EP-SL18001 Single-Stage Inline Planetary Gearbox
Brevini Riduttori SL18001 Compatible Replacement | EVER POWER
The EP-SL18001 is EVER POWER’s independently engineered single-stage inline planetary gearbox, designed as a direct replacement for the Brevini riduttori SL18001. Delivering approximately 18,000 Nm output torque with IP66 sealing and a mounting interface dimensionally compatible with the original Brevini unit, this gearbox serves industrial machinery, conveyor systems, mixer drives, material handling equipment and processing plant drives where reliable torque multiplication and long service life are essential. EVER POWER’s SL series inline planetary gearbox combines competitive pricing with 18-month warranty coverage and faster delivery than typical European OEM lead times.

Working Principle
The EP-SL1801 operates on the epicyclic planetary gear principle. A single planetary stage is coaxially arranged within the sealed housing. The input sun gear meshes simultaneously with multiple planet gears orbiting within a fixed ring gear, distributing the load across all contact points simultaneously. This load-sharing principle is why planetary units achieve significantly greater torque density than parallel-shaft designs of equivalent housing diameter. A precision-ground output shaft or hollow bore transmits the multiplied torque to the driven machine with minimal backlash.
Core Advantages
|
● 18,000 Nm Rated Torque
Full rated output torque for demanding continuous industrial duty cycles. |
▲ Single-stage Efficiency
Maximum efficiency single mesh path for the required application. |
|
◆ Brevini SL1801 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
The housing is precision-cast from GGG50 ductile iron and machined to H7 bore tolerances. Planet gears are manufactured from 20CrMnTi case-hardening steel, carburised to 0.7-1.0 mm case depth and profile-ground to DIN 5 accuracy. The output shaft is supported by back-to-back tapered roller bearings pre-loaded at the factory for zero axial play under combined radial and axial loads. All external shaft seals are FKM fluoroelastomer rated for synthetic gear oil service at up to 120 degC. External coating is two-coat epoxy primer + polyurethane topcoat, 480-hour salt spray rated.
Typical Application Scenarios
| Industry | Application | Key Benefit |
|---|---|---|
| Mining | Belt conveyor head pulley drive | High-efficiency 2-stage minimises heat generation in underground gallery. |
| Cement | Raw meal screw conveyor | High torque for dense raw meal transport at slow speed. |
| Chemical | Mixer agitator drive | Reliable torque for continuous viscous product mixing. |
| Steel | Roll table drive | Consistent speed for hot-rolled bar transfer between mill stands. |
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: 3:1 – 12:1.
- Stage Count — 1-stage provides ratio range 3:1 – 12:1. 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: Can the gearbox be mounted in any orientation?
A: Yes for units with oil-bath lubrication. The sealed housing maintains lubrication effectiveness in horizontal, vertical shaft-up, vertical shaft-down, and inverted mounting positions without modification.
Q: What backlash is standard?
A: Standard backlash is <= 8 arcmin for 1-stage and 2-stage units; <= 10 arcmin for 3-stage and 4-stage units. Reduced backlash options (<= 5 arcmin for 1-stage, <= 6 arcmin for 2-stage) are available for precision servo applications.
