Merrit Davis: Retrofitattable gearboxes for extruders

If you have an older extruder that is underpowered by today’s standards, or one with a worn-out gearbox but a usable barrel and screw, upgrade it. Merritt Davis, Hamden, Conn., has introduced the first universally retrofittable, standard gearbox assemblies for 4.5-, 6- and 8-in. extruders of virtually any make. Adapters are available for a range of brands, including Sterling, Davis-Standard, NRM, Battenfeld Gloucester, Welex, and HPM. Merritt Davis offers helical, hardened, and ground double- and triple- reduction gearing.
