Heidenhain introduces all-in-one SRP series modules

Product Launches

Companies building CNC machines incorporating rotary axes would normally need to source and assemble a torque motor, a precision bearing and a high resolution angle encoder. All three items may now be purchased from Heidenhain as a single unit, following the company’s introduction of two new modules, designated SRP 5080 and SRP 5010, which are fitted with an incremental and an absolute encoder respectively.

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.
