SEAWIDE: Industrial Gearbox Specialist for Heavy Production Plants

Ultra‑Stable Energy Flow

Engineered for industrial continuity, SEAWIDE’s planetary system guarantees optimum load‑sharing balance across each planet stage.

Result: smoother torque delivery, reduced vibration, and measurable electrical savings in high‑duty workstations.

Military‑Grade Build Integrity

Housing alloys and precision‑cut gears undergo proprietary SEAWIDE heat treatment — extending fatigue resistance under stress from mills, mixers, and agitation systems.

Each housing resists corrosion, thermal shock, and microcracking even in abrasive, contaminated environments.

Adaptive Mounting Interfaces

Dozens of interface geometries (hollow spline, shrink‑disc, double‑keyed, and extended flange) simplify retrofitting and OEM integration without redesigning your motor layout.

Performance Tailoring at Purchase

Unlike catalogue‑only suppliers, SEAWIDE configures gear stages, ratios, and bearing classes per project torque curve.

That means your gearbox leaves the factory matched to its real‑world duty profile — no oversizing, no wasted cost.

Engineered Torque Continuity

Proprietary stage geometry supports continuous torque up to 400 000 N·m, maintaining linear load response with negligible backlash (< 8 arcmin).

Perfect for hoists, separators, kiln drives, and vertical mills.
