The use of needle roller bearings continues to annoy printing machine manufacturers with the need for highly accurate jackets and the need for experienced installers to find suitable needle roller groups. To solve this problem, bearing manufacturers have developed roller bearing supports with integrated flanges on the outer ring.

A roller bearing is a type of bearing in which the journal rotates in circumferential contact with many rollers typically mounted on a locating ring. Roller bearings can achieve good accuracy and rigidity through preloading. Also, an inner ring with a taper can be used to arbitrarily adjust the working clearance of the bearing. This solution can fully meet the demand for zero clearance of the printing machine cylinder bearings.
