ProductDescription : Bearings
：Planar thrust bearings achieve high axial loads and high stiffness in a small space.
Planar thrust bearings are used in a wide range of applications: automobiles motors
electrical appliances machinery furniture toys printers construction machinery
sewing machines packaging machinery printing machinery food chemical machinery
machine tools textile machinery fitness equipment electronic products etc.
Pay attention to the following points during installation:
1. Thrust ball bearings can only withstand a single axial force and cannot withstand radial forces.
2. Not suitable for high speed operation.
3. Distinguish the tight ring and loose ring of the bearing (the inner diameter of the loose ring is larger).
4. Distinguish the static parts of the mechanism.
5. In any case the loose ring of the bearing should always be placed on the end face of the stationary part!!!!!!!!!!!!!!
1. Why do the bearings I received have shaking?
The clearance of the bearing is related to the play.
The default is the standard C0 clearance which is usually 3-18um.
The corresponding principle is shown in the figure below.
If you don't need to shake please choose C2 small clearance bearing.
If you have any questions please contact us before purchasing.
2. What is the accuracy of ABEC-1?
ABEC is the American ANSI standard.
The corresponding German DIN standard and international ISO standard are as follows:
