Kastaş K780 bushings used high quality low-carbon steel plate as base , sintered porous bronze as its interlayer and the compound of PTFE as its surface. It offers the property of good self-lubricaiton , low wear , low friction , good sliding characteristics , low noise.


PRODUCT ADVANTAGES
• Working under oilless or minim oil state condition
• Abrasion Resistance
• Low fricton coefficient and long service life
• Good thermal conductivity and size stability
• Forms a transferred film during operation to protect shaft
• High load resistance
 
MATERIAL STRUCTURE
PTFE with mixture
Porous bronze
Steel backing
