Building structural design has taken a considerable change
over the last decade. The sizes of spans have grown bigger,
difference of internal and external temperature has become
greater and global warming has changed climatic changes. These
factors have exerted great demand on elastomeric bearing design
and requirements. New polymer types and combinations with
Stainless Steel have paved way for new designs. Thus from ARP we
offer a combination of elastomeric sliding bearing with ptfe
known as ARP-NEOSLIDEPAD for PTFE Teflon sliding bearing
requirements.
ARP-NEOSLIDEPAD - (PTFE Sliding bearing system with Stainless
Steel Top and Neoprene Protective Seal) are specially designed,
manufactured and assembled with a combination of polyamide or
steel reinforced neoprene bearing pad with PTFE top and a SS 316
plate sliding over top of it and whole unit protected with a soft
neoprene seal. These ptfe sliding bearings are self lubricated
and can be used for the application of sliding bearings, teflon
sliding bearings, ptfe sliding skid pads and teflon sliding
structural bearings We are one of the fmw bearing manufacturer
who are specialized in hot bonded ptfe to Carbon Steel.
These teflon pads can be used for the application for skid
pads, were heavy duty ptfe skid pads or teflon launch bearings
for bridges to avoid expensive scaffoldings. Ptfe teflon are
available as plain teflon sheets or with dimples, dimpled to hold
silicon lubrication used. These dimpled ptfe skid pads are hot
bonded to bas mild steel. Using a combination of Steel reinforced
Neoprene, PTFE Teflon, Stainless Steel and Soft Neoprene
protective Seal, our ARP-NEOSLIDEPAD permits displacement of
± 25 mm. Maximum permissible pressure for steel reinforced
pads will be 15N/mm². The total size of ptfe sliding pads
will be minimum 60 mm>Neoprene /PTFE bearing.
The properties of ARP-NEOSLIDEPAD are exceptionally suited
for reduction of bearing height compared to Laminated Elastomeric
bearings, at the same time retains horizontal displacement and
rotation.
Steel Reinforced Neoprene Elastomeric Bearing is bonded on
top side with Ptfe (Teflon). Top sliding plate over Ptfe will be
Stainless Steel 316 with mirror finish on one side. Un-filled
Ptfe teflon sheet offered has low friction of coefficient 0.05
and with mirror finished steel, and being self lubricated, long
term smooth sliding even at high pressure of 15N/mm².
Neoprene bearing is covered in all sided by a soft Neoprene seal
from protection of concrete seeps.
Size of this Protective Neoprene seal being greater than
required movement; mirror finished bottom side of SS sheet will
be protected from any scratches due to dirt accumulation in long
service. Stainless Steel Top plate is placed in location over
Neoprene Bearing using High Strength Adhesive tape. Complete
system will be packed in thick polyethylene and delivered as a
unit. Cut off area on both top and bottom sides will be marked on
polyethylene and can be removed at the time of casting. Less
expensive compared to heavy sliding bearing. Easy to install with
in-situe concrete. Fit and forget system, we offer 50 years
warranty Manufactured in UAE, less delivery time.
Some salient features and benefits of ARP-NEOSLIDEPAD;
(1) Do not have a shape limit factor can be custom
manufactured to your requirements.(2) Exhibit relatively high
damping (C/Cc -.14) (3) Creep effects are reduced to a limit of
5% of original thickness (4) Operating temperature limits are
-65°F (-55°C) to 200°F (95°C) (5) Unusually high
compressive strength -5Kg/cm² for polyamide reinforced pads
and 15Kg/cm² for steel reinforced pads. (6) Impervious to
most oil and solvent traces (7) Resist effects of steam, water,
mildew and brine (8) Can be supplied as a system in nominal
thickness of 10 mm up to 50 mm.(9) Combination of both vertical
load and horizontal movements with rotation (10) Faster delivery
and accepted quality: Manufactured in UAE.
Some practical aspects and considerations when using AR
-NEOSLIDEPAD:
Provides vertical stability and allow controlled motion,
Should be used with flat rigid support for best performance
Recommend applying of a high strength epoxy mortar on bottom of
Pad and an Epoxy resin with aggregate on top of Stainless Steel
plate to work as a key and Connections to isolating system should
be made flexible excellent for pipe supports
Some typical applications ARP-NEOSLIDEPAD system
include:
Buildings
Bridges
Floor isolations
Heavy Loading Areas
Military
Pipe supports
Mining
Pipelines
Railroad and Transit
Our quality assurance.
Under one roof with stringent quality control we manufacture
bridge bearings, neoprene bridge bearings, ptfe sliding bearing,
sliding bearing, sliding stainless steel bearing, ptfe pipe
supports, Teflon bearings, arp-neoslidepad, and Teflon sheet to
AASHTO / BS / DIN specifications in the Middle East U.A.E.

Thank you very much for visiting us.
Bearing Load Testing.
We are the first and only laminated bearing manufacturing
facility in Middle East to have an in-house bearing testing
facility to carry out tests confirming to AASHTO
specification in accordance with Acceptance Testing on either
Level I or Level II as well as Short/Long-Duration Compression
Test. Our bearing testing machine can test bearings to Vertical load of 4200
kN with horizontal shear load up to 400kN and movement to 100
mm.
Let us verify ..load
calculations.. for your bearings. On receipt of corbel
size, and load details of your requirements, and we can provide
