Efalon® (PTFE) sliding
bearings, supports and guides are used in bridges, buildings, roofs,
tunnels, pipe lines, heavy industry constructions, steel constructions
and storage tank supports to eliminate and absorb expansions and
contractions, vibrations, effects of earthquakes and changes in load.
PTFE sliding bearings are produced vested in steel, adhering to steel
or mechanically adhering to steel. Bearings that are vested in steel are
preferred in very high load applications. In bearings that adhere to
steel, the bond between steel and PTFE is very strong as a result
of the special application method whereas assembly of bearings mechanically adhering to steel is short and simple.
Polikim ofers many types of sliding guides on request and also skived
tapes, etched one side commonly used in
sliding guides.
High fatigue resistance, long
operating life without any need for lubrication and
maintenance
Applied easily to all types of motions
Virgin Efalon®
(PTFE) is the first choice for sliding bearings whereas compounded Efalon® (PTFE) materials are
used in critical applications such as high sliding
velocity and heavy loads.
Uniform load
on Efalon® (PTFE) sliding guides is 280kg/cm²
depending on type of material, bearing and design.
In cases where bearing
material is compounded Efalon® (PTFE), bearing is produced vested in metal and in special
designs, this value can be increased up to 500kg/cm².
Various tests
and experiments point out that optimum bearing thickness is 2.5mm,
but in critical applications and depending on
type of bearing, thickness can be different.
PTFE sliding
bearings generally do not require lubrication, but in some special applications we recommend lubrication with silicone
grease during assembly in order to decrease friction. Except for
this special treatment at the beginning, PTFE sliding guides do not require maintenance and
lubrication.
