RUKO KEB-HM-65,0mm freno elettromagnetico a pressione di molla, 100 Nm, 205 V DC, foro 65 mm

Industrial machinery that must stop reliably when power is lost needs a brake that engages without external energy. The RUKO GMBH KEB-HM-65.0mm is a spring-applied, fail-safe electromagnetic brake that holds or stops rotating shafts with a static friction torque of 100 Nm. It operates on 205 V DC and is built for flange mounting on shafts with a 65 mm bore diameter.

Who is it for

This brake suits machine builders, maintenance engineers, and automation specialists who require a power-off braking solution for conveyors, hoists, wind turbines, or packaging equipment. It is intended for applications where a controlled stop or holding function is critical for safety and process integrity.
