SKF keyless bushings are designed to secure components such as gears, couplings and pulleys to a shaft using mechanical friction rather than using traditional keyways, splines or interference fits that often require sophisticated broaching or milling techniques of the shaft. With FX Keyless bushings these operations can be done with a minimum amount of machining This saves time and can significantly reduce production costs, when compared to using traditional connections, such as interference fits, keyways, splines, keyed bushing systems, QD and tapered bushings.

FX Keyless bushings create an interference fit with uniform contact pressure between shafts and the components that are fixed to the shaft The near perfect 360-degree grip on shaft and component bore offers true zero backlash installation and eliminates shaft damage and the possibility of fretting corrosion.
