Inline Gear Reducers

Direct-coupled inline gear reducers built for high torque at low output speeds in heavy and rugged industrial duty.

Sumitomo Paramax 9000 inline helical gear reducer

Overview

Direct-coupled inline gear reducers built for high torque at low output speeds in heavy and rugged industrial duty. Inline gear reducers couple the input and output shafts on the same axis through one or more helical gear stages, delivering high torque at low output speeds. They are the standard answer for rugged, continuous-duty applications: compressor and blower drives, mining and aggregate equipment, oil and gas process trains, robotics cells, and automation lines, wherever torque density, efficiency, and service life beat compactness as the deciding factor.

Frequently Asked Questions

When does an inline reducer beat a right-angle worm or shaft-mount design?
Inline geometry is the right choice when torque density and efficiency matter more than envelope, and when output torque has to climb without sacrificing service life. We help size the right configuration for the duty cycle.
Can you cross-reference between major inline reducer brands?
Yes. We cross between Sumitomo, SEW-Eurodrive, Nord, Falk, and others, confirming gear ratio, output torque, mounting, and shaft dimensions before quoting a replacement.
