EPNRV063 Shaft-Input Aluminium Worm Reducer \u2014 Overview<\/h2>\n

The EPNRV063 is the heavy-duty mid-range model in the EPNRV aluminium worm reducer series, combining 160 Nm of output torque with the shaft-input versatility that makes it the first choice for chemical process engineers driving agitators and mixers from existing line-shaft systems. The absence of a motor flange allows the EPNRV063 to be driven by servo motors with non-standard frame dimensions, hydraulic motors, and variable-frequency drives via flexible coupling \u2014 solving the integration challenge engineers face when specifying new speed reduction in brownfield chemical plants and paper mills where standard IEC motor mountings are not always feasible. With 700 N input shaft radial capacity and five output flange options, the EPNRV063 is the most versatile shaft-input reducer in the EPNRV range.<\/p>\n
