PROPERTIES
Guided bearing for high temperatures, as compact
flat sliding bearing, with high load PTFE-coated
sliding plate, maintenance-free.
MOUNTING
To weld on, as a special design also available as a
screw-on application.
MATERIAL
Steel, St52-3 (1.0570) (SJ355J2G3)
CORROSION PROTECTION
Galvanic zinc-plated (8 - 12 µ), or corrosion protection
coating.
BASE PLATE
One sided embedding for sliding plate.
The lower side is furnished with a 3x45° welding
bevel, which simplifies the welding to the lower
construction layer. Additional centred drills or
threads serve as a mounting assistance.
SLIDING PLATE
Bronze plate with high stress load PTFE-sliding
layer embedded in bearing support.
Friction value: approximately 0,05 - 0,10, on a
stainless steel sliding plate‚ Verf. 2R (IIId).
LOwER TOP PLATE
Steel plate with cleat guide and welded on stainless
steel sliding plate, Verf. 2R (IIId), with protection
film.
Additional centred drills or threads serve as a
mounting assistance.
UPPER TOP PLATE
Steel plate with cleat surrounding for embedding
of the heat isolation plate.
Additional centred drills or threads serve as a form
of mounting assistance.
HEAT ISOLATION PLATE
High pressure-resistant and insulating material,
which prevents overheating of the PTFE-sliding
layer and therefore enables temperature ranges of
up to +500°C.
SLIDING DIRECTION
A guided bearing - one-sided
GLIDE PATH
See chart
CHARACTERISTICS
Suitable for high temperature ranges, ≤ 500°C
Suitable to absorb high siding loads.
Very compact construction, small
measurements (see chart)
Maintenance-free with great durability due to
the PTFE – sliding layer.
High capacity load (stat. approx. 250 N/mm²),
for comparison: solid PTFE - sliding plate
approx. 10 N/mm².
Very compact construction, small
measurements (see chart)
Corrosion resistant
Low friction coefficient, no »stick-slip« effect.
Optimal operational safety

The base plate must be welded to the collaborating
lower construction of the respective
LHG - supporting bearing.
If required the zinc-coating must be removed
from the designated welding bevels to enable
clean welding.
To reconstruct the broad corrosion protection
all welded joints must be provided with antirust
coating, zinc spray or similar.
During welding the carrying area for the PTFEsliding
plate must be covered!
The top plate (and respectively the upper top
plate of the high temperature bearings) must
be welded to the upper construction with consideration
taken of the sliding direction.
The glide path of LHG - standard supporting
bearing is already designated by the size of the
top plate with the stainless steel sliding plate.
The exact glide path can be seen in the documents.
Despite the existing protection film on the
stainless steel sheet, this area has to be additionally
covered to avoid contamination caused
by the welding process.
Remove the protection film at the top plate
from the stainless steel sliding plate.
Insert the PTFE/bronze sliding plate into the
provided embedding of the base plate.
Apply the top plate slowly to the bearing.

LHG high temperature bearings: Apply the lower
top plate loosely onto the PTFE/bronze
sliding plate.
Either the heat protection plate must be positioned
centred onto the lower top plate or it
must be fixed in the upper top plate to avoid
displacement and/or dislodgement.
Apply the upper top plate with the heat isolation
plate onto the bearing.
Apply the upper construction slowly onto the
overall bearing and weld fix.
Apply the top plate slowly to the bearing.
