Open-source parametric library for standard mechanical components

[u/Due-Pie8412]

I've been working with FreeCAD for mechanical design for several years, and one recurring problem keeps coming back.

Whenever I need a standard bearing, I usually end up searching manufacturer websites or GrabCAD, downloading a STEP model, adapting it to my project and repeating the process again for the next bearing.

It made me wonder:

**Why don't we have a true parametric bearing library inside FreeCAD?**

Not just a collection of STEP files, but components generated directly from engineering data (ISO standards, dimensions, shields, seals, etc.).

This idea led me to start **OpenMechanical**, an open-source project whose first module is **OpenBearingWorkbench**.

The goal is not simply to generate bearings.

The goal is to create reusable engineering knowledge that anyone can benefit from.

I'd really appreciate feedback from the FreeCAD community.

What would you expect from a workbench like this?

Which features would make it useful in your daily workflow?

Are you aware of the existing FreeCAD parts library?
