Bearing clearance adjustment
Assemble in two groups in the same direction, with Bearing assembly accuracy of 0.006 ~ 0.014mm, clearance adjustment, pre tightening adjustment of 0.006mm and fit clearance of 0.001 ~ 0.004mm
Single row tapered roller bearing
Features: it is mainly applicable to bear the combined radial and axial load (mainly radial), and the large cone angle can also bear the combined radial and axial load dominated by axial load.
The bearing is a separate bearing, which can adjust the radial clearance and axial clearance of the bearing during installation and use, or pre interference installation.
Applicable occasion: on the shaft with low speed and good rigidity and large axial and radial load, such as helical gear shaft, the model indicates: example 30202 (imported)
needle bearing:
It is divided into needle roller bearing with inner ring (74000 type) and needle roller bearing without inner ring (84000 type).
Model representation: example ina Zarn2572-tu-ana gemany02 / B07 → shaft bore φ 25, outer circle φ 72。
One way thrust ball bearing (8000 type) and two-way thrust ball bearing (38000 type) are commonly known as plane bearings.
Sliding bearing: usually copper shaft sleeve (hydrostatic bearing, commonly known as floating bearing)
Selection of bearing type
Bearing load:
① Ball bearing shall be preferred for small or medium load (because the main components of ball bearing are in point contact)
② Roller Bearing shall be selected for those with large load (capable of bearing large load and impact load, with small deformation after bearing)
