SEW-EURODRIVE GmbH & Co. KG R27AM143 Gear Reducer

The SEW‑EURODRIVE R27AM143 Gear Reducer is a parallel‑shaft helical gear unit in SEW's R‑series, delivering a 48.17:1 reduction ratio to convert high‑speed input into high‑torque output for demanding industrial drives, with a compact footprint suited to space‑constrained installations. The R27 family uses a high‑strength cast aluminum housing that provides rigidity and a lightweight, compact footprint, aligning with SEW's modular drive philosophy and enabling integration with compatible components to form a complete drive system. Key shared features include an interlocking two‑piece seal design for contaminant protection, a removable inspection cover for service access, and support for metric or inch output shaft configurations to match a wide range of couplings and interfaces. Inverter‑duty operation is supported across the R‑series, with typical efficiencies of 98.5% (1‑stage), 97% (2‑stage), and 95.5% (3‑stage), making the R27AM143 a durable, long‑life option for conveyors, packaging lines, and general automation that require reliable torque multiplication and smooth speed control.
