Rigid-body ready Industrial digital twin Proprietary but free Sign-up / registration

Bosch Rexroth CAD

Provider：Bosch Rexroth

Bosch Rexroth offers free CAD (STEP/IGES) for linear motion, pneumatics and hydraulics; its sizing tools generate whole-axis 3D models plus calculations — L1, registration required, not redistributable.

Readiness
L1 · Rigid-body ready
Rationale
3D CAD for linear motion, pneumatics and hydraulics generated alongside sizing calculations, with extractable mass properties; no friction, drive parameters or controller models, download requires registration and redistribution is not allowed — hence L1.
Scale
Covers profiled rail systems, ball bush guides and shafts, screw drives, planetary spindles, pneumatic components and hydraulic products; the Linear Motion Designer generates a 3D CAD file for a fully configured axis together with calculations and documentation. (Product scope and LMD capabilities from Bosch Rexroth's official Linear Motion Designer page and the online linear motion selector; the vendor publishes no total model count, so coverage is stated by product family. Checked 2026-10-25.)
License
Proprietary but free — CAD data is free but requires a registered Bosch Rexroth account and is limited to selecting, designing and purchasing Bosch Rexroth products; redistribution as a general parts library is not permitted. The Linear Motion Designer itself is free, and its calculations and saved projects can be used for engineering communication and ordering.

Why it is listed

Bosch Rexroth linear axes and pneumatic components show up constantly in machine building, and the vendor's configurators are one of the few places where the CAD file and the sizing calculation come from the same source of truth.

Readiness assessment

The Linear Motion Designer covers profiled rail systems, ball bush guides and shafts, and spindle drives, and it emits a configurable 3D CAD file for the whole axis after sizing, which is unusual: the geometry matches the dimensioned design rather than being picked from a static catalog. Mass properties are extractable, giving L1. Friction, drive parameters and controller behaviour remain outside the asset.

Practical notes

The LMD is free and runs offline; saved projects allow parameter changes without restarting, which suits iterative design. The browser-based linear motion selector replicates LMD functionality with a 3D viewer, CAD download and online ordering. CAD downloads in general require a registered account.

Pneumatic and hydraulic catalogs expose configurators and per-part-number CAD downloads in several formats; for cylinders with non-standard stroke you can configure the stroke first and then request the CAD model. Use the generated calculation output as the design record and do not treat the geometry as redistributable.
