Abstract
A pump insert () for supporting a rotor () of a pump comprises an annular resilient support () for engaging the body () of the pump, the support () extending about a rolling bearing () having an inner race () for engaging the rotor (), an axially preloaded outer race () fixed to the support (), and a plurality of rolling elements () located between the races. During assembly, the rolling bearing () can be accurately positioned within the support () so that there is a very low tolerance stack-up when the insert () is fitted to the rotor (). Consequently, the position of the rotor () will hardly change, if at all, when the rolling bearing () is replaced during servicing of the pump.
