Interchange check
What must match before substitution
6 checks
Ratio / speedConfirm the replacement produces the required output speed at the actual input speed.
Torque / dutyVerify continuous and peak torque, service factor, shock loading, starts per hour, and thermal duty.
Output geometryMatch shaft or bore diameter, key/spline/bushing, output side, usable length, and allowable overhung/thrust loads.
MountingCheck foot pattern, flange pilot/bolt circle, center height, torque arm, and mounting position.
Input / motorConfirm motor frame, adapter, input shaft or quill, power, brake, encoder, voltage, and frequency.
EnvironmentVerify lubricant, washdown/corrosion requirements, temperature, ingress protection, and hazardous-area needs.
