EXB Series Right Angle Bevel Helical Planetary Gearboxes
STM Gearboxes
The STM EXB Series merges the benefits of planetary, bevel, and helical gearing into a single right-angle gearbox, providing unparalleled torque density and precision. Its multi-stage design shares loads across multiple planets, delivering exceptionally high shock-load resilience in a compact footprint. Ideal for heavy equipment requiring both speed reduction and right-angle output, EXB gearboxes excel in high-precision indexing and slewing applications. Hardened internal components and precision bearing systems ensure minimal backlash and long service life. Modular input and output flanges accommodate IEC or NEMA motors and hydraulic drives. Condition-monitoring ports support predictive maintenance programs, reducing unplanned downtime.
EXB Series Features
EXB units achieve efficiencies up to 95% per stage, with torque ratings to 310,000 Nm. Ratios span 10:1 to 2,600:1 through combination stages. Case-hardened planetary gears, precision bevel-helical output gears, and high-load bearings resist shock and fatigue. Sealed housings with breathers allow safe operation in dusty or wet conditions. Multiple output shaft and flange options enable direct mounting to driven equipment. Integrated grease injection points simplify upkeep, and optional sensor ports support vibration and temperature monitoring.
EXB Series Applications
- Slewing cranes and booms
- Rotary kilns and tumblers
- Heavy-duty turntables and indexing
- Wind-turbine pitch and yaw drives
