The material is with good wear resistance, low friction coefficient, corrosion resistance and high chemical resistance. It is suitable for the applications where the lubricating is hard to or not accessible. The machining requirement of the mating parts is not critical, so this kind of material is widely used in the general industry.
 

PTFE Sliding Bushing Tech. Data

PTFE composite flanged bushing maintenance-free steel backing

 
The PTFE-based sliding surface enables smooth running with low friction without lubrication. The presence or continuous supply of oil or other non-corrosive fluids can be beneficial and improve the performance of these bearings.
 
Advantages of PTFE composite plain bearings include:
● maintenance-free operation
● very good frictional properties
● high load carrying capacity
● operation temperatures up to 250°C
● sliding velocity up to 2 m/s
● small operating clearance
 
Applications include:
● automotive
● material handling equipment
● home appliances and consumer goods
● textile machinery
 

Typical Applications

PTFE composite bearings are resistant to oil, acids, and seawater. In addition, there is no lead in the PTFE surface layer and is particularly suitable for application in food machines, alkaline flow meters, pump handling elements in pharmaceutical machines, printing machines, chemical engineering machines, and other oceanic industries.
