A shaft sleeve is a protective component used to shield rotating shafts from wear, corrosion, and debris in boiler and burner systems. Typically made from durable metals or engineered plastics, this sleeve fits over the shaft to reduce friction and extend the life of connected parts like fans or pumps. When servicing heating equipment, replacing a worn shaft sleeve can prevent misalignment and vibration, ensuring smooth operation. This small but crucial part is often overlooked during maintenance but plays a key role in system reliability.
