The new Componex WINstub product line is a low-cost, smart alternative to thru-shafts for dead-shaft idler rolls.  Its a new way of mounting idler rollers: they are available as a HUBstub or a NUBstub . Traditional thru-shafts are very difficult to install and remove from a fixed framework that is fully assembled.  HubStub and NubStub can retract into the idler roller to make installation easy.  WINstubs are a fraction of the weight of a thru-shaft, which makes installation fast and easy. The WINstub product line is made of 1045 hard chrome plated and are ground and polished, the same material as WINshafts.

NUBshaft, a thru-shaft eliminator

By eliminating the thru-shaft we also eliminate the potential of excessive bending of long and slender shafts.  At higher idlers speeds, those type of shafts can go into resonant frequency whip.  This is a very dangerous up and down vibration that can cause machine damage and injury to machine operators.  WINstubs do not go all the way through the roller, so they will not go into this up and down motion at high speeds.  The result is safer equipment.
