Rolling bearing assembly is always a critical issue. The first question that comes to mind after failure of a bearing is that of proper assembly. This is not surprising, since after lubrication previous damage during mounting or handling of rolling bearings is the second most common cause of premature bearing failures.
Heavy and large rolling bearings in particular are not easy to mount and can be damaged by untrained personnel due to carelessness, incorrect transport or simply due to incorrect mounting technology, resulting in premature failure.
The cost of a special repair is high, not to mention the cost and pressure of downtime for the affected equipment.
