†
Flexible couplings are designed to accommodate changes in operating conditions. Coupling life expectancy between initial alignment and maximum operating limits is a
function of load, speed and lubrication. Limits shown are extremes and should not be combined. Application requirements in excess of 1/4° misalignment per flex-half
coupling should be referred to Factory for review.
‡ NLGl #0 grease must be used when speeds are below minimum shown.
