Pulley interfaceVerify pulley groove profile, pitch diameter range, belt count, alignment, and center-distance/tensioning range.
ConstructionConfirm standard, Red Power, HVAC, cogged, aramid, or other construction requirements instead of using part length alone.
Duty and environmentCheck transmitted power, speed, starts, temperature, oil/chemical exposure, guarding, and current Optibelt limits.
