In some cases there may be insufficient space available to mount the lower half of the support pedestal during bearing replacement, unless the shaft itself can be lifted, so the maintenance time can be very protracted unless a more innovative design of split roller bearing support pedestal is available.
Making the right choice!
According to Quinteros, overall design cost is lowered because less material is needed to accommodate a needle roller bearing of a certain shaft size.
