We offer a comprehensive range of PAP bushes, PTFE composite bronze Gleitlager (plain bearings), Anlaufscheiben (run-in rings), thrust washers, and strips that are designed to meet the diverse requirements of various industrial applications.
Our PAP bushes are made from high-performance materials that provide excellent wear resistance, low friction, and long service life. They are suitable for use in demanding environments and are often used in automotive, aerospace, and heavy machinery applications.
The PTFE composite bronze Gleitlager (plain bearings) we offer are a combination of bronze and PTFE (polytetrafluoroethylene), resulting in a material that offers superior mechanical properties and wear resistance. These bearings are ideal for high-speed and high-load applications, providing smooth and reliable operation.
Anlaufscheiben (run-in rings) are designed to facilitate the initial running-in process of bearings and bushings. They help reduce wear and friction during the initial startup phase, extending the overall service life of the bearings.
Our thrust washers are precision-engineered components that are used to support and transmit thrust loads. They are made from high-strength materials that can withstand extreme pressures and temperatures, ensuring reliable performance in demanding applications.
Lastly, we offer a range of strips that are cut from our high-quality materials to specific dimensions. These strips can be used in various applications, including gaskets, seals, and wear-resistant surfaces.
By choosing our PAP bushes, PTFE composite bronze Gleitlager, Anlaufscheiben, thrust washers, and strips, you can expect superior performance, durability, and reliability. We are committed to providing our customers with the best products and services, ensuring that your industrial operations run smoothly and efficiently.
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:
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.
PTFE composite thrust washer is suitable for space-saving axial guide bushing bearings for high load/medium speed applications.VIIPLUS offers a variety of PTFE composite thrust washers.The advantages of these slots are:
