EP-SL35003 3-Stage Inline Planetary Gearbox
Brevini Riduttori SL35003 Compatible Replacement | EVER POWER
EVER POWER’s EP-SL35003 is a 3-stage inline planetary gearbox in the Brevini SL/SC compatible replacement range, rated at approximately 35,000 Nm output torque. The SL series inline planetary gearbox is engineered with full dimensional compatibility to the Brevini riduttori SL35003 — the same flange pattern, output shaft and housing register — enabling maintenance teams to replace failed units without machine downtime beyond the installation itself. With IP66 sealing, synthetic oil bath lubrication and a forged carrier assembly, this unit is designed for long service intervals in demanding continuous-duty industrial environments.

Working Principle
The three-stage epicyclic design of EP-SL3503 achieves maximum ratio range by stacking multiple reduction stages coaxially. Input power from the motor enters the first sun gear. The planet gears — mounted on a precision carrier — orbit the sun and react against a fixed ring gear, stepping down speed and multiplying torque at the carrier output. This carrier then drives the next stage input, compounding the reduction. The output shaft or hollow bore is supported by a back-to-back bearing arrangement providing combined axial and radial load capacity for direct sprocket, coupling or gear drive connections.

◆ 18-Month Warranty
EVER POWER’s 18-month warranty exceeds the 12-month standard of most European OEM suppliers. |
Structure and Material Technology
The one-piece GGG50 ductile iron housing is stress-relieved after casting and precision-bored to eliminate misalignment between gear stages. Planet journals run on needle roller bearing assemblies with hardened pins, providing maximum radial stiffness in the compact housing diameter. The output flange register face is precision-turned to 0.015 mm total runout for accurate shaft coupling or sprocket mounting without eccentricity. O-ring face seals at housing joint faces use HNBR compound for compatibility with biodegradable hydraulic fluids.
Typical Application Scenarios
| Industry | Application | Key Benefit |
|---|---|---|
| Automation | Servo-driven conveyor indexing | Low backlash ensures accurate step-and-repeat positioning. |
| Packaging | Robotic palletiser arm joint | High-speed servo input with smooth torque output. |
| Material Handling | AGV wheel drive unit | Compact body integrates into narrow wheel hub envelope. |
| Printing | Web tension control dancer roll | Precise speed regulation for consistent tension across wide web. |
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 — IP66 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.
