Sumitomo Drive Technologies CNFJ-4085Y-8 Gearbox

Sumitomo Drive Technologies CNFJ-4085Y-8 is an inline gear reducer in the CNFJ family, designed to be mounted in line with a drive motor to convert high rotational speed into lower output speed with higher torque in compact drive systems. The CNFJ-4085Y-8 variant specifies a 59:1 reduction ratio, delivering substantial torque multiplication within a compact footprint that fits tight installations and preserves motor speed characteristics suitable for small to mid-size driven loads. Built for industrial reliability, this gearbox emphasizes precise gear geometry, a rugged housing, and compatibility with inline mounting patterns, supporting consistent performance under load and long service life in harsh environments. This model is commonly used in space-constrained machinery where dependable torque delivery is critical, such as automated equipment and conveyors, and it represents Sumitomo's commitment to durable, long-life drive solutions. With an inline layout that aligns input and output shafts, the CNFJ-4085Y-8 supports straightforward installation in compact spaces and helps minimize overall machine footprint.
