Swing pad®

It is the sliding material with PTFE as the basic material.
It has an excellent self-lubrication and low-friction property and provide superior performance especially under low speed and high-load conditions.
Also, it withstands severe temperature change, absorbs the effect of dead load and live load of earthquake by the smooth sliding, and prevents the dangerous stress from occurring.

Use

●Industrial use: Plant related/Pipelines/Storage tanks/Boilers/Flood gates/Others
●Construction use: Beam support/Curtain walls/Transit corridor expansion/Gate slides/Others
●Public works: Highway bridge support/Railway bridge support/Others
●Others: Vehicles (Central plate slider and lateral plate slider of the truck)/Bearings material for extruded construction/Vessel movable carriage/Others

Characteristics

●Low coefficient of friction: A very low coefficient of friction can be obtained under low speed and high-load conditions.
●Smooth sliding characteristics: There is no phenomenon such as self-welding and stick-slip, the deformation such as expansion or shrinkage at the time of heavy load is smoothly absorbed.
●Complete self-lubrication: It is a complete oil-free sliding material which does not require maintenance such as lubrication.
●Simple design: Good workability, and since the thin plate is placed on the sliding surface, it is available in simple and compact design.
●Excellent weather resistance: It is hardly affected by the weather or climate even if exposed outdoors. Also, there is no rusting or corrosion, and the friction coefficient remains stable in the wide range of temperature.
