skf Insert bearings high temperature

Except for the cage and seals, SKF insert bearings (Y-bearings) for high temperature applications correspond in design to standard insert bearings with grub screws in the YAR 2-2F series. The bearings have a shield and a flinger on both sides to prevent the ingress of solid contaminants into the bearing.
The entire surface of the bearing and the shields are manganese phosphated to enhance adhesion of the lubricant to the metal and improve the running-in properties of the bearing. The flingers are treated by pickling. 
The radial internal clearance is a multiple of C5 to prevent the bearings from seizing, even when they cool rapidly.
