SF-1S ( lead free ) Dry ( maintenance free ) , Stainless Steel Bushing
Stainless steel bearing is a type of lead free DU bushing. This type plain sliding bearing has common structure with other DU bearings. It's also called PTFE bush, PTFE bearing, lead free self-lubricating bearing, dry bushing, SF-1oiless bearing and plain sliding bearing.
Material Structure:
1. PTFE with Oil fibre 0.01~0.03mm as sliding layer
2. Porous bronze 0.2~0.3mm 3.Stainless steel backing 0.7~2.3mm
Characteristics:
This type plain sliding bearing have all the properties of TOB012 self-lubricating bushing.
Without lead which makes the bushing lubricating condition more cleanly.
Without lead which makes the bushing accord with environmental protection request
Applications:
Stainless steel bushing is widely used in strong acid and alkali situation, such as chemical industry, pumps, and valves.
Lead free bearing is widely used in food machine, pharmaceutical machine
