Miniature Ball Rail® Systems

Miniature Ball Rails feature high load capacity and small dimenstions for smooth transport in precision engineering, testing, and processing applications.


High load capacity in a miniature size

The Miniature version of the Rexroth Ball Rail System has been developed specifically for the precision engineering sector, i.e. for the production of optical or electronic data processing devices, where rolling-element linear motion guideways of extremely compact dimensions and high load capacity are required. The linear motion guideways have equal load capacities in all four directions of load application.
