Working Principle
EP-SL3504 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 four-stage planetary architecture achieves approximately 35,000 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
|
◼ 35,000 Nm Rated Torque
Full rated output torque for demanding continuous industrial duty cycles. |
★ 4-stage Efficiency
Balanced efficiency and ratio range for the required application. |
|
► Brevini SL3504 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 |
|---|---|---|
| Food Processing | Filling and dosing conveyor | IP65 sealing withstands food-grade wash-down on external surfaces. |
| Pharmaceutical | Tablet press feed conveyor | Smooth vibration-free torque delivery for consistent tablet weight. |
| Textile | Warp beam let-off drive | Precise slow-speed torque control for consistent fabric tension. |
| Assembly | Rotary index table | Low backlash enables accurate workpiece positioning between stations. |
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: 50:1 – 500:1.
- Stage Count — 4-stage provides ratio range 50:1 – 500:1. 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.

Frequently Asked Questions
Q: What is the minimum oil change interval?
A: With synthetic ISO VG 220 oil: first change at 500 hours, then every 2,500 hours or 12 months, whichever comes first. Lifetime lubrication is available as an option for sealed-for-life configurations in applications with limited maintenance access.
Q: What ambient temperature range is supported?
A: Standard range is -25 degC to +80 degC. A low-temperature variant with Arctic-grade PAO oil and cold-rated FKM seals is available for service below -25 degC. A high-temperature variant for up to +100 degC ambient is available on request.
