Thrust Washer Bearings

Thrust washer bearings are flat, disc-shaped bearings typically positioned between a rotating component and a stationary one. They function by keeping the rotating component in its proper axial position, providing a durable surface for the component to rub against if it attempts to move laterally or axially.

Unlike traditional metal washers that often require external lubrication and can corrode in harsh environments, iglide® thrust washers are made from high-performance plastic materials. They are self-lubricating, promote maintenance-free dry operation, and are resistant to corrosion, which helps prevent unplanned downtime.

Dry washers (usually composite or polymer-based) are self-lubricating and don't require external grease. Lubricated washers (steel or bronze) require a constant film of oil or grease to operate without welding themselves to the shaft.

The most frequent culprits are:

• Misalignment: If the shaft isn't perfectly perpendicular to the washer, it creates uneven wear.
• Starvation: Lack of lubrication leads to rapid heat buildup and seizing.
• Contamination: Abrasive particles getting trapped between the washer and the rotating face

Generally, no. Stacking washers creates multiple friction interfaces. Unless they are pinned or keyed together, one washer might spin against another, doubling the heat generation and potentially causing a "clutch" effect that disrupts your torque calculations. It is always better to source a single washer of the correct thickness

Because of their durability and maintenance-free nature, these bearings are commonly used in the following industries:

• Agriculture
• Automotive
• Construction machinery
• Fitness equipment
