Reusing bearings

To determine if a bearing can be reused, it must be inspected carefully. A detailed inspection requires disassembling the bearing. Angular contact ball bearings cannot be disassembled without damage unless special tools are used. Cylindrical roller bearings can only be partly disassembled.
SKF does not recommend reusing super-precision bearings. In most cases, the risk for unplanned downtime or unsatisfactory performance outweighs the cost of new bearings.
Bearings should be dismounted carefully, regardless of whether they will be reused, because careless dismounting could damage associated components. Also, if the bearing is dismounted carefully, it can then be used for condition and damage analysis if required.
