EP-SC25004 4-Stage High-Ratio Planetary Gearbox
Brevini Riduttori SC25004 Compatible Replacement | EVER POWER
The EP-SC25004 is EVER POWER’s independently engineered 4-stage high-ratio planetary gearbox, designed as a direct replacement for the Brevini riduttori SC25004. Delivering approximately 25,000 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 SC series compact planetary gearbox combines competitive pricing with 18-month warranty coverage and faster delivery than typical European OEM lead times.

Принцип роботи

The EP-SC2504 operates on the epicyclic planetary gear principle. Four sequential planetary stages are 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.
Основні переваги
|
● 25,000 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 SC2504 Direct Fit

★ 18-Month Warranty
EVER POWER’s 18-month warranty exceeds the 12-month standard of most European OEM suppliers. |
Структура та технологія матеріалів

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.
