The Plain Bearing Steel Sintered Bronze with PTFE Layer Thrust Washer for wind turbine parts is a specialized component designed to handle axial loads in demanding environments. Here’s a detailed breakdown:
Structure & Composition
-
Steel Backing: Provides structural strength and durability, ensuring the washer can withstand high axial loads and mechanical stresses.
-
Sintered Bronze Layer:
-
Created via powder metallurgy, this porous layer retains lubricants (e.g., oil) for self-lubrication, reducing maintenance needs.
-
Enhances load distribution and thermal conductivity.
-
-
PTFE Top Layer:
-
Offers ultra-low friction, reducing wear and energy loss.
-
Provides chemical resistance and dry lubrication, ideal for harsh or corrosive environments.
-
Key Features
-
Low Maintenance: Combines sintered bronze’s oil retention with PTFE’s dry lubrication, minimizing the need for re-lubrication.
-
High Load Capacity: Steel backing supports heavy axial loads common in wind turbine applications.
-
Durability: Resists wear, corrosion, and variable operational stresses (temperature, moisture, contaminants).
Applications in Wind Turbines
-
Gearboxes: Manages axial loads between rotating components.
-
Yaw Systems: Supports smooth rotation under wind direction changes.
-
Main Shaft/Pitch Control Systems: Ensures reliability in high-stress, low-maintenance environments.
Design Considerations
-
Temperature Limits: PTFE operates optimally below ~260°C, suitable for most turbine applications.
-
Material Bonding: Robust adhesion between layers is critical to prevent delamination under cyclic loads.
-
Load Distribution: Even pressure across the PTFE layer avoids localized wear.
Manufacturing & Testing
-
Process: Sintering bronze onto steel, followed by PTFE coating (spraying/pressing) and curing.
-
Validation: Accelerated life testing under simulated conditions (load cycles, temperature, moisture) ensures performance and longevity.
Benefits for Wind Turbines
-
Reliability: Reduces downtime in hard-to-access turbine components.
-
Efficiency: Low friction improves energy output.
-
Longevity: Withstands harsh outdoor conditions, extending service intervals.
Challenges Addressed
-
Corrosion Resistance: PTFE and bronze protect against moisture and chemicals.
-
Thermal Management: Sintered bronze dissipates heat, while steel prevents deformation.
This thrust washer exemplifies a multi-material solution tailored for wind energy’s rigorous demands, balancing strength, lubrication, and environmental resilience.

Sf-1wc oil-free bearings are made of steel plate with sintered spherical bronze powder in the middle and rolled PTFE and mixture on the surface. It has the characteristics of low friction coefficient, wear resistance, good corrosion resistance and no oil lubrication. It can reduce the cost, reduce the size of the machine, avoid the phenomenon of shaft biting and reduce the noise and other advantages. Products have been widely used in various machinery sliding parts, such as: printing press, textile machine, tobacco machinery, automobile, motorcycle and agricultural and forestry machinery….
It is generally recommended that the tolerance of seat hole is H7 and the tolerance of shaft diameter is H8
Features
Suitable for dry running with a low coefficient of friction, low wear rate, good sliding characteristics, the transfer film created will protect the mating metal surface. Suitable for rotary and oscillating movement, high chemical resistance, lower absorption of water and reduced swelling. Also performs well with lubrication.

Typical Applications
Wind turbine bushing & thrust washer
A wind turbine is a device that converts kinetic energy from the wind into electrical power. A wind turbine used for charging batteries may be referred to as a wind charger. The result of over a millennium of windmill development and modern engineering, today’s wind turbines are manufactured in a wide range of vertical and horizontal axis types. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs. Slightly larger turbines can be used for making contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Arrays of large turbines, known as wind farms, are becoming an increasingly important source of renewable energy and are used by many countries as part of a strategy to reduce their reliance on fossil fuels.
