Precision Line Shafts

Tuesday, December 30, 2008
ZA series line shafts from R+W install as single units and run smoothly without support bearings. Assembled from cut-to-length extruded aluminum tubing with a precision straightness tolerance of 0.2mm/m, lateral stiffness, and low mass allow for high speed operation at a low cost relative to the additional hardware required to assemble a line shaft system. Proprietary software allows for quick and easy calculation of critical speed, moment of inertia and torsional stiffness for any length.
The line shafts are available in a wide variety of sizes, covering torque ratings from 10Nm up to 4,000Nm and for special applications up to 10,000Nm. They can be made with a variety of coupling output hubs in addition to the traditional clamping hub, such as flanges, expanding shafts and tapered conical clamping hubs.
