Spindle liners are also known as filler tubes, reduction tubes, master liners or sleeves. Here at Hydrafeed, we supply a Master Liner System with every new Barfeed installation. Each Master Liner System is supplied with black acetal bushings. The bushings are bored with the appropriate clearance of the bar diameter to be run. They are designed to support different bar diameters through the headstock of the lathe.

An alternative option to the Master Liner System is dedicated liners. These are supplied without bushings and the bore of the dedicated liner suits the bar diameter required.

Dedicated liners can also be supplied to suit hexagon, square, rectangular and irregular shaped profiles. The profile bar is orientated by the dedicated liner as it feeds through the headstock to align with the lathe workholding.
