EP-SL35002 2-Stage Inline Planetary Gearbox
Brevini Riduttori SL35002 Compatible Replacement | EVER POWER
When a Brevini SL35002 needs replacement, EVER POWER’s EP-SL35002 delivers a dimensionally compatible solution at a fraction of the OEM cost. This 2-stage inline planetary gearbox produces approximately 35,000 Nm output torque from a sealed IP66-rated housing that installs directly into the original machine mounting without modification. Serving cement, mining, chemical, food processing, paper and marine auxiliary drive applications, the EP-SL35002 from EVER POWER offers a cost-effective alternative backed by ISO 9001:2015 quality management and CE certification.

Working Principle
Inside the sealed, oil-bath lubricated housing of the EP-SL3502, two cascading planetary stages convert the high-speed, low-torque motor input into a reduced-speed, high-torque output at the driven shaft. A floating sun gear arrangement between stages automatically centres the load distribution across all planet gear contacts, compensating for minor alignment errors between the motor shaft and the driven machine. This self-centering feature extends planet bearing life in long-service installations where perfect alignment cannot always be guaranteed.
Core Advantages
|
► 35,000 Nm Rated Torque
Full rated output torque for demanding continuous industrial duty cycles. |
● 2-stage Efficiency
Balanced efficiency and ratio range for the required application. |
|
▲ Brevini SL3502 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
Planet gears use 17CrNiMo6 carburised and profile-ground steel, providing superior fatigue life versus 20CrMnTi at equivalent case depth. Carburising is controlled to 0.8-1.1 mm with a core hardness of 30-38 HRC for impact resistance. The ring gear is 42CrMo4 through-hardened and bore-ground after hardening for dimensional stability. The planet carrier is a single-piece forged nodular iron construction, eliminating the flex found in welded split-type carriers. Output shaft seals are double-lip FKM for long life in synthetic oil service.
Typical Application Scenarios
| Industry | Application | Key Benefit |
|---|---|---|
| Cement | Vertical roller mill drive | High-efficiency drive for energy-intensive vertical grinding mill. |
| Mining | Large ore SAG mill auxiliary | High torque sustained over long continuous operating cycles. |
| Marine | Ship thruster auxiliary drive | Reliable low-speed output for large vessel thruster systems. |
| Ports | Gantry crane travel drive | High torque for loaded container gantry crane travel on rail. |
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: 10:1 – 60:1.
- Stage Count — 2-stage provides ratio range 10:1 – 60:1. 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: Is third-party inspection available?
A: Yes. DNV GL, Bureau Veritas, SGS, and TUV inspection can be arranged. Please specify the inspection requirement at order, as it adds approximately 1-2 weeks to the standard lead time.
Q: What is the maximum shock load capacity?
A: Standard units are rated for momentary overload torques of 2.5x the rated output torque. A reinforced variant rated for 3.0x momentary overload is available for high-shock applications such as conveyor head drives with belt sag loading.
