How is a dental-type coupling lubricated?

A dental-type coupling is lubricated by a continuous flow of oil through an adjacent bearing feedline. This design ensures that the coupling receives a consistent supply of lubrication, which is essential for reducing friction and wear during operation. The continuous oil flow helps to maintain a stable temperature, prevents contamination, and keeps the lubrication system functioning effectively.

In this context, the coupling’s reliance on an external lubrication source reflects the need for reliability and minimal maintenance in marine and industrial applications. By constantly supplying oil, the coupling can perform efficiently and withstand the demands of its mechanical environment, making it a preferred choice in many systems.
