Sliding Bushing, Stainless Steel Bushing , PTFE Self-Lubrication Multilayer Composite Bearings
Stainless steel backing bushing we also supply other kinds of oilless bushings. And sliding bearings in good quality!. Sf-1s/sf-1sw stainless steel self-lubricating bearing, du bushing, oil-less bearing, slide bearing. Sf-1s (sf-1sw, without lead pb) is special designed for corrodible environments. It is made of triple layer composites:. Stainless steel as base, porous bronze interlayer and ptfe surface layer. The products are widely used in machinery industry, such as the corrosion resistant part in dyeing machinery and ocean industry, etc. Features:. 1. Well self-lubricating. 2. Anti-wear and anti-corrosion. 3. Able to be used in strong acid corrodible environments. 4. Low vibration, low noise. Compact and light. 5. Working temperature range: -195. O. C~+280. O. C. 6.

Physical and Mechanical Performance
Normally, the surface polymer is chemical-erosion resistant quality. However it can be eroded by fused alkali metal and high temperature fluorine compounds. Stainless steel back is also chemical erosion preventive.
