EPNMRV130 Aluminium Worm Gearbox \u2014 Overview<\/h2>\n

The EPNMRV130 is the largest and most powerful unit in the EPNMRV aluminium worm gearbox series, delivering up to 1,596 Nm of output torque from a 7.5 kW input \u2014 making it indispensable in cement mixing plants, quarrying equipment, and large-scale bulk material handling systems. Weighing 48 kg, it is substantially lighter than the cast-iron competitors it replaces, yet its heavy-section die-cast aluminium housing and high-tensile phosphor-bronze worm gear wheel withstand the shock loading and continuous-duty cycles of the harshest mineral processing environments. Australian quarrying and resources companies value the EPNMRV130 for its sealed multi-lip output shaft seals that prevent fine dust ingestion and eliminate oil-loss service calls between scheduled shutdowns.<\/p>\n
