How to install tapered roller bearings?

 Adjusting axial clearance For the installation of tapered roller bearing axial clearance can be adjusted by adjusting nuts on the journal, adjusting gaskets and threads in the bearing seat hole, or by pre-tightening springs and other methods. The size of axial clearance is related to the arrangement of bearing installation, the distance between bearings, the material of shaft and bearing seat, and can be determined according to working conditions.

For tapered roller bearings with high load and high speed, the influence of temperature rise on axial clearance must be considered when adjusting clearance, and the reduction of clearance caused by temperature rise must be estimated. That is to say, the axial clearance should be properly adjusted to a larger extent.

For bearings with low speed and bearing vibration, no-clearance installation should be adopted, or pre-load installation should be applied. The purpose is to make the tapered roller bearing roller and raceway have good contact, uniform load distribution, prevent the roller and raceway from vibration impact damage. After adjustment, the size of axial clearance is tested with a micrometer.

Advantages：

1. Suitable for the radial and axial loaded.

2. With low and smoothly coefficient of friction.

3. Suitable for dirty corrosion impact load & edge loading.

4. Can be used over a large temperature range.

5. Base material provided good shock absorbing capacity.

6. With low wear rate and long life service.

7. Allows maintenance free and long life operation.
