Roller and Bearing Replacement Services

Your rotary kiln’s rollers may damage due to misalignment, excessive load or poor material quality. A shaft crack, small pittings or bigger surface cracks might be the main reason.

Our supervision services for roller and bearing replacement starts with inspection of the old roller to find out the possible causes of the damage and confirmation of replacement. Then we inspect the new roller’s shaft surface quality and diameter to compare. Once we dismantle the old roller we inspect the old bearing to decide if it needs to be replaced and inspect/prepare the new bearing. After scrubbing the new bearing and place all in the housing, we move the roller to it’s new calculated position.

Once the kiln starts rotating, we follow the new bearings’ reaction and perform the correcting fine adjustments. For both the bearing temperature and kiln’s axial migration periods.

Highly Damaged Roller

For any reason (shaft and/or surface cracks) any of your rollers may become unusable over time and you may need to replace the whole roller including the bearing or you may decide to keep the bearing but replace only the roller.

High Bearing Temperature

You may measure high bearing temperature values due to friction between the roller shaft and the bearing and may request to replace only the bearing before it completely damages the roller shaft.

Bearing Preparation

Despite all the matching dimensions; a new bearing should be scrubbed precisely for a proper shaft relation (at required standarts) by creating efficient oil flow and oil film to avoid any unexpected friction.

Positioning the Roller

The diameter of old and new rollers should be compared. The required position of the new roller should be calculated and the roller should be placed carefully to its required position to keep the tyre center at the same level.
