NUKR series cam follower/curve roller
Model NUKR curve roller bearing has the double-row roller structure. As same as parallel roller bearing, the outer ring is guided axially by rolling body. The cover pressed in outer ring and the shoulder constitutes the high-efficient gas seal.
This kind of curve roller bearing can withstand the heavy load and the shock axial load because it is guided axially by roller.
NUKR .. A design cam followers (fig 1) are based on double row, full complement cylindrical roller bearings without an integral flange between the two roller sets. The stud head and pressed-on flange ring guide the outer ring axially via the roller sets. This enables NUKR .. A design cam followers to accommodate relatively heavy axial loads that are induced when operating in an inclined or tilted position.
A sheet metal angle ring is pressed into the outer ring shoulder on both sides to form an effective labyrinth seal.
