SITI Helical Gearbox
The SITI helical gearbox series delivers high-efficiency power transmission with torque capacities ranging from 30 Nm to 10,000 Nm. Featuring precision-ground helical gears with 20CrMnTi alloy steel construction, these units achieve up to 97% mechanical efficiency while operating at noise levels below 63 dBA. The rugged cast iron housing GG25 grade provides exceptional thermal stability and vibration damping, with optional aluminum alloy versions for weight-critical applications. Available in foot-mounted, flange-mounted, and shaft-mounted configurations, these gearboxes support IEC standard motor interfaces and offer ultra-precise models with backlash as low as 2 arc-minutes. The triple-lip sealing system ensures IP67 protection against dust and water ingress, while the advanced lubrication system extends maintenance intervals to 30,000 operating hours.
SITIs innovative gear design incorporates carburized and tempered gear teeth 60-62 HRC with profile grinding for maximum durability under continuous heavy loads. The optimized bearing arrangement exceeds AGMA load capacity standards by 15-20%, ensuring reliable performance in demanding conditions. These gearboxes operate efficiently across an extended temperature range -25°C to +110°C and feature corrosion-resistant surf
