Abstract

A shredder includes a cutting unit frame and a cutting shaft rotatably supported in the cutting unit frame and carrying a multiplicity of cutting disks, rotatable with the cutting shaft for shredding an item in cooperation with a further tool. The cutting unit frame has two opposing side parts extending parallel to the cutting shaft and two fronting parts extending transversely to the side parts and the cutting shaft. Each fronting part has upper and lower fronting part elements attached to one another and extending between and separately attached to the side parts and internally capturing one of two bearings therebetween such that the bearings rotatably mount the cutting shaft in the cutting unit frame and are removable with the cutting shaft upon removal of only the upper fronting part elements from the cutting unit frame without bringing the cutting unit frame out of adjustment.
