NSK Spherical Roller Bearings , Cylindrical Bore Bearings 22213EAE4 ,D=65
|Basic Load Ratings
DESIGN, TYPES, AND FEATURES
Various types of high load capacity spherical roller bearings are available. Types EA, C and CD have pressed-steel cages, and type CA has machined-brass cages. EA-type bearings listed here are classified as NSKHPSTM bearings, which offer particularly high load-carrying capacity, high limiting speeds, and superior performance under high-temperature operating conditions up to 200 °C.
An oil groove and holes are located in the outer ring to supply lubricant, and the bearing numbers are suffixed with E4.
To use bearings with oil grooves and holes, an oil groove should be located in the housing bore since depth for the groove in the bearing is limited. The dimensions of the oil groove and number of holes present are listed in Tables 1 and 2.
When bearings with a hole for a locking pin to prevent outer ring rotation are required, please contact NSK.
