The use of the ring or chain method for oiling the bearings of auxiliary generators in marine service is widely recognized due to its effective distribution of lubrication. This method involves utilizing a continuous loop of an oil ring or chain that moves through an oil reservoir. As the ring or chain rotates, it scoops up the oil and carries it to the bearings, ensuring that an adequate supply of lubricant is consistently provided.

This approach is particularly suitable for marine applications where reliability and maintenance are critical, as it reduces the risk of bearing failure due to inadequate lubrication. The design allows for a controlled and steady flow of oil, minimizing friction and wear on the bearings, which are essential for the long-term operation of the generators. This reliable method caters well to the dynamic conditions encountered at sea, where generators must operate under varying loads and environmental factors.

Other methods of lubrication, while potentially effective in different contexts, may not provide the same level of reliability or efficiency for marine service applications. The ring or chain method stands out for its ability to handle continuous operation, which is vital for auxiliary generators running in marine environments.
