SORBTEX® Fabricated Pads, Washers, and Bushings
larger image
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 10,000 psi. Ultimate breakdown strengths in excess of 12,500 psi are routinely observed during surveillance testing. Pad thickness and configuration will affect the ultimate failure point of the material. This discussion of ultimate failure strength is provided to demonstrate the robustness of the product. Design loads are generally limited to 30% or less of the MIL-C882E minimum strength requirement.
Pads, bushing, and washers are all custom fabricated to meet the projects requirements. Voss Engineering, Inc.'s in-house resources, allow us to offer short lead times for parts with common features such as holes, slots, counterbores, chamfers, step shoulders and other similar requirements. In addition to common fabrication requirements, our capacity allows Voss to offer specialty items such as pads that are 40" wide and taper from 2-3/4" to 7/8" thick down the 126" length to high precision washers used in military aircraft.
