Plane bearing, also known as thrust bearing; It is a unit composed of a plane cage assembly with a rolling body and a plane washer. Common rolling bodies include needle, roller, ball, etc,
Plain bearing action
Needle roller and cylindrical roller plane thrust bearing, the rolling body is guided by the plane cage. Generally used in combination with DF bearing washers of different series;
The selection of cylindrical roller or needle roller for plane bearing can increase the contact length, so that the bearing can obtain high load and high stiffness in a small space. At the same time, if the surface of the part can be used as a raceway surface, the use of the plain bearing can save the washer,
The high-precision needle diameter tolerance of plane thrust needle roller bearing is 0.002mm, which can ensure uniform load distribution. Using the shaft to guide the plane needle roller and cage assembly, lower circumferential speed can also be obtained at high speed.
The plane bearing is composed of a plane cylindrical roller and cage assembly, a bearing seat locating ring and a shaft locating WS. The plane cylindrical roller bearings 893, 874 and 894 series can also be used at higher loads.
The plane bearing mainly bears axial load during assembly, and the following points shall be noted during installation:
(1) Distinguish the tight ring and loose ring of the bearing.
(2) Identify the stationary parts of the mechanism.
(3) The non-bearing loose ring is always on the end face of the stationary part.
