EPNMRV040 Aluminium Worm Gearbox \u2014 Overview<\/h2>\n

The EPNMRV040 aluminium worm gearbox is the workhorse of light-duty outdoor applications, trusted by Australian agricultural equipment manufacturers for its corrosion-resistant housing and robust 2.3 kg build. Rated for input powers up to 0.55 kW with output torque reaching 53 Nm, it handles the varied load demands of irrigation gate operators, seed drill drives, and small conveyor belt systems without overheating. The EPNMRV040 is the smallest EPNMRV model to offer four output flange variants (FA, FB, FC, FD) and accepts NEMA 56C flanges \u2014 features that make it highly versatile for Australian machinery exporters building simultaneously for the North American and Asia-Pacific markets.<\/p>\n
