Thrust Washer Bearings: Axial load management made simple.

Thrust washer bearings by Viiplus

Thrust washers can be found in almost every appliance, machine, transportation conveyance, power tool, and recreational device that has moving parts, axles, bolts, pins, bearings, and rotating components. In their simplest form, thrust washers are long-wearing flat bearings in the shape of a washer that transmit and resolve axial forces in rotating mechanisms to keep components aligned along a shaft. Thrust washers are an economical alternative to rolling thrust bearings whenever forces velocities are moderate.

Thrust washer bearings work by reducing friction between two surfaces that move against each other. When axial loads are applied, the rolling elements in the bearing move between the raceways on the shaft and housing washers, distributing the load evenly and reducing friction. This allows the two washers to move smoothly against each other without wearing out.

Axial Load Thrust Washer

What is a Thrust Washer Bearing?

Thrust washer bearings are flat bearings that are typically inserted between a rotating component and a stationary component, and function to keep the rotating component in place by providing it with something to rub up against if it begins to move laterally. They support the axial load or side-to-side motion on a shaft. Viiplus thrust washer bearings are made from self-lubricating materials that promote maintenance-free, dry operation for a wide range of applications and axial load requirements.

Thrust washer bearings offer several advantages, including:

  • High load-carrying capacity: Thrust washer bearings can support high axial loads and are suitable for heavy-duty applications.
  • Low friction: The rolling elements in the bearing reduce friction, resulting in smoother operation and less wear on the bearing.
  • High precision: Thrust washer bearings can provide precise axial positioning and are often used in applications where accuracy is crucial.

Types of Thrust Washer Bearings

There are several types of thrust washer bearings, each with its unique design and application. Let’s take a look at the most common ones:

  1. Plain thrust washer bearings, also known as flat washers, are simple, flat, and round components with a hole in the center. They are made from materials like bronze, steel, or plastic, and are used in low-speed applications with minimal axial loads.
  2. Ball thrust bearings consist of two grooved washers and a set of balls held together by a cage. These bearings are capable of handling moderate axial loads at high speeds, making them suitable for applications like pumps, compressors, and machine tool spindles.
  3. Cylindrical roller thrust bearings use cylindrical rollers instead of balls, offering higher load-carrying capacity and better rigidity.
  4. Tapered roller thrust bearings use tapered rollers arranged between two angled raceways, providing the ability to handle combined axial and radial loads.
