Description

HEIDENHAIN SRZ-041 HB-R54VD-01 Rotary Drive Actuator – SRZ Series Precision Encoder-Integrated Actuator

When a rotary drive actuator fails on a CNC machining center, grinding machine, or precision measurement system, the entire production line halts. Positioning accuracy collapses, spindle feedback is lost, and costly unplanned downtime begins. The HEIDENHAIN SRZ-041 HB-R54VD-01 (Part Numbers: 0050-90653 / 0100-09131) is the factory-specified replacement that restores full closed-loop control and gets your equipment back to spec — without compromise.

Within the HEIDENHAIN SRZ Series, the SRZ-041 occupies the mid-range precision tier, engineered for applications demanding high rotational accuracy, compact integration, and long-term reliability. HEIDENHAIN’s SRZ actuators are trusted across European and Asian OEM machine tool builders, and the SRZ-041 variant is widely deployed in high-precision servo and feedback systems globally. Its dual part-number designation (0050-90653 for the assembly unit; 0100-09131 for the configured variant) reflects HEIDENHAIN’s rigorous component traceability standards.
