nylon cage flat needle bearing for Printing Machine FF2010
Linear Flat Rollers This bearing type composed of a needle roller and flat cage assembly (needle rollers are configured in the flat cage) ensures smooth reciprocating motion with less friction coefficient.
For Type FF, the polyamide resin cage has a dovetail joint groove on its both ends so that several cages can be jointed together into one unit.
For Type F..ZW, two rows of needle rollers are configured in the cage and the cage has an elastic joint on its center so as to enable to bend two rows of flat rollers to any optional angle at the elastic joint by heating them in oil of 70 to 90°C. The two roller rows bent to any optional angle can hold the bent shape unchanged, even under normal operating temperature, by being cooled down for several seconds, with the bending angle held unchanged.
