Shaft Rail Assemblies

LinearRace® Shaft Rail Assemblies

Thomson shaft rail assemblies and low shaft rail assemblies offer easy installation of your linear race. We mount the solid steel shaft or lightweight tubular shaft to the support rails which are ready for instant bolt-down installation. Shaft rail assemblies eliminate many problems encountered in designing and manufacturing custom shaft supporting devices. Unlimited travel lengths and mounting hole flexibility is another reason why Thomson rail assemblies are right for any application.
