Product Description
Stainless Steel Oil-Free Bushing with Self-Lubricating Properties
JS-1S oil-free bushings feature a stainless steel backing (AISI 304, 316, or 316L) with sintered porous bronze layer infused with PTFE and reinforcing fibers. These self-lubricating components deliver exceptional performance in demanding environments without requiring external lubrication.
Key Features
• Excellent corrosion resistance against acids, alkalis, and seawater
• Self-lubricating design eliminates need for oil or grease
• Pb-free composition for environmental compliance
• Superior wear resistance with friction coefficient of 0.02-0.20
• Wide operating temperature range from -195℃ to +280℃
