Introduction:Bearings are needed to transfer the vertical forces from onestructural member to another. They are also required torestrict or permit linear or rotational movement. Wherehofizontal movement is restlicted.. the horizontal forces will betransferred through bearing to the lower structure.

Application :SNEHA make PTFE/SS Bearing have wide applications in the field of,1. Bridges : Plate Girder, 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, HangerBearings.

Proprties of PTFE :The wonder material PTFE(Polltetrafluoroethylene) possesses followingproperties :

1. Chemically inert.

2. Low coeflicient of fridion.

3. High wear resistance.

4. Immune to almost all known solvents,

5. Can operate over wide range of temperature.

Frict ion:The exact value of coefficient of friction can not be quoted since it depends onmany factors some of the major governing factors are, unit Loading Sudace finish of mating patsl. Temperaturel Speed of movement Period under joad without movement.The dynamic coelficient of friction can be as low as 0.005 but for designconsiderations the coefficient of friction is taken as 0.05.

Advantages of PTFE / SS Bearings:1. Low Coefficient of Frlction.2. No maintenance required.3. No lubrlcation required.4. Life Long5. High oad caring capacity.6. CoTpact i_ size.

Test ing:1. Sample bearings are tested for 1.25 times design load capacib/.2. A pair of bearing selected at random is tested for coefficient of friction,3. Sample bearings are also teste for peimissible rotation.All the tests are carried out on finished products in house on sophisticated test rig.
