEM product categories, not fixed off-the-shelf sizes. Customers can submit drawings for other compatible forms and custom dimensions.
| Custom component | Typical OEM product description |
|---|---|
| Cast iron pump bell housings | Robust custom adapter housings for suitable industrial hydraulic power units. |
| Aluminum motor-pump adapters | Lightweight cast housings for customer-specific drive arrangements. |
| Steel coupling housings | Specialized steel metal adapter bodies and supporting structures. |
| Pump mounting flanges | Separate metal interface plates and adapter components. |
| Coupling enclosure components | Bell housing bodies and removable metal cover components to specified designs. |
Component geometry, material grade and manufacturing condition vary between orders. SIMIS supplies customer-specific castings and forgings for both new equipment programs and suitable replacement-part production.
Related SIMIS product manufacturing capabilities include custom pump housings. These may support compatible OEM programs using similar metal components.

Casting, Forging and Metal Manufacturing Processes for Custom Hydraulic Bell Housings & Adapters
SIMIS supplies a range of customer-specified castings, forgings and other compatible metal components for this product category. Each manufacturing method is introduced below to show the kinds of OEM parts that can be supplied. The actual manufacturing process and required supply condition follow the customer’s approved drawings and order requirements.
| Manufacturing process | Typical custom parts and applications |
|---|---|
| Sand casting | Cast-iron and selected steel bell housings and larger adapter structures. |
| Shell mold casting | Repeat-production compatible iron housing components. |
| Aluminum pressure die casting | Suitable aluminum motor-to-pump adapters in repeated orders. |
| Gravity permanent mold casting | Selected aluminum housings for suitable geometries and volumes. |
Sand Casting for Cast Iron Bell Housings
Sand casting is a common route for substantial cast iron motor-to-pump bell housings, adapter structures and related mounting pieces. The process allows a defined external envelope with a hollow central space suitable for the customer’s motor and pump arrangement.
Shell Mold Casting for Repeat-Production Iron Bodies
Shell mold casting can be considered for compatible repeat-production iron or steel bell housings and similar structural components. It differs from conventional sand casting in its tooling and molding approach while still producing a metal casting blank according to the order.
Aluminum Die Casting and Gravity Casting
Selected aluminum hydraulic bell housings and motor-pump adapters may be produced by high-pressure die casting or gravity permanent mold casting. The available process depends on the size, alloy, part configuration and order volume. SIMIS supplies the housing or adapter rather than a complete hydraulic pump coupling system.
Related SIMIS manufacturing services: sand casting, shell mold casting, aluminum die casting. The service quoted for a particular part is determined from the customer’s specified material, drawing and production quantity.


Materials Used for Custom Custom Hydraulic Bell Housings & Adapters
Different metal grades and product forms are used across these components. SIMIS manufactures suitable parts according to the alloy or material grade specified by the customer. The following material descriptions explain common product families and their manufacturing forms, without replacing a customer’s material specification.
Gray and Ductile Cast Iron
Cast iron is frequently specified for hydraulic bell housings and machine adapters. Gray iron and ductile iron should be treated as distinct material choices, with the customer defining the grade and purchase requirements for each project.
Cast Aluminum Housing Alloys
Aluminum casting alloys are used for selected motor-pump adapters where a lighter metal housing is specified. Suitable pressure die-casting grades and gravity-casting grades are not automatically interchangeable.
Cast Steel and Specialized Stainless Steel
Some custom mounting structures may be requested in steel or stainless steel casting grades. Such materials are supplied where technically compatible with the approved component and production method. The necessary mounting and coupling interfaces come from the OEM drawings.
Material grade, manufacturing condition, machining, heat treatment, coating and inspection are included only as specified by the customer. We supply the agreed casting, forging or finished metal component, while the customer determines the requirements of the complete equipment.
