Thrust washer

What is a thrust washer?

A thrust washer is a mechanical component used to support high axial loads while reducing friction. It acts as a contact surface between moving parts, distributing loads and minimizing wear. These washers are essential in mechanical assemblies and thrust bearings where axial forces are significant, particularly in thrust ball bearing assemblies, where they serve as a contact surface or ball raceway.

Different thrust washer profiles

Thrust washers are available in several profiles to meet specific needs:

• Flat thrust washers: These are the most common type, offering a wide contact surface for uniform load distribution.

• Needle thrust washers: These feature cylindrical needles to support high axial loads with low friction. Ideal for applications requiring high load capacity and low wear.

• Roller thrust washers: Consisting of cylindrical rollers, these washers distribute loads evenly and offer high durability, suitable for demanding industrial environments. These washers are often used to complement bearings supporting radial loads.

Special features of thrust washers

Thrust washers offer several key advantages that make them indispensable in a variety of applications:

• Axial load support: They are designed to support high axial loads, protecting adjacent components and ensuring the stability of assemblies.

• Reduced friction: By minimizing friction between contacting surfaces, they extend component life and improve the efficiency of mechanical systems.

• Durability: Made from high-quality materials such as hardened steel or stainless steel, these washers resist wear, impact and corrosive environments.

• Versatility: Available in several sizes and configurations, they can be used in a wide range of industrial and mechanical applications, including single-acting and double-acting thrust bearings.

How to choose the right part number?

To select the thrust washer best suited to your needs, several criteria need to be taken into account:

• Specific application: Identify the specific requirements of your application, such as axial load, rotational speed, and environmental conditions (humidity, temperature, chemical exposure).

• Washer type: Choose the type of washer (flat, needle or roller) according to the loads and performance required. Needle and roller washers are preferred for high loads and industrial environments.

• Dimensions : Make sure that the dimensions (outside diameter, inside diameter, thickness) perfectly match your application to ensure correct installation and optimum performance.

• Materials: Select washers made from materials suitable for the environment in which they will be used. Corrosion-resistant materials, such as stainless steel, are recommended for damp environments or those exposed to chemicals.

Advantages of thrust washers for various industrial applications

• Automotive: Used in transmissions and steering systems to support axial loads and reduce friction, improving vehicle durability and performance.

• Heavy machinery: Essential in construction and materials handling equipment, where heavy loads and harsh conditions are commonplace.

• household appliances: Built into household appliances to keep moving components running smoothly by reducing wear and friction.

• Aerospace: Used in control systems and aircraft engines for their ability to withstand high axial loads and operate in extreme conditions.
