A bearing using an oiling ring as a means of static oil feed must occasionally be serviced by removing the wear particles, grit, and moisture. How is this accomplished?

The correct approach for servicing a bearing that uses an oiling ring for static oil feed is to drain the bottom of the bearing lube oil sump. This process allows for the removal of accumulated wear particles, grit, and moisture that can collect at the bottom of the sump over time. By draining the oil, you effectively clear out the contaminants that can hinder the performance of the bearing and may lead to premature wear or damage.

Draining the sump is essential because it not only removes dirty oil but also allows for the introduction of fresh oil, which is clean and free of contaminants. Adequate lubrication is crucial for the operation of bearings, as it minimizes friction and wear.

Other options might seem plausible but do not provide an effective means of service. For instance, cleaning the oiling ring with a cloth does not address the contaminants present in the oil itself or in the sump. Simply replacing the entire bearing is an unnecessary and costly approach if the condition of the bearing is otherwise acceptable; maintenance should focus on cleaning and maintenance rather than replacement unless the bearing is severely worn. Adding fresh oil without draining does not remove the old, contaminated oil, which can continue to affect the bearing’s performance. Thus, the method of draining the sump is the most effective
