What characteristic do shaft sealing carbon glands possess?

• A. They are very brittle
• B. They are self-lubricating
• C. They require external lubrication
• D. They are prone to wear quickly

Answer: (B)

Shaft sealing carbon glands are specifically designed to function effectively in rotating machinery, primarily to prevent leakage of fluids from the shaft housing while allowing smooth rotation. The standout characteristic of these glands is that they are self-lubricating due to their material composition, which often includes graphite. This unique property allows them to maintain a low friction coefficient and reduce wear over time, enhancing reliability and lifespan. In applications where shaft sealing is critical, the self-lubricating feature of carbon glands mitigates the need for external lubrication, which can be messy or cumbersome, thereby simplifying maintenance. The design also promotes efficient operation under various temperature and pressure conditions, making them well-suited for dynamic applications in power engineering systems. This self-lubrication capability is crucial in ensuring the effectiveness of sealing without added complexities in lubrication management.
