Rexnord EARTH-31.63 USNT Inline Gear Reducer

The Rexnord EARTH-31.63 USNT Inline Gear Reducer is a Planetgear Earth-size, concentric inline gear drive designed for high-torque speed reduction in demanding industrial environments. It delivers a 31.63:1 reduction ratio as part of Rexnord’s Earth family, whose standard ratios span 3.53:1 to 1,785:1 and are built for rugged, long-life operation. Earth-size drives provide substantial torque capacity, with catalogs listing torque up to 76,000 in-lb for appropriate configurations. The inline design yields a compact footprint and straightforward shaft alignment, making it well-suited for installations where the driven shaft runs in line with the motor shaft and where reliable, efficient power transmission is required in space-constrained equipment. Planetgear inline drives are rugged by design and site-proven in the world's most demanding applications, with Rexnord offering housing kits and accessory options to tailor mounting, lubrication, and serviceability to specific installations.
