Products Introduction
Sprinkler Gearbox serves as the vital transmission component for center pivot irrigation systems. Working together with drive motors, it powers tower wheels to maintain steady circular movement of sprinkler spans. It is engineered as a direct replacement for original gearboxes of Valley, Zimmatic, Reinke and other mainstream irrigation brands. Standard reduction ratios 50:1 & 52:1 are available with unified 2.25" output shaft, rated torque ranging from 7909 Nm to 10170 Nm. Optimized for harsh outdoor farm conditions including muddy terrain, slopes and wide temperature variation, it fits both short and long-span agricultural irrigation projects.
Product Characteristics
High-precision housing machining technology
Precision milling on housing mating surfaces ensures uniform clearance to prevent seepage. Integrated casting delivers high rigidity, resisting deformation under load and maintaining consistent gear meshing accuracy over time.
Long-lasting anti-corrosion coating
Weather-resistant paint protects housing against rain and chemical fertilizer mist in farmland, slowing rust formation and maintaining structural integrity under long-term outdoor exposure.
Standard external mounting layout
Flange hole pattern follows standards of mainstream European & American irrigation equipment. No on-site reaming or bracket modification required, offering great compatibility for machine retrofitting and new assembly.
Product advantages
High Versatility & Easy Replacement
Standardized output shaft and gear ratios, mounting flanges consistent with OEM units. Direct on-site installation without frame modification and shorten field downtime.
Strong Load Capacity for Complex Terrain
High torque design easily handles startup loads on slopes and wet ground, lowering risks of overload failure, ideal for non-stop irrigation on large farms.
User-Friendly Maintenance to Cut Operational Cost
Optimized internal oil circuit and heat dissipation slow down lubricant aging, extend maintenance intervals and reduce recurring labor and spare part expenses.

FAQ
Q:How often should gear oil be replaced?
A: It is recommended to change gear oil after each irrigation season. For year-round heavy continuous operation, replace oil every 6 months to prevent oil deterioration and internal wear.
Q:What key points should be noticed during gearbox installation?
A:Clean the mating surface of output shaft before installation; fill lubricant to specified level; ensure the breather valve is unobstructed to avoid excessive internal pressure and oil leakage.
Q:Can the gearbox run forward and reverse continuously?
A:This sprinkler gearbox supports forward and reverse cyclic operation. However, frequent rapid direction switching is not suggested, as repeated impact will accelerate gear wear and shorten service life.
