Linear roundrails – classic components for reliable linear motion

Linear round rails are long established as machine elements for the execution of linear motions and have optimally withstood the test of time in industrial applications. They can be used for example as adjusting units in automation tasks.

Linear round rails are robust, reliable, powerful and – due to their simple construction – very economical. The construction of the round rails, which is based on hardened guide carriages in combination with different linear-motion bearings or linear-motion bushes, allows many possibilities for variation. Rodriguez also offers sliding bearing variants.

In addition to the type of bearing, there is also a broad spectrum of guide elements to choose from. Mounting the guide shaft on different shaft supports and the use of open guide elements create additional possibilities for variations. Linear roundtrails with shaft support provide an economical and robust alternative to profiled rail guides.

single Shaft Assembly (SBR or TBR series) is a complete assembly which simplifies the use of a linear bearing in a mechanical positioning application. Each assembly has a steel shaft mounted to a anodized, precision machined, aluminum support.  The pre-drilled base mounting holes supports allow for easy customer mounting.  The SBR or TBR assemblies come in standard lengths or customized length, and with shaft diameters from10mm to 50mm
