SORBTEX® Structural Bearing Pads and Expansion Bearing Assemblies

SORBTEX® Structural Bearing Pads and Expansion Bearing Assemblies


SORBTEX® is a layered rubber and fabric composite material that is used as an elastomeric bearing pad in a wide variety of structural bearing applications. SORBTEX® is manufactured to meet, and is tested in accordance with, the requirements of MIL-C-882E. SORBTEX® also meets the cotton-duck pad (CDP) requirements as discussed in AASHTO Section 14.7.6.1, Section 14.7.6.2, and AASHTO Section 18.10.1. In addition to the above noted globally recognized specification references, SORBTEX® is also identified by a multitude of state and corporate specifications and descriptive references. The most common descriptive references for SORBTEX® are: fabric pad, preformed pad, preformed fabric pad, cotton duct pad, cotton duck ...
SORBTEX® Fabricated Pads, Washers, and Bushings

SORBTEX® Fabricated Pads, Washers, and Bushings


SORBTEX® is a high quality rubber and layered fabric composite material that has the ability to absorb and dampen impact forces and dissipate vibrations in heavy equipment applications. SORBTEX® is manufactured and tested for compliance with MIL-C-882E. This specification insures that SORBTEX® will provide reliable load deflection characteristics. Additional benefits of MIL-C-882E compliance include: demonstrated resistance to delamination in an oil soaked environment and fungus growth resistance in a moist environment. SORBTEX® is also compliant with applicable sections of MIL-E-5272 and its successor specification.

SORBTEX® can offer ultimate breakdown strength in excess of the MIL-C-882E minimum breakdown strength limit of ...
VSB Series (PTFE/Steel) Slide Bearings

VSB Series (PTFE/Steel) Slide Bearings


VSB slide bearing systems offer a low profile solution for allowing relative movement between structural elements. Thermal cycles, seismic activity, variable loading conditions, and long term material changes are some of the conditions that must be accommodated by the structural system. Typical applications are at floor and roof framing connections along expansion joint lines in large structures, truss base plates, pipe supports, heat exchangers, and other process equipment.

VSB slide bearing systems are comprised of an upper and lower element. In the basic format, the sliding interface is PTFE to PTFE. The upper element is sized to provide full coverage of the lower element throughout the range of allowed movement. This ensures ...
NEOSORB® (AASHTO Grade Polychloroprene) Bearing Pads

NEOSORB® (AASHTO Grade Polychloroprene) Bearing Pads


NEOSORB® plain elastomeric (polychloroprene / neoprene) bearing pads are molded or cut to size from larger slabs to provide a low-cost, single element structural bearing. Plain elastomeric bearings are a cost effective option for applications with moderate load transfer and movement requirements. NEOSORB® pads accommodate surface irregularities, vertical load, and rotation through vertical deflection, while longitudinal movement is accommodated through shear deformation. These pads are suitable for use in pre-cast concrete, cast in place concrete, and steel framed structures.

NEOSORB® is available in all 3 standard AASHTO durometers: 50, 60, and 70, widths up to 48", and lengths up to 49 feet (+/- 1 ft). NEOSORB® is typically ...
FIBERLAST® - Omni-directional Random Oriented Fiber (ROF) Pads

FIBERLAST® - Omni-directional Random Oriented Fiber (ROF) Pads


FIBERLAST® is an advanced random oriented fiber (ROF) bearing pad material that is widely used in the industrial/commercial cast-in-place concrete and precast concrete construction industry. With a uniform compressive stress capacity of 2,000 psi, FIBERLAST® offers higher loading limits than traditional ROF materials (σ average = 1,500 psi) and AASHTO grade neoprene (σ average = 800 psi). FIBERLAST® is typically used in single element bearing pad applications with modest longitudinal movement requirements. The document titled " FIBERLAST® Plain Pad Catalog" contains a complete description of the evaluation and test program that was conducted to determine the product application recommendations. Occasionally, FIBERLAST® is used ...
VOSSCO® - Random Oriented Fiber (ROF) Pads

VOSSCO® - Random Oriented Fiber (ROF) Pads


VOSSCO® is constructed of a homogeneous mixture of approximately equal parts of new, un-vulcanized elastomer and unused synthetic fibers permanently bonded to assure lasting strength and stability. VOSSCO® is most often used in precast structures. VOSSCO® is also used as a structural bearing and bedding pad material in select state's Department of Transportation projects.

Typical VOSSCO® applications include double tee end plate pads, guard rail, hand rail, fence base plate pads, on clip angles under precast panels, and in strips under hollow core planks.

VOSSCO® is available in 1/8", 1/4", 3/8", and 1/2" thicknesses. 1/8" material is available in widths up 48" with lengths in excess of 48" are available. 1/8" material is ...
