Product Description:
The BTA20.3-BA-NN-BA-NN belongs to Bosch Rexroth Indramat’s BTA20 series of machine control boards and is built with a bore size of 20 mm and matching shaft diameter of 20 mm. The outer body is formed from steel and supports a structure that stays rigid under load without flex or drift. The open housing type keeps the unit lightweight and simple to inspect when needed.
This unit supports a permissible load of 1,500 N, allowing it to handle higher stress conditions in setups where linear control has to stay tight and controlled. It operates in a broad temperature window from -20°C to 80°C, meaning the material tolerances stay stable even when installed in non-climate-controlled spaces. The ball bushing bearing mechanism used inside helps the motion system glide smoother, reducing the wear rate and extending the time before servicing becomes necessary. The motor’s mechanical design minimizes backlash and enhances responsiveness, which is essential for precise positioning applications.
The overall length is 80 mm with an outer diameter of 32 mm, giving it a balanced profile that’s easy to mount in standard automation frames using its flange mounting setup. Guide accuracy is rated high across factory units, and with 4 ball circuits inside, the motion stays consistent without wobble or sudden friction points. The unit is built without sealing, which might limit its use in exposed environments, but in clean or controlled systems, it makes maintenance quicker and reduces part complexity. The BTA20.3-BA-NN-BA-NN fits best where precision and durability need to work together—motion setups, control rigs, or axis systems that operate on fixed, repeatable paths without needing frequent adjustment or recalibration.
