Both systems can provide an all-in-one solution for controlling rotary and tilting motions to within 2.5 arc-sec and feeding the position back to a CNC system. Heidenhain says that the modules are a realistic alternative to an air bearing solution.
Available with a 35 or 100 mm diameter hollow shaft and an axial load capacity of 200 N, the SRP 5080 and SRP 5010 have frictional torque below 0.2 Nm, supporting motion at up to 3,000 rpm.
