Inline Speed Reducers
Moduline Type R Concentric in-line shaft speed reducers are available with torque ratings up to 233,000 inch-pounds and standard gear ratios up to 985:1. The Type R design reflects the flexibility of the modular concept to provide a readily available drive closely tailored to popular horsepower selections. All units incorporate precision helical gearing in single, double, triple, and quadruple reductions, rugged cast iron housings, and tapered roller bearings. Ratio changes and servicing is made easy with a removable high-speed end.
Moduline Type R Speed Reducers can be arranged for floor, wall, or vertical mounting. Accessories and modifications include bedplates, outboard bearings, backstops, cooling fans for added thermal capacity, motor mounts, C-Flange adaptors, flexible couplings, taconite seals, OSHA approved coupling guards, special marine duty features, custom output shaft dimensions, taconite seals, and special ratios.

Moduline Type G Integral Gearmotors are available in ratings from 1 to 200 HP and output speeds from 1.5 to 1430 RPM with AGMA Class I, II, or III service factors. The Type G design incorporates a standardized AGMA motor flange which aligns a NEMA frame footless AC motor to a modular gear-drive which provides a single source motor and gear assembly. Nuttall Gear can offer either standard or high efficiency AC motors with Nuttall Gear’s proprietary non-NEMA AC motor shaft in all types of motor enclosures. The modular gear assembly incorporates precision helical gearing in single, double, triple, and quadruple reductions, rugged cast iron housings, and tapered roller bearings.
Moduline Type G integral gearmotor can be arranged for floor, wall, or vertical mounting. Many modifications, in both mechanical and electrical, such as brakes, special motor insulation, special oil seals, and marine duty are all available.
All-motor
Moduline Type U Scoop Mount Gearmotors are available in ratings from 1 to 200 HP and output speeds from 1.5 to 420 RPM with AGMA Class I, II, or III service factors. Type U design features a dedicated scoop type mount for standard NEMA frame motors. This arrangement is particularly advantageous where a facility has a standardized motor type or where existing motors must be utilized. Nuttall Gear can offer either standard or high efficiency AC motors in all types of motor enclosures. All units incorporate a concentric in-line shaft speed reducer with precision helical gearing in single, double, triple, and quadruple reductions, rugged cast iron housings, and tapered roller bearings.
Moduline Type U Scoop Mount Gearmotors can be arranged for floor, wall, or vertical mounting. Many modifications such as backstops, brakes, motor insulation, slide rails, special shafts, seals, wet end paper mill features, and a variety of mounting positions are available.
C-Face
Type "Veri-Dri" Vertical Concentric in-line shaft speed reducers are available with torque ratings up to 233,000 inch-pounds and output speeds from 1.5 to 780 RPM. The "Veri-Dri" design is similar to the Moduline Type R but incorporates a "dry-well" construction at the output shaft end. This "dry well" helps to prevent possible oil contamination in the product or process and well suited for water treatment, food processing, and chemical duty on aerators, mixers, agitators, and blenders.
All models can be supplied with an integral gearmotor or a NEMA C-Flange motor adaptor. Additional standard features include a bi-directional shaft mounted lube oil pump and oil flow indicators.
