Types and Characteristics of NSK Rolling Bearings---Spherical Bearings with Seats
Source: this site     Release time:2021-12-24


NSK Bearing is composed of radial ball bearings, sealing rings and bearing seats of cast iron or stamped steel plates of various structures. The outer diameter surface of the bearing and the inner diameter surface of the bearing seat are spherical structures, so the bearing is self-aligning. The design of the cage and ball inside the ball bearing is the same as that of the deep groove ball bearings of the 62 and 63 series. Both sides of the bearing are equipped with double-layer seals composed of synthetic rubber oil seals and oil throwing rings.
Depending on the type, there are the following fixing methods for the inner ring.
(1) The inner ring is fixed on the shaft by two set screws.
(2) The inner ring is a tapered hole, and the inner ring is fixed on the shaft by the adapter sleeve.
(3) The inner ring is fixed on the shaft by the eccentric sleeve.
NSK Radial Ball Bearing Assembly is a miniaturized combination of bearings, bearing housings, and seals, and standardized components that make up the main parts of the machine, improving versatility and easy-to-use products.
Using the seated radial ball bearing assembly simplifies the peripheral structure of the machine, so it is more rational in installation and maintenance, and because of its self-alignment, it can prevent moment loads caused by installation errors. In addition, since it is easy to install on the machine table and the side wall, it can be used in all places such as frame structures.
Because of the above characteristics, the application field of the seat insert ball bearing assembly has been rapidly expanded, and at the same time, we are also required to have a variety of products with various performances.
NSK spherical ball bearing with seat and both sides of the bearing seat are equipped with seals, so this kind of bearing can be used in heavy industries such as milling machines, steel equipment, casting equipment, electroplating equipment, chemical equipment, construction machinery, transportation equipment, etc. equipment.
