SF-2 Washer
SF-2 Washer
Say goodbye to the hassle of frequent lubrication maintenance. Our self-lubricating technology ensures smooth operation and reduces wear and tear, extending the lifespan of your equipment. Experience uninterrupted productivity and cost savings as you bid farewell to the need for messy lubricants and time-consuming upkeep.
POM (polyoxymethylene) lined washers, also known as self-lubricated washers, are a type of thrust washer that provides a low-friction, wear-resistant surface and is designed to operate without the need for additional lubrication. These washers are used in various applications to accommodate axial loads and reduce friction between moving parts.
Self-Lubricating SF-1WC
Carbon Steel self-lubricating bearings used high-quality low-carbon steel plate as base, sintered porous bronze as its interlayer, and the Compound of PTFE and Lead as its surface. It offers the property of good self-lubrication, low wear, low friction good sliding characteristics, low noise. It has been widely applied to various mechanical sliding positions, such as textile machinery, printing machinery, hydraulic pressure transit vehicle, tobacco machinery, gymnastic instrument, and agricultural machinery, etc.
POM lined washers are constructed from several distinct layers, each serving a specific function:
Steel Backing: This foundational layer ensures the washer’s structural stability and its capacity to bear loads.
Porous Bronze Layer: Attached to the steel through sintering, this layer secures the self-lubricating surface firmly in place and aids in heat distribution.
POM Sliding Layer: Positioned at the top, this polyoxymethylene layer includes lubrication pockets and may be enhanced with MoS2 (molybdenum disulfide) to improve resistance to wear and decrease friction.
During use, a portion of the POM layer is transferred to the contact surface, forming a lubricating film that diminishes friction and safeguards the counterpart shaft.
Advantages and Characteristics
Self-Lubricating: Designed to generate a continuous lubrication film, eliminating the need for additional lubricants.
Maintenance-Free: Ideal for scenarios where upkeep is challenging or not viable.
Cost Efficiency: Offers a compact solution that can reduce expenses owing to decreased maintenance demands.
High Resistance to Wear: The inclusion of MoS2 in the POM layer significantly enhances its durability and performance under low lubrication conditions.
Adaptable: Well-suited for various mechanical movements and capable of supporting substantial axial forces.
Use Cases
These washers find utility in diverse settings, such as:
Machinery for printing, textile manufacturing, and tobacco processing.
Equipment used in gymnastics.
Locations that are inaccessible for regular maintenance.
Environments prone to contamination where constant lubrication is impractical.
Choosing the Right Washer
To select an appropriate POM lined washer, consider the following:
Size and Load Handling: The washer should fit the specific application and be capable of supporting the anticipated loads.
Operating Conditions: Choose a washer that can withstand the particular environmental challenges, including temperature ranges and levels of contamination.
Maintenance Recommendations
Even though these washers are designed to be low-maintenance, regular inspections are advisable to monitor wear and ensure ongoing reliability and performance.
In conclusion, POM lined self-lubricating washers present a dependable and efficient means for minimizing friction and wear across various mechanical applications, with the added advantage of requiring minimal upkeep.

Materials
1. Modified polytetrafluoroethylene (PTFE) lead (Pb) mixture 0.01~0.03mm, a wear-resistant material, the operation process can form a transfer film to protect the grinding shaft.
2. Copper powder layer 0.2~0.3mm to improve the binding strength of PTFE/Pb and steel plate, with good bearing capacity and wear resistance. At the same time, copper is a good thermal conductivity material, which can quickly transfer the heat generated during the operation of bearings.
3. Low carbon steel 0.7~2.3mm, improve bearing capacity and heat transfer effect.
4. Copper/tin electroplating, copper plating 0.008mm, tin plating 0.005mm, so that the bearing has a good corrosion resistance.
High-quality Thrust Washer
Sf-2 Thrust Washer Plain Bearings
The SF-2 thrust washer material is a PTFE-modified surface layer filled with POM plastic of the three-level self-lubricating composite material, which is a benign boundary lubricating material, and therefore particularly suitable for low-speed and loaded rotational movement. high, rocking motion and frequently open and close under load and difficult to form hydrodynamic lubrication of bearings, thrust washer only, slider, tees, and other friction parts. The SF-2 can fully utilize the grease trace lubrication under boundary lubrication conditions without refueling for long-term maintenance.
High-quality low carbon steel as the matrix
The Thrust Washer Plain Bearing is made of high-quality low carbon steel and sintered spherical porous bronze powder in the middle, which is firmly integrated with surface modified POM. Surface rolling oil storage pit to achieve good lubrication between friction surfaces. It has good wear resistance and bearing capacity, steel back surface coating corrosion resistance, widely used in automobile chassis, forging machine tools, mining machinery metallurgy machinery, water conservancy and steel rolling industry.
