EP-SC6003 3-Stage Inline Planetary Gearbox
Brevini Riduttori SC6003 Compatible Replacement | EVER POWER
The EP-SC6003 from EVER POWER is a 3-stage inline planetary gearbox delivering approximately 6,000 Nm output torque — engineered to serve as a cost-competitive, dimensionally compatible replacement for the Brevini riduttori SC6003. Industrial sectors served: construction materials, mining and quarrying, food and beverage, pulp and paper, chemicals, water treatment and marine auxiliary. Key differentiators: IP65 sealed housing, oil-bath lubrication supporting any mounting orientation, and 18-month warranty from EVER POWER’s ISO 9001:2015 certified facility.

Working Principle
EP-SC603 uses a coaxial drive arrangement where motor input shaft and output shaft share the same centreline, providing maximum torque transmission efficiency with minimum installation footprint. The three-stage planetary architecture achieves approximately 6,000 Nm output torque from a compact sealed housing. Oil-bath lubrication maintains a continuous lubricant film on all gear contacts regardless of mounting orientation — horizontal, vertical or inverted — making this unit suitable for the full range of industrial machine configurations encountered in conveyor, mixer, agitator and rotating equipment drives.
Core Advantages
|
◼ 6,000 Nm Rated Torque
Full rated output torque for demanding continuous industrial duty cycles. |
★ 3-stage Efficiency
Balanced efficiency and ratio range for the required application. |
|
► Brevini SC603 Direct Fit
Identical mounting dimensions — installs in original machine pocket without modification. |
● Oil-Bath Lubrication
Sealed oil-bath serves all mounting orientations — horizontal, vertical and inverted. |
|
▲ 18-Month Warranty
EVER POWER’s 18-month warranty exceeds the 12-month standard of most European OEM suppliers. |
Structure and Material Technology
All gear stages use 17CrNiMo6 case-hardening steel manufactured to vacuum-degassing standards for superior core impact toughness. The output shaft is 42CrMo4 through-hardened, providing high bending stiffness for cantilevered coupling loads. A thermal monitoring boss (G1/4 threaded) is standard on all units with torque rating above 12,000 Nm, allowing a PT100 temperature probe to be fitted for plant DCS integration. External surfaces receive a marine-grade C4 epoxy coating system for outdoor and marine auxiliary applications.
Typical Application Scenarios
| Industry | Application | Key Benefit |
|---|---|---|
| Marine | Deck crane auxiliary winch | IP66 sealing withstands salt spray and high-pressure wash on open deck. |
| Offshore | Subsea cable tensioner drive | High torque combined with slow output speed for cable laying operations. |
| Wind Energy | Pitch and yaw actuator drive | Reliable output torque for blade pitch and nacelle yaw control. |
| Construction | Tower crane auxiliary travel | High reduction ratio allows slow crane travel from standard motor. |
Selection Guide
- Required Output Torque (Nm) — Confirm peak and continuous torque with safety factor of 1.3-2.0.
- Gear Ratio — Motor speed (rpm) / required output speed (rpm). Range: 20:1 – 200:1.
- Stage Count — 3-stage provides ratio range 20:1 – 200:1. Higher stages = higher ratio and lower efficiency.
- Motor Interface — Flange type (SAE / IEC metric), shaft diameter and keyway.
- IP Rating — IP65 is standard. IP67/IP68 upgrade available for washdown or outdoor service.
- Mounting Orientation — Horizontal, vertical or inverted; all supported with standard oil-bath lubrication.
- Operating Temperature — Standard -25 to +80 degC; Arctic and high-temp variants available.
