Installation of TIMKEN radial bearing spherical roller bearings
Before installing TIMKEN radial bearing spherical roller bearings, the installation method, sequence and tool preparation should be studied. Tools for safe cleaning and installation environment should be prepared.

When installing TIMKEN radial bearing cylindrical hole spherical roller bearings, we often use tapping installation. This method is used for the installation of TIMKEN spherical roller bearings with inner diameter less than 80mm, small bearings with Mandarin interference, press the sleeve The tube is placed against the inner ring of the bearing and the center of the sleeve is tapped。

There are also installation methods for installing TIMKEN radial bearing spherical roller bearings with press installation and heating with bearing heaters. Please contact us directly for specific methods.

Disassembly of TIMKEN radial bearing spherical roller bearings
When the TIMKEN radial bearing spherical roller bearing is regularly inspected, it is necessary to disassemble the bearing to see if the bearing is running abnormally. In general, the disassembly sequence and installation sequence of the TIMKEN radial bearing spherical roller bearing are reversed. For the used bearing, the bearing used for disassembling the bearing is used. The strength is greater than when installing. . A dedicated puller can be used.

Analysis of Causes and Countermeasures for Damage of TIMKEN radial bearing Spherical Roller Bearings
1. Phenomenon and cause of TIMKEN radial bearing
Damage to the bearing due to exceeding the specified centering angle
Countermeasures:
When installing large TIMKEN radial bearing spherical roller bearings, use the flat ruler on the inner ring and the outer ring end face, measure the eccentric angle by changing the angle, and adjust the inner and outer ring to the same plane, then insert into the bearing seat and use the flat ruler. The amount of eccentricity and axial misalignment are measured on the inner and outer rings.

2, phenomenon and cause of TIMKEN radial bearing
The installation interference is too large, causing the inner ring to break.
Countermeasure: For the conical hole spherical roller reference installation, the interference is too large, causing the inner ring to axially break and the crack to be zigzag. Note that the interference between the control shaft and the inner diameter of the bearing should not exceed 7/10000 of the journal.

3. Phenomenon and cause of TIMKEN radial bearing
Early rolling wear caused by poor lubrication
Countermeasure: For the short-term internal wear failure caused by the unreliable sealing, which causes foreign matter such as dust and kerosene in the bearing, it is necessary to pay attention to check the seal of TIMKEN spherical roller bearing, and replace the failure seal in time to ensure sufficient lubrication and reliable sealing.
