45 other products Parts Network established company trading sales in Japan NSK Spherical roller bearings, on the last NSK spherical roller bearings have high load capacity design of EA-, C-, CD-, CA-based. Design, EA-, C-, CD-as stamping cage, CA-based copper alloy machined cage. EA type bearings with high load capacity, low torque specialty. EA type is of a slewing ring design tank hole, for other types, in order to supply lubricant tank and the hole can also be set, for the bearing outside diameter less than 180mm, with a tank hole if needed, then to the NSK when ordering, marked on the bearing type E4, for diameter greater than 180mm bearings, the standard design for the band grooves and oil holes (bearing model with E4).
In addition, the use of tanks with oil hole of bearing, because the bearing groove depth is limited. Therefore, if the housing is also provided on the inner diameter of the groove is more effective.
Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.
