Slitter knife holder

摘要

A holder for a circular cutting knife for slitting sheet metal, comprising a precision ground mounting shaft for attaching the cutting knife, the mounting shaft rotatably retained within a housing by engaging sets of high precision ball bearings. The ball bearings are located within the housing by a set of precision ground bearing spacers and precision ground bearing retainers. The bearings are preloaded in the housing to minimize longitudinal movement of the mounting shaft during operation. Additionally, the housing containing the bearings is tapered on one surface so that the cant of the knife blade can be adjusted by reversing the orientation of the housing.
