The insert bearing also is named pillow block bearing, it is actually a variant of the deep groove ball bearing. Its outer diameter surface is spherical, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of centering. The insert bearing is mainly used to bear the combined radial and axial load, and it is not suitable to bear the axial load alone.
The insert bearing is more convenient to use than the general deep groove ball bearing. Its main characteristics are simple loading and unloading and adjustable center. The standard tolerance of the insert bearing is: adding and subtracting inside and adding tolerance to the inner diameter, so as to ensure the lightness when matching with the shaft; each set of insert bearing is not used separately, and it must be equipped with the inner whole installation of the bearing seat, and the insert bearing seat is not used alone It has various shapes, so it is suitable for various structural positions after overall coordination. insert bearings can be divided into three types according to the locking mode with the shaft.
Insert bearing with forcing screw
The codes are: uc200 series (light series), uc300 series (heavy series), and UB (sb) 200 series of deformation products. If the environmental load is small, uc200 series is generally selected, otherwise uc300 series is selected. Generally, there are two jacking screws on the bearing, and the included angle is 120 degrees. Its characteristic is that when it is matched with the shaft, it is jacked on the shaft to play a fixed role. However, the vibration range of the matching environment must be small. This kind of spherical ball bearing is widely used in textile machinery, ceramic machinery and other manufacturing industries.
Tapered insert bearing
The codes: uk200 series, uk300 series. This kind of insert bearing ball bearing with inner diameter of 1:12 taper inner hole should be used together with tightening sleeve. The characteristics of this kind of insert bearing ball bearing are: it can bear more load than that of insert ball bearing with jacking wire. For example, the inner diameter of the same type of tightening sleeve is smaller than that of the insert ball bearing with forcing screw. For example, the inner diameter of uc209 is 45mm, and the diameter of the shaft used with it is 45mm, If the bearing is replaced by a tapered insert ball bearing, the bearing with an inner diameter of 45mm can only be selected, while the tapered insert ball bearing with 45mm sleeve only has uk210 (of course, uk310 can be selected if the load is higher). Therefore, the load of uk210 should be greater than that of uc209.
Insert bearing ball bearing with eccentric sleeve
Its codes are: UEL200 series, UEL300 series, SA200 series. The main feature of this kind of insert ball bearing is that the upper end of the bearing has certain eccentricity, and the eccentric sleeve with the same eccentricity fits with it. This kind of bearing can also be said to be a special bearing, because it is mainly used in agricultural machinery (harvester, straw returning machine, thresher, etc.), this kind of insert bearing ball bearing is mainly used in the structure with violent jump, and the coordination of eccentric structure can effectively reduce violent jump.
Seals of the bearing
Compared with other ordinary bearings, the insert bearing ball bearing also has a feature of double-layer seal, because the operating environment of general insert ball bearing is more stringent, especially for agricultural machinery bearing, and the double-layer seal ensures that dust is not easy to enter into the groove. China SKET company is a professional bearing manufacturer and supplier, the company has developed three lip sealed insert bearing, which greatly enhances the dust-proof ability and prolongs the service life of the bearing.
