Introduction:
Bearings are needed to transfer the vertical forces from one
structural member to another. They are also required to
restrict or permit linear or rotational movement. Where
hofizontal movement is restlicted..the horizontal forces will be
transferred through bearing to the lower structure.
Application:
SNEHA make PTFE/SS Bearinghave wide applicationsin the field of,
1.
Bridges : PlateGirder,Truss, Arch, Suspension,Cable Stayed, lviovable.
2.
Structural : Building,Spods Complex,Auditoriums,Pipe Supports,Vessel
Supports,Gantry Supports.
3.
Pollution Control r Precipitators,
Bag Houses,Valves,Ducts.
4.
Off Shore : Platforms,Turn Tables,Crane Pivot.
5.
Oil & Chemical Refinery Equipments : Heat Exchangers,Pipe Lines, Hanger

Proprties of PTFE :
The wonder materialPTFE
possessesfollowing
(Polltetrafluoroethylene)
properties:
1. Chemicallyinert.
2. Low coeflicientof fridion.
3. High wear resistance.
4. Immune to almost all known solvents,
5. Can operate over wide range of temperature.
Friction:
The exact value of coefficientof frictioncan not be quoted since it depends on
many factorssome of the major governingfactorsare,
unit Loading
Sudace finishof mating pats
l. Temperature
l Speed of movement
Periodunder joad without movement.
The dynamic coelficientof frictioncan be as low as 0.005 but for design
considerations
the coefficientof frictionis taken as 0.05.
Advantages of PTFE / SS Bearings:
1. Low Coefficientof Frlction.
2. No maintenancerequired.
3. No lubrlcation
required.
4. Life Long
5. High oad caringcapacity.
6. CoTpact i_ size.
Te s t i n g :
1. Sample bearingsare tested for 1.25 times design load capacib/.
2. A pair of bearing selectedat random is tested for coefficientof friction,
3. Sample bearingsare also teste for peimissiblerotation.
All the tests are carriedout on finishedproductsin house on sophisticated
test rig.
