Generate a bearing block assembly
A pillow block: a rectangular housing carrying a sleeve bearing, with the shaft running through it. The housing bolts to a frame and supports the shaft at a fixed height.
What it is used for
- Supporting shafts on machine frames
- Conveyor and roller mounts
- Test rigs and fixtures
- Replacement bearing housings
Dimensions that matter
| Housing size | Outer block dimensions. |
| Shaft diameter | The shaft it supports. |
| Sleeve | The bearing between shaft and housing. |
What you get
A real solid model you can rotate and measure, plus downloadable STEP (machining and CAD), STL and 3MF (3D printing) and DXF (laser and waterjet) files. Optional built-in analysis covers stress (FEA), thermal, buckling, cost and manufacturability.
Before you see it, the built geometry is measured against the dimensions you stated, checked as a valid watertight solid, and — for assemblies — checked for interference. These are geometry and physics checks; they do not confirm the shape matches what you pictured, so review the 3D view or 2D drawing before relying on the part.
Previewing is free. Downloading is £2.99 per part, or unlimited on Pro (£29/month, £290/year).

Common questions
What file formats do I get?
STEP, STL, 3MF and DXF — the formats CNC shops, laser cutters and 3D printers accept.
Can I change the dimensions afterwards?
Yes. Edit the numbers directly, or describe the change in plain English. Every edit is rebuilt and re-checked.
Do I need CAD experience?
No. Describe the part and its sizes in millimetres.
Is it free to try?
Yes — describing a part and viewing the 3D preview costs nothing.
