1. Diversified internal structure design for more industrial demand
Spherical roller bearings, as shown in the figure, have high load capacity design of EA type, C type, CD type, CA type. In design, EA type, C type, CD type are stamped cages, and CA type are copper alloy car cages. EA bearing has the characteristics of high load capacity and low torque.
The standard design of the EA type is provided with oil holes and oil grooves. For other types, oil grooves and oil holes can also be provided for the supply of lubricants. For bearings with an outer diameter less than 180mm, if oil holes with oil grooves are required, When ordering, mark E4 on the bearing model. For bearings with an outer diameter greater than 180mm, the standard design is with oil grooves and oil holes (bearing models with E4).
In addition, when using bearings with oil grooves and oil holes, the depth of the oil groove in the bearing is limited. Therefore, if an oil groove is also provided on the inner diameter of the shell, it is more effective.
2. Adjusted automatically characteristic to withstand large loading
One of the bearings in NSK bearings is a spherical roller bearing. The spherical roller bearings are self-aligning because the center of curvature of the outer ring raceway surface of the spherical roller bearing is the same as the bearing center. Cardiac Function. When the shaft and housing are deflected, it can be adjusted automatically without increasing the bearing load. Spherical roller bearings of NSK bearings can withstand large radial loads and can also withstand certain axial loads. This type of bearing's outer ring raceway is spherical, so it has self-aligning performance. When the bearing is bent or tilted by force, the centerline of the inner ring and the centerline of the outer ring are relatively inclined not more than 1 ° ～ 2.5 °, the bearing can still work. . It can compensate the concentricity error formed with the bearing installation part after the shaft is bent and deformed. The rolling bearing of Japanese NSK bearings will change its bearing capacity, rotation accuracy and friction reduction performance during use due to its own quality and external conditions. In fact, anything in use will reduce its life.
