The thrust ball bearing is a kind of separate bearing; the shaft ring and the seat ring can be separated from the cage and the steel ball assembly. The shaft ring is a ferrule matched with the shaft; the seat ring is a ferrule matched with the bearing seat hole; There is a gap between the shaft and the shaft, the thrust ball bearing can only accept the axial load; the one-way thrust ball bearing can only accept the axial load in one direction; the two-way thrust ball bearing can accept the axial load in both directions, the thrust ball bearing The radial displacement of the shaft cannot be constrained; the limit rotation speed is very low; the one-way thrust ball bearing can restrain the axial displacement of the shaft and the casing in one direction; the two-way bearing can restrain the axial displacement in two directions.
1. Thrust ball bearing (51000 type)
2, two-way thrust ball bearing (52000 type)
3, externally adjustable heart thrust ball bearing without self-aligning seat washer (53000 type)
4, externally adjustable heart thrust ball bearing with self-aligning seat washer (53000 U type)
5, two-way externally adjustable heart thrust ball bearing without self-aligning seat washer (54000 type)
6. Two-way externally adjustable heart thrust ball bearing with self-aligning seat washer (54000 U type)
Thrust roller bearings are used to accept axial and radial combined loads with axial loads; however, radial loads must not exceed 55% of axial loads. Compared with other thrust roller bearings; Low; high speed; and has a self-aligning function. The stick of the 29000 type bearing is an asymmetrical spherical roller; it can reduce the relative sliding of the roller and the raceway during operation; and the roller is long and has a large diameter; the roller Large quantity; high load capacity; usually oil is smooth; single low speed condition can be smooth grease. When drawing and selecting; should be preferred, 80,000 type thrust cylindrical roller bearing, 90000 type thrust tapered roller bearing and AXK type thrust needle roller Bearing; can accept one-way axial load; it can be much larger than the axial load of thrust ball bearing; and it has large rigidity and small axial space. Thrust cylindrical roller bearing and thrust needle roller bearing are suitable for low speed Occasionally; the thrust tapered roller bearing rotates slightly higher than the thrust cylindrical roller bearing. The outer spherical bearing is a kind of bearing unit that connects the rolling bearing with the bearing seat. Most of the special spherical bearings will be Made spherical diameter; and the bearing device with a spherical inner bore together; layout forms; good versatility and interchangeability.
Together; these bearings also have a certain degree of alignment in the depiction; easy equipment; sealing equipment with two layers; can work in harsh environments. The bearing housing is usually cast and cast. The common seat has a vertical seat (P) , square seat (F), boss square seat (FS), boss circular seat (FC), diamond seat (FL), ring seat (C), slider seat, etc. (T).
There are two common types of outer spherical bearings:
l With a set screw outer spherical UC bearing,
2 with a tapered hole outer spherical UK bearing,
The spherical bearing with seat is divided into the bearing core and the bearing seat; in the name of the bearing core plus the bearing seat; if the spherical bearing UC205 with the set screw is equipped with the vertical seat UCP205. With the spherical bearing because of Very interchangeable; the bearing core can be assembled freely in a bearing housing of the same standard
