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 solution.
