friction-ball

A mechanic replaces a worn friction-ball in a machine's joint.

Definition

1. Noun:
   • Technical term: "friction-ball" refers to a ball used in machinery to reduce friction, typically found in bearing assemblies or devices where moving parts require smooth rotation. It is a component that minimizes resistance between surfaces in contact.

Usage Examples

• Noun:
  • The engineer replaced the worn friction-ball in the bearing to ensure smooth operation. (A ball that reduces friction in a mechanical component.)
  • A high-quality friction-ball can significantly extend the lifespan of a rotating shaft. (A ball used to decrease wear in machinery.)

Advanced Usage

• "friction-ball bearing": a type of bearing that uses friction-balls to facilitate movement.
  • The bicycle wheel relies on friction-ball bearings for efficient pedaling. (Bearings that incorporate friction-balls to reduce resistance.)

Variants and Related Words

• Friction (n): the resistance that one surface or object encounters when moving over another.

  • The friction between the tires and the road provides traction. (The force that opposes motion.)

• Ball bearing (n): a bearing using small balls to reduce friction between moving parts.

  • A ball bearing is commonly used in skateboard wheels. (A bearing that employs balls for smooth rotation.)

Synonyms

• Antifriction ball: a ball designed to reduce friction.
• Bearing ball: a spherical component used in bearings.

Phrasal Verbs

• None directly applicable to "friction-ball" as a noun; however, the related verb phrase "to reduce friction (with a friction-ball)" can be used.
  • The mechanic reduced friction by installing a new friction-ball. (Decreased resistance using the component.)
