We recently had the opportunity to discuss bearing grease lubrication, highlighting the importance of being careful, during preventive maintenance, to evaluate the convenience of possible refills and to monitor possible anomalies in their operation.
Today it 's time to deal with the other main type of bearing lubrication that ad oil .
Oil lubrication
In this regard, let's start by remembering that for a housing with oil bath lubrication it would be advisable to provide an integrated system with an oil level indicator that can more easily guarantee correct maintenance of the oil level when the bearing is not in use, thus reducing the risk of errors arising from “estimates” about whether or not liquid refilling is necessary.
As you can imagine, if the current amount of oil is lower than the normal expected level, you will need to make up the difference. On the other hand, if the system works correctly and there are no hydraulic leaks, the need to intervene in the lubrication issue also decreases.
The need for relubrication depends on what
The need to replace or integrate the oil present in the system where the bearing is located will depend mainly on its operating conditions. In fact, if the bearing is used at a low temperature , in a favorable context where there is no risk of contamination with dust and other dirty elements, relubrication activities will be quite limited and sporadic, making it possible to follow the manufacturer's instructions. On the other hand, if the bearing works at very high operating temperatures, is subject to the influence of external heat sources or is subject to possible frequent contact with dust and other dirt elements, it will be necessary to replace the bearing. 'much more frequent oil.
As for the amount of oil to be inserted into the carcass, it will depend on the specific conditions, therefore it is not possible to express a generic estimate in summary form. Even in this area, it will therefore be necessary to consult the manufacturer's instructions or that of a specific mechanical consultant.
