Stainless steel bearing's material structure: 1. PTFE with Pb 0.01~0.03mm 2. Porous bronze 0.2~0.3mm 3. Stainless steel backing 0.7~2.3mm Characteristics of stainless steel self-lubricating bearing: Low friction coefficient, good anti-wear, good anti-corrosion Performs well in mid-acid and strong alkaline condition Availability: Standard cylindrical bushings, flanged bushings, thrust washers and strips are availabe Special designs are produced at short notice Lead free type is also available Applications of stainless steel bushing: Dyeing machine, ocean industry, chemical industry, valves etc
SF012,SF017 Stainless Steel Self-lubricating bearing
It is based on stainless steel plate with sintering porous bronze layer and it's surface is coated the compound of PTFE and PB.It can be used in strong acid and alkaline,It's applied to the corrosion resistant part in dyeing mathmery and ocean industry,etc.
Note:SF017 without lead
Cylindrical bushes,flanged bushes,thrust wahsers,strip and non-standard parts as the clients supplied drawing and etc.
Recommended housing bore tolerance is H7,while the shaft diameter tolerance is F7 or H8.
