Hydraulic Motors

HMC Series

The Kawasaki HMC Series Motors have 7 frame sizes ranging from HMC030 through to the HMC325 and have a choice of displacements for the high and low range. Output torques are available from 2.8 Nm/Bar to 172 Nm/Bar Staffa motors are renowned for the excellent reliability. If properly maintained, not subjected to loads or stresses beyond their capability, and used with clean hydraulic oil, Staffa motors have been known to last over 25 years in service. Antech are a trusted supplier for Kawasaki so we can help if you want a Staffa HMC Series Motor to suit your requirements.
