Newspaper Press Core Shafts

SATGURU manufactures air and mechanical core shafts for various newspaper presses such as Goss, Harris, King and others, along with shafts for various spillers such as Martin, Enkel, Butler and others.

Core Shafts can be supplied in Steel Body for heavy use, Aluminum for small rolls for lighter weight, and Carbon fiber. Carbon fiber is not usually recommended for Newspaper presses due to the rough use encountered in their field. Hardened journals for running on cam-followers and rollers are standard. Journals are manufactured from high strength 40 Ht steel and induction hardened as necessary in the wear area. Mechanical shafts are recommended for very high speed use, since they hold the rolls more concentric, reducing roll bounce. Mechanical shafts are more cumbersome to handle and are usually heavier than an air shaft.

Journals are made on our modern machines according to a precise tolerance. Low maintenance Lug type shafts are recommended for standard Press use. It gives the best grip with the least amount of maintenance required.

It is also the quickest to replace bladders when required .SATGURU air shafts have a rubber sleeve protecting the bladder. The sleeve holds the lugs in place while the bladder is removed and replaced, reducing any downtime to the minimum.
