Dry sliding thrust washers with metric dimensions of triple-layer PTFE composite thrust washer material

Bushing, flange bushing, Scheiben,composite material.Good wear resistance and lubricity.It has very good performance in the application of oil lubrication.SCHEIBEN,Gleitlager, Anlaufscheiben und Bandstreifen,PTFE Composite Gleitlager Anlaufscheiben ,PTFE composite thrust washer is suitable for applications requiring self-lubricating sliding materials.Examples of applications for these discs are:

1. Automotive engineering
2. Material handling
3. Household appliances and consumer goods
4. Textile machinery

Material organization
1. Modified polytetrafluoroethylene (PTFE) lead (Pb) mixture 0.01~0.03mm, a wear-resistant material that can form transfer film to protect the grinding shaft during operation.
2. Copper powder layer 0.2mm ~0.3mm improves the bonding strength of PTFE/Pb with steel plate, with good bearing capacity and wear resistance.At the same time copper is a good thermal material, can quickly transfer the heat generated in the process of bearing operation.
3. Low carbon steel 0.7-2.3mm, improve bearing capacity and heat transfer.
4. Copper/tin plating, copper plating 0.008mm, tin plating 0.005mm, so that the bearing has a good corrosion resistance.
Main parameters:
Static load of 250 n/was
Friction coefficient 0.03~0.20
Dry friction 2 m/s
Lubrication 5m/s
PV value (dry friction) intermittent operation 3.6n /mm2.m/s
Thermal conductivity 42W(m.K)-1
Long-term operation 1.8n /mm2.m/s
Linear expansion coefficient 11x11-6k
Operating temperature: -195℃~+280℃
Application features:
1. No oil lubrication or less oil lubrication, suitable for the occasion where oil cannot be filled or difficult to be filled, can be used without maintenance or less maintenance;
2. Good wear resistance, small friction coefficient and long service life;3. Can be used in the range of -195℃ ~ +280℃;
4. Good running performance, low noise, no pollution;5. Thin-walled structure, light weight, can reduce the mechanical volume;
6. The transfer film can be formed during operation to protect the grinding shaft, without biting the shaft;
7. The hardness requirement of the grinding shaft is low, and the shaft without the tempering treatment can be used, thus reducing the processing difficulty of relevant parts;
8. No water absorption and oil absorption, low coefficient of thermal expansion, good heat dissipation and stable size;
9. The back of the steel can be plated with a variety of metals, so it can be used in corrosive media without rust;
At present has been widely applied to various mechanical sliding parts, such as automatic mechanical equipment (telescopic, swing, slide, bending, cyclotron, turning parts) hydraulic cylinder guide sleeve, gear pump pu, textile machinery, vending machines, plastic molding machine, die-casting machine, rubber machine, tobacco machine, fitness equipment, office machinery, hydraulic truck, automobile, motorcycle, forestry machinery, etc.
