| Format | Best For | Compatibility | | :--- | :--- | :--- | | | Universal choice – Preserves geometry and tolerances. | All CAD systems (SolidWorks, Fusion 360, Inventor, NX, Creo, FreeCAD). | | IGES (.igs) | Older systems or data exchange. | Good, but sometimes loses surface definition. | | SolidWorks (.sldprt) | Native use in SW. | Only SolidWorks (and some competitors via import). | | STL (.stl) | 3D printing a visual reference. | Not for engineering analysis – mesh only, no solid geometry. | | Parasolid (.x_t, .x_b) | High-precision CAM/CAE. | Preferred for machining or advanced simulation. |
Next time you specify an oil seal (e.g., 35x52x7 NBR with spring), do not reach for the paper catalog. Go straight to your preferred CAD library, download the validated STEP file, and drop it directly into your assembly. Your future self – and your production line – will thank you.

In modern mechanical design, accuracy is non-negotiable . Whether you are designing a hydraulic system, an automotive gearbox, or a industrial pump, the humble oil seal (also known as a radial shaft seal or rotary seal) plays a critical role in preventing leaks and contamination. But designing around a physical catalog alone is no longer enough. Enter the 3D model . | Format | Best For | Compatibility |
