Spherical roller bearings, as shown in the figure, EA type, high load capacity design of C type, CD type, CA type. Design, EA type, C type, CD type for stamping cage, CA type copper alloy car cage. EA type bearings with high load capacity, low torque special.
Type EA standard design with oil hole oil tank, for other types, in order to supply lubricant, can also set the oil groove and hole, the bearing diameter is less than 180mm, if you need an oil tank oil hole, please in to the NSK when ordering in bearing type superscript E4, for bearing outside diameter greater than 180mm, the standard design for oil tank and oil holes (bearing with E4).
in addition, the use of oil tank, oil hole bearings, because the bearing tank depth is limited. Therefore, if the inner diameter of the casing is also provided with an oil tank, the utility model is more effective.
