The food strainer shaft bushing fits between the drive shaft and the metal housing. The bushing is not supposed to turn. A shaft seal will keep liquids from leaking between the shaft and the nylon bushing. If your strainer is leaking between the metal housing and the nylon bushing then the bushing may be damaged and need to be replaced.
