Most industrial buyers know what a worm gearbox does — but few understand how it’s made, and fewer still know how to evaluate the manufacturing quality choices that determine whether a $45 NMRV063 will last 3 years or 10 years in the same application. The...

Every worm gearbox in industrial service worldwide contains the same fundamental pairing: a hardened steel worm screw meshing against a softer bronze worm wheel. The bronze wheel is the deliberately sacrificial component — designed to wear gradually over the service...
