SF-1 Washer
Self-Lubricating SF-1WC, SF-1 Washer
Carbon Steel self-lubricating bearings use high-quality low-carbon steel plate as the 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, and low noise. It has been widely applied to various mechanical sliding positions, such as textile machinery, printing machinery, hydraulic pressure transit vehicles, tobacco machinery, gymnastic instruments, and agricultural machinery, etc.
Proven, long-lasting composite washer, self-lubricating metal-polymer bushings and thrust bearings, heavy-duty thrust washer bearings, SF-1 Washer
SF-1 washers, also known as self-lubricating dry washers, are components designed for applications where maintenance-free operation and reduced friction are essential. These washers typically consist of a steel base with a layer of porous bronze particles in the middle and a surface layer of PTFE (polytetrafluoroethylene) for self-lubrication. The PTFE layer provides low friction, wear resistance, and noise reduction properties.
The structure of SF-1 washers includes:
- Self-lubricating layer: A thin layer (0.01-0.03mm) of PTFE and fibers that form a transfer film during operation to reduce friction and protect mating surfaces.
- Bronze powder layer: Acts as an intermediary between the self-lubricating layer and the steel base.
- Low carbon steel layer: Provides structural support and heat dissipation during operation.
- Copper/tin coating: Offers corrosion resistance to the washer.
SF-1 washers are widely used in various machinery applications such as printing presses, textile machines, automotive components, agricultural machinery, and more due to their self-lubricating properties, wear resistance, low friction coefficient, and ability to operate without oil lubrication. These washers contribute to cost reduction, machine size optimization, noise reduction, and prevention of shaft wear issues.

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.
