Types of Outer Ball Cylindrical Roller Bearings: 1 Outer Spherical UC Bearings with Set Screws; 2 Outer Spherical UK Bearings with Tapered Holes The center plus the bearing seat name, such as the outer ball cylindrical roller bearing with set screw UC205 with vertical seat is called UCP205. Due to its strong interchangeability, the outer ball cylindrical roller bearing with a seat can be freely assembled on the same specification and different shapes of the bearing seat. The outer ball cylindrical roller bearing is actually a variant of the deep groove ball bearing, which is characterized by The outer diameter surface of the outer ring is spherical, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of centering. Although its basic performance should be similar to that of deep groove ball bearings, because these bearings are mostly used in relatively rough machinery, the installation and positioning are not accurate enough, the axis alignment between the shaft and the seat hole is poor, or the shaft is long and deflected. In the case of large and other, and the bearing itself is not high enough precision, and some structures are also rough, so the actual performance of the common performance should be marked with a considerable discount compared with the deep groove ball bearings of the same specification. For example, the outer ball cylindrical roller bearing with top wire is applied to the through shaft with large stiffness difference and large deflection. This kind of bearing has sealing rings on both sides, which can strictly prevent the intrusion of dirt. Need to clean, do not need to add lubricant, when the top screw on the protruding end of the inner ring of the bearing is fastened on the shaft. The allowable axial load shall not exceed 20% of the rated dynamic load. The performance of the outer ball cylindrical roller bearing with eccentric sleeve is basically the same as that of the outer spherical bearing with top wire, but the top wire is not on the inner ring, but on the eccentric sleeve. The inner hole of the outer ball cylindrical roller bearing with tapered hole is a tapered hole with a taper of 1:12, which can be directly installed on the tapered shaft, or installed on the light shaft without shoulder with the help of an adapter bushing, and can fine-tune the bearing travel. gap.
