Zero-Max Phas-Lok adjusting hubs provide a fast and easy method for changing the phase relationship of components in a power transmission system.

Phas-Lok compensates for required timing changes in a system. They provide an accurate, mechanical adjustment within a 24° range (±12°). They eliminate the need to disconnect or remove drive components in order to reposition or re-synchronize drive components.

Mounted in a system, Phas-Loks provide a reliable position control that does not loosen or slip during equipment start up and shut down. Without any system disassembly, the phase adjustment can be made quickly on the machine with accuracy using ordinary hand tools.

“Phas-Loks are a time-proven device for fine tuning timing adjustment in a power transmission system,” reports Robert Mainz, Zero-Max sales manager.”

Available in 3 sizes with bores ranging from 1/2 inch to 2-1/2 inches. Also available in metric bore sizes and with a variety of split taper bushings.
