Spherical roller bearings, as shown in the figure, are available in types EA, C, CD, and CA with high load capacity design. In design, EA type, C type, CD type are stamping cage, CA type is copper alloy car cage. EA type bearings have the characteristics of high load capacity and low torque.

The standard design of EA type is equipped with an oil hole and an oil groove. For other types, in order to supply lubricant, an oil groove and an oil hole can also be set. When ordering, mark E4 on the bearing model. For bearings with an outer diameter greater than 180mm, the standard design is with oil groove and oil hole (bearing model with E4).
In addition, when bearings with oil grooves and oil holes are used, the depth of the oil groove of the bearing is limited. Therefore, it is more effective if the oil groove is also provided on the inner diameter of the shell.

Bearing application areas:

Steel equipment, mining machinery, engineering machinery, papermaking machinery, wind turbines, working machinery, gear units, electric motors (motors), pumps and compressors, injection molding machines.
