Mounting Bearings

Prevent 16% of premature bearing failure
Around 16% of all premature bearing failures are caused by poor fitting, usually using brute force, and being unaware of the availability of the correct mounting tools and methods. Individual installations may require mechanical, heat or hydraulic application methods for correct and efficient mounting. Professional fitting, using specialised tools and techniques, is another positive step towards achieving maximum machine uptime.

Dismounting Bearings

Reduce the risk of personal injury and bearing & shaft damage
Dismounting bearings can be hazardous and demanding task. Selecting the correct tool is therefore of utmost importance for reducing the risk of personal injuries.

One reason for dismounting an "old" bearing is to replace it by a new one. When dismounting such a bearing, care must be taken not to damage the shaft while dismounting, which can result in compromising the machine's efficiency.

Another reason for dismounting bearings is for maintenance or replacement of other machine's components. These dismounted bearings are mounted again, unless they are damaged during dismounting. To enable the reuse of the same bearing, care must be taken when selecting dismounting methods and tools.

Individual applications may require mechanical, heat or hydraulic dismounting methods for safe, correct and efficient dismounting. Professional dismounting, using specialised tools and techniques, is another positive step towards achieving maximum machine uptime.
