Sumitomo Heavy Industries PHA9050P2Y-RL-9 Gear Reducer

Sumitomo Paramax 9000 PHA9050P2Y-RL-9 gear reducer is a 200 HP, 1,750 RPM input unit from Sumitomo’s Paramax 9000 series, sized 9050 in the RL-9 configuration. It provides a nominal 9:1 reduction, with a precise ratio of 9.057:1 cited for this model, enabling substantial torque multiplication at reduced speed. In Sumitomo nomenclature, PHA identifies the reducer family and variant, RL denotes the shaft arrangement, and the trailing -9 marks this specific size/ratio variant within the 9050 lineup. As part of the Paramax 9000 family, the unit aligns with Sumitomo’s approach to large industrial gear reductions designed for demanding duty cycles. The 9050 size and RL configuration define its mounting interface and overall footprint within the Paramax catalog, and the RL-9 designation indicates the exact shaft arrangement used for this model. This combination—200 HP input capability, 1,750 RPM input, and a 9.057:1 ratio—supports applications requiring high torque at slower output speeds in heavy industrial drives.
