Fasteners get to grip with hubs

Fastening rotating components to shafts has become easier with the publication of the new 96-page "Handbook of Fairloc components, the integral fastener".

Fastening rotating components to shafts has become easier with the publication of a new 96-page catalogue "Handbook of Fairloc components, the integral fastener, D242" by Sterling Instrument and Stock Drive Products (ISO 9001 registered).

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.

Here is how it works.

Two slots are machined into the hub, one oriented radially, the other angularly, to create a transverse wedge which remains attached to the solid portion of the hub on one side.

The resultant cantilevered clamping section has a tapped hole to accept a cap screw which passes through a clearance hole in the solid portion of the hub, and into a threaded hole in the transverse wedge section.

As the screw is tightened the cantilevered section clamps the shaft securely.

The screw can be tightened and released repeatedly without marring the shaft or affecting its torque transmitting abilities.

The 3405 products in the catalogue include inch and metric Fairloc: hubs, spur gears, timing belt pulleys, couplings, shaft extenders, shaft collars, and dials.

Featured in the catalogue are timing belt pulleys which are shown in six pitches from 0.080in through 5.08mm.

The hub gears in the catalogue represent the largest single product type and are shown in 120, 96, 80, 72, 64, 48, 32 and 24in diametral pitches and in modules 0.5, 0.8, and 1.

All products are available from off-the-shelf stock for immediate shipment.
