Sumitomo Drive Technologies CHHJ-4135Y-29 Gear Reducer

Sumitomo Drive Technologies SM-CYCLO CHHJ-4135Y-29 Gear Reducer is a Cyclo-type power transmission unit designed for compact, high-torque drive applications. The CHHJ-4135Y-29 model provides a 29:1 reduction ratio, reducing input speed while multiplying output torque to meet demanding loads. It is specified for a 7.09 horsepower input at 1,750 RPM and offers an output torque rating of 6,860 lb-in, aligning with typical industrial gearing requirements in space-constrained equipment. This reducer sits within Sumitomo's SM-CYCLO family, combining a robust Cyclo drivetrain in a sealed housing designed for reliable operation in harsh environments. The CHHJ suffix identifies the specific size/configuration within the Cyclo product line, supporting precise mating with compatible motors and mounting arrangements in automation and material handling systems. With its combination of modest footprint, fixed reduction ratio, and proven torque delivery, the CHHJ-4135Y-29 is suited to applications where consistent speed reduction and torque transfer are essential in compact machinery.
