Check the Pump-Motor Fit Before You Order a Bellhousing
MEISON's full-circle aluminum housing is built around the motor frame, hydraulic pump port, mounting pattern and installation direction. Use this custom bellhousing adapters planning page to separate hydraulic pump-motor data from automotive search intent, then review the bellhousing dimensions before sending drawings.
Core product fit
Start With the Interface, Not the Part Name Alone
The full-circle housing is a mechanical bridge between an IEC motor and a hydraulic oil pump. The useful purchase conversation starts with mounting data.

Fit data strip
Five Inputs Shape the Drawing Conversation
A model number is only useful when the motor and pump data behind it are clear.
Prepare the oil pump port and pump-side data so the interface can be checked against the table.
Compare the oil pump installation center distance with the required mounting pattern.
Confirm hole count, thread, angle and pattern, such as the PK350 4xM12/90° example.
Use drawings or replacement references to settle the final interface before order release.
Meaning and boundary
Keep the Industrial Bellhousing Context Clear
The same word can appear in very different markets. This page treats bellhousing as a hydraulic pump-to-motor connection part.
- Hydraulic equipment context
Use motor frame, pump flange and installation direction as the selection language.
- Automotive wording boundary
Do not treat this as a transmission housing or vehicle drivetrain replacement.
- Confirmation path
Match the selected model with drawings, pump details and MEISON technical support before final ordering.

Fit questions
Full-Circle Bell Housing FAQ
What is this full-circle bell housing used for?
It is used as a pump-to-motor connection part for IEC standard motors and hydraulic oil pumps. The full-circle form supports a rigid mounting bridge for hydraulic power units and heavy-duty pump-motor assemblies.
Which details should be checked before choosing a model?
Check the motor frame, oil pump port, installation center distance, pump mounting holes, bell housing height and whether the motor installation is vertical or horizontal.
Can the bell housing be used for both vertical and horizontal motors?
MEISON lists vertical and horizontal motor configurations. The order description uses L and W to distinguish the motor-end installation method.
How is an industrial bellhousing different from an automotive bellhousing?
In this context, bellhousing means a hydraulic pump-to-motor connection part, not an automotive transmission housing. The fit depends on motor and pump mounting data rather than vehicle drivetrain compatibility.
Why is drawing confirmation important?
MEISON expects oil pump models and parameters from the customer, with supplier drawing confirmation as the primary step. That keeps mounting holes, port data and installation direction aligned before production or ordering.
What should be sent with a first fit inquiry?
Send the motor model or frame size, hydraulic pump model, flange pattern, oil pump port, mounting-hole layout, installation direction, quantity and any available drawing or replacement reference.
