A Sleeve is used to provide a lining for a hole or a bearing surface. It's designed to reduce friction and wear between two moving parts. Sleeves provide a replaceable wear surface, which can extend the life of the parts they are used with. They can be replaced when they wear out, rather than replacing the entire part. They are typically made of steel.Attributes:• Provide abrasion resistance and protection from damage, wear, and tear for enclosed part• Withstands a range of temperatures and can handle the effects of thermal expansion and contraction• Manufactured to precise specifications and are built for durability and reliabilityApplications:A Sleeve is often used to connect rods, bolts, screws, and other cylindrical parts.
