EP-SL4002 2-Stage Inline Planetary Gearbox
Brevini Riduttori SL4002 Compatible Replacement | EVER POWER
When a Brevini SL4002 needs replacement, EVER POWER’s EP-SL4002 delivers a dimensionally compatible solution at a fraction of the OEM cost. This 2-stage inline planetary gearbox produces approximately 4,000 Nm output torque from a sealed IP65-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-SL4002 from EVER POWER offers a cost-effective alternative backed by ISO 9001:2015 quality management and CE certification.

Принцип роботи
Inside the sealed, oil-bath lubricated housing of the EP-SL402, 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.

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

Часті запитання
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.
