Sliding Bearing Plate Washers: The Advantages of Teflon Coating in Thrust Bearings
Teflon-coated sliding bearing plate washers represent a blend of traditional engineering principles with modern material science. Their diverse benefits make them a sought-after choice in numerous industries. As technology progresses and the demands on machinery evolve, we can expect even more innovations in this space, with Teflon-coated components leading the way.
In the world of engineering and machinery, the devil often lies in the details. The efficiency, longevity, and functionality of a machine often depend on its smaller components. One such component that plays a pivotal role in various equipment is the sliding bearing plate washer, particularly those with Teflon coatings. This blog post aims to shed light on the benefits and applications of Teflon-coated thrust washers.
1. What is a Sliding Bearing Plate Washer?
Sliding bearing plate washers, commonly referred to as thrust washers, are designed to prevent movement along the axis of a shaft. They bear and distribute the axial loads, allowing for smooth rotation and movement of parts in machinery.
2. Enter Teflon: A Game-Changer in Coating
Teflon, the brand name for Polytetrafluoroethylene (PTFE), is a synthetic fluoropolymer known for its non-stick properties. When applied as a coating to thrust washers, it offers several advantages:
Low Friction Coefficient:
Teflon has one of the lowest friction coefficients among solid materials. This ensures that the washer allows parts to slide smoothly, reducing wear and tear.
High Wear Resistance:
The Teflon coating enhances the washer’s resistance to wear, extending its lifespan and reducing maintenance requirements.
Corrosion Resistance:
Teflon acts as a barrier against corrosive substances, ensuring the underlying material remains unaffected.
Temperature Tolerance:
Teflon-coated washers can operate efficiently under a wide temperature range without losing their integrity.
Self-lubricating Properties:
The non-stick nature of Teflon eliminates the frequent need for external lubrication, making the machine’s operation more seamless and less maintenance-intensive.
3. Applications of Teflon-Coated Thrust Washers:
Given their benefits, these washers find applications in:
- Automotive Industry: Used in transmissions, suspensions, and other components to ensure smooth movement.
- Aerospace: Where weight, reliability, and efficiency are paramount.
- Industrial Equipment: In machines where there’s a need for parts to slide or rotate smoothly.
- Home Appliances: Especially in devices with moving parts that require minimal maintenance.
4. Making the Right Choice:
While Teflon-coated thrust washers offer numerous advantages, they might not be the ideal choice for every application. It’s crucial to assess the operational conditions, load requirements, and environmental factors before making a decision.

PTFE is designed for complete dry friction and has developed a wide range of materials based on lubrication, friction coefficient and durability requirements. Bronzelube.com PTFE metal composite materials in the external lubrication or non-lubricating circumstances, can in the most extensive load, speed and temperature range to provide the best performance.
PTFE composite thrust washers are self-lubricating as well as maintenance-free and provide a long service life due to low friction. Despite their compact design, these washers can accommodate heavy axial loads and are suitable for relatively slow rotational or oscillating movements. They also have good dimensional stability and thermal conductivity.
PTFE composite washers consist of a sheet steel backing on which a 0,2 to 0,4 mm thick porous layer of tin/bronze is sintered. Furthermore, by a rolling process, the pores of the sintered layer are filled with a mixture of PTFE (polytetrafluoroethylene) and molybdenum disulfide additives. This additional 5 to 30 μm thick running-in layer provides an optimum combination of the mechanical properties of the sintered tin/bronze and the good sliding and lubricating properties of the PTFE mixture.
Running-in period
During a short running-in period, minute amounts of the PTFE material from the running-in layer are transferred to the counter surfaces. After this transfer has taken place, the characteristics of low friction and wear properties of these washers are reached.

Self-Lubricating Multilayer Composite Bushing is of excellent anti-abrasion performance, mainly due to the particular molecule structure of PTFE. The abrasion process can be generally divided into three phases, so there are kinds of friction coefficients. See the right graph:
1. “Running-in” phrase: PTFE compound on the bushing is transferred to its mating surface and forms a lubricating film. At this phase, the friction coefficient is bigger, thus the abrasion pace is very quick. See the curve shown in area I of the graph.
2. “Stabilization” abrasion phrase: After the “Running-in phase”, the friction happens between PTFE and PTFE, thus the friction coefficient is smaller and keeps steady. As a result, the wear rate is low and steady. See the curve shown in areaⅡof the graph.
3. “Sharp” abrasion phrase: As PTFE in the porous layer is slowly consumed up, not enough lubricant can be supplied to the gliding media. The friction coefficient and wear rate will rapidly rise. When 70% of the bronze surface is exposed, the service life of Self-Lubricating Multilayer Composite Bushing closes to its end. See the curve shown in area Ⅲof the graph.

Exploring PTFE Thrust Washers: The Harmony of Metric and Imperial Sizes
In the intricate dance of machinery, every component, no matter how small, plays a pivotal role in the overall performance. PTFE thrust washers, with their unique structure and design, are no exception. These components are available in both metric and imperial sizes, catering to a diverse array of applications. This article delves deep into the layered structure of the PTFE thrust washer and the inherent benefits each layer provides.
1. Versatility in Sizes and Shapes
- Metric and Imperial Sizes: To cater to global needs, PTFE thrust washers are available in both metric and imperial measurements. This ensures that engineers and technicians worldwide can find the right fit for their specific applications.
- Cylindrical Bushes: Perfect for applications where a direct, smooth, sliding surface is needed without any flange.
- Flanged Bushes: These are designed with a flange to support axial loads and prevent axial movement. Note: Flanged bushes are available in metric sizes only.
- Thrust Washer Bearings: Designed to support axial loads in low-thrust applications where radial space is limited.
- Flanged Washers: These provide a combination of radial and axial support. Available in metric sizes only.
- Strip Material: For those who need customization, strip material is available in metric sizes, allowing for custom shapes and sizes.
2. Delving into the PTFE Thrust Washer Structure
1. PTFE Mixture Layer:
The top layer consists of a PTFE mixture. After the washer undergoes a rolling process, this mixture fills the interstices of the bronze layer beneath it. During normal operation, some of this PTFE mixture is transferred to the mating surface, creating a physically lubricating film. This not only reduces the friction coefficient but also shields the mating shaft.
2. Porous Bronze Layer:
This layer is crucial as it bonds the PTFE layer to the steel backing. It provides the necessary strength and ensures that the self-lubricating properties of the PTFE layer are retained.
3. Steel Backing:
This layer is the backbone of the thrust washer. It provides the necessary support, ensuring that the washer can handle the loads it’s subjected to. Additionally, the steel backing offers excellent thermal conductivity, ensuring heat dissipation during operation.
4. Copper/Tin Layer:
Acting as a bridge between the steel backing and the porous bronze layer, this layer further enhances the washer’s strength and bonding capabilities
