Definition

1. Noun:
   • A cylindrical metal lining used to reduce friction: A "cylindrical lining" is a hollow, tube-shaped component, typically made of metal, that is inserted into a housing or bore. Its primary function is to provide a smooth, wear-resistant surface that minimizes friction between moving parts, such as a piston and a cylinder wall.

Usage Examples

• Noun:
  • The mechanic replaced the worn cylindrical lining in the engine block.
  • A high-quality cylindrical lining is essential for the efficient operation of hydraulic pumps.

Advanced Usage

• Technical Context: In engineering, a "cylindrical lining" often refers specifically to a or installed in a cylindrical bore to support a rotating shaft or sliding component, thereby reducing wear and friction.
  • The design specifies a bronze cylindrical lining for the connecting rod's big end.

Variants and Related Words

• Bushing (n): A type of cylindrical lining, often a removable sleeve, used as a bearing or guide.
• Sleeve (n): A tube that fits over another part, often serving as a lining, bearing, or guide.
• Liner (n): A general term for a lining; a "cylinder liner" is a specific type of cylindrical lining in an engine cylinder.

Synonyms

• Bushing
• Sleeve bearing
• Cylinder liner (in specific contexts like internal combustion engines)

Related Phrases
