Fairloc is designed to solve phasing, timing, positioning and frequent removal problems which conventional fastening methods, such as clamps, keyways, pins or set screws, cannot properly handle. The patented system offers several advantages including: built-in overload protection, full use of the bore, easy adjustment, compact self- contained design. With the very economical Fairloc system, the shaft remains smooth. It is also self-contained so there is no additional inventory to stock. The component can be easily adjusted and is fully supported. Our Fairloc Components Catalog D242 includes over 3,400 products in the catalog (both inch and metric) Fairloc: hubs, spur gears, timing belt pulleys, couplings, shaft extenders, shaft collars, and dials. Featured in the catalog are timing belt pulleys which are shown in 6 pitches from .080" through 5.08 mm. The hub gears in the catalog represent the largest single product type and are shown in 120", 96", 80", 72", 64", 48", 32", and 24" Diametral Pitches and in Modules 0.5, 0.8, and 1.
