Definition

Noun: A thrust bearing is a specialized type of bearing designed to support a load applied parallel to the axis of a rotating shaft. Its primary function is to manage axial loads (thrust) while allowing for rotational movement.

Usage

A thrust bearing is used in mechanical systems to handle force applied along the axis of rotation, preventing lateral movement of the shaft. - It is a critical component in applications like automotive transmissions, marine propellers, and turbines. - The design of a thrust bearing often involves washers or collars with rolling elements or fluid films to reduce friction.

Examples

Advanced Usage

• "to take the thrust": This describes the core function of the bearing.
  • The primary role of the thrust bearing is to take the thrust from the propeller shaft.

Variants and Related Words

• Bearing (n): A general machine element that constrains relative motion and reduces friction between moving parts.
• Axial bearing (n): Another term often used synonymously with thrust bearing, emphasizing its management of axial loads.
• Thrust washer (n): A simple type of thrust bearing, often a flat disk, used to handle lighter axial loads.

Synonyms

• Axial bearing
• Thrust plate (in specific, simpler designs)

Related Technical Phrases

• Thrust load (n): The axial force that a thrust bearing is designed to support.
  • Calculating the maximum thrust load is necessary for selecting the correct bearing.
