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 |
