SKF FX Keyless Bushings Introduction SKF FX Keyless Bushings are designed to secure gears, couplings and pulleys to a shaft using mechanical friction rather than using traditional keyways, splines or an interference fit. In general, the size of a shaft is dependant on a number of factors. If splines or keyways are cut into a shaft, the shaft is weakened and a larger-than-necessary shaft must be specified. If, however, the objective is to reduce shaft size, weight, machining costs and installation time while improving accuracy and reliability, SKF FX Keyless Bushings are an excellent...

About SKF FX Keyless Bushings Minimum hub diameter calculation SKF FX Keyless Bushings are designed to create an interference fit with uniform contact pressure on shafts and components that must be fixed to the shaft. The design offers true zero backlash installation and has none of the problems associated with keyways. SKF FX Keyless Bushings make it easy to mount components with a cylindrical (non-tapered) bore to standard, plain shafting and can even be mounted over an existing keyway if necessary. These bushings, which can accommodate wide component tolerances, can considerably reduce...

SKF – the knowledge engineering company From the company that invented the selfaligning ball bearing more than 100 years ago, SKF has evolved into a knowledge engineering company that is able to draw on five technology platforms to create unique solutions for its customers. These platforms include bearings, bearing units and seals, of course, but extend to other areas including: lubricants and lubrication systems, critical for long bearing life in many applications; mechatronics that combine mechanical and electronics knowledge into systems for more effective linear motion and sensorized...
