Single row spherical roller bearings mounting axial clearance

The mounting axial clearance of single row spherical roller bearings can be adjusted by adjusting nuts on the journal, threads in adjusting gaskets and bearing seat holes, or by pre-tightening springs, etc.
The size of axial clearance for single row spherical roller bearings is related to the arrangement of bearing installation, the distance between bearing and the material of shaft and bearing pedestal, and can be determined according to working conditions.
For single row spherical roller bearings with high load and high speed, the influence of temperature rise on the axial clearance must be taken into account when adjusting the clearance, and the reduction of clearance caused by temperature rise should be included in the estimation. In other words, the axial clearance for single row spherical roller bearings should be adjusted a little larger appropriately.

For single row spherical roller bearings of low rotation speed and bearing vibration, no clearance installation should be adopted, or pre-load installation should be applied.The purpose is to make the roller and the raceway of the self-aligning roller bearing have good contact, the load is evenly distributed, and prevent the roller and the raceway from being damaged by vibration impact.

After adjustment, the size of axial clearance is checked by the dial indicator.The method is to fix the dial indicator on the fuselage or bearing seat, so that the dial indicator contact against the smooth surface of the axis, along the axis around the push axis, the maximum pendulum momentum of the dial needle is the axial clearance value.
Main applications for single row spherical roller bearings: papermaking machinery, reduction gear, railway rolling stock axle, rolling mill gear box bearing, rolling mill roller, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reduction gear, vertical bearing with seat centering.
