Product Overview:Apply to the oil or fuel work harder parts,wear resistance.low coefficient of friction,long life;good overall performance.Apply to the oil or fuel work harder parts,wear resisrance.low coefficient od friction,long life;good ocverall performance.
PTFE lined selflubricating bearing also called DU bushing, dry bushing, DU bearing,teflon bushing,
PTFE coated bearing,SF1 oilless bearing and PTFE based plain bearing.
This type of DU bush takes PTFE layer as sliding layer which makes products
can perform very well under dry condition or oil condition.
Steel back self lubricating bearing
Plain steel bushing is a type of DU bushing. It's also called teflon bearing,DU bush and
PTFE lined dry sliding bearing,SF-1 bearing,oil free bushes.self-lubricating
bearing has a common structure with other DU bearing.
Material structure:
PTFE/Pb mixture 0.01~0.03mm as sliding layer, provides an excellent initial transfer film,
which effectively coats the mating surface of the bearing assembly,
forming homogeneous oxide type solid lubricant film.
Porous bronze 0.2~0.3mm, provides Max. thermal conductivity away from the bearing surface,
also serves as a reservoir for the PTFE-lead mixture.
Low-carbon steel backing 0.7~2.3mm, provides fundamental structural support and
gives exceptionally high load carrying capacity, excellent heat dissipation.
Tin-plating 0.005mm or copper plating 0.008mm, provides good corrosion resistance.
Characteristics:
Good wear and friction performance over a wide range of loads, speeds and temperature without oil
Also perform well with lubrication
Maintenance-free, long life
Availability:
Standard cylindrical bushing, flanged bush, thrust washers and strips are available.
Lead free type is also available
All special designs are produced according to your requirement
Applications:
DU bearing is widely used in Lifting equipment, Hydraulics and valves,
pneumatic equipment, medical equipment, textile machinery, agricultural equipment,
construction equipment, meterial handing equipment,
packaging equipment, automotive field, scientific equipment, drying ovens, office equipment, etc.
