Fabric-Reinforced Oil-Resistant Buna-N Rubber Sheets

To maintain their size and shape under heavy compression, these sheets have one layer of nylon fabric for every 1/16” of thickness. Use them as flange gaskets and diaphragm packing. Buna-N is also known as nitrile, NBR, and acrylonitrile butadiene. It resists fuel oil, hydraulic oil, ethylene glycol, and grease.

Fabric-Reinforced Vibration-Damping Pad Packs for Heavy Machinery

Shield surfaces from impact, reduce vibration and noise, and stabilize connection points with these packs of pads—they’re reinforced with fabric to endure extreme compression without deforming. Use them to mount heavy machinery such as forging hammers, stamping presses, rock crushers, shearing machines, and vibratory feeders. They also form consistent weight-bearing areas between steel and concrete columns, even if there are surface deformities. Made of nitrile—often known as NBR, Buna-N, and acrylonitrile butadiene—they resist oil and solvents. All meet MIL-C-882, which is a test of the quality, density, capacity, compression, deflection, and oil- and mold-resistance of materials used in military construction. They’re also known as bearing pads.

Fabric-Reinforced Vibration-Damping Pads for Heavy Machinery


Reinforced with fabric so extreme compression won’t deform them, these pads protect surfaces from impact, dampen vibration and noise, and act as stable connection points. Use them to mount forging hammers, stamping presses, rock crushers, shearing machines, vibratory feeders, and other heavy machinery. They also create uniform weight-bearing areas between steel and concrete columns, even if there are surface irregularities. Made of nitrile—also known as NBR, Buna-N, and acrylonitrile butadiene—they resist oil and solvents. All meet MIL-C-882, which tests the quality, density, capacity, compression, deflection, and oil- and mold-resistance of materials used in military construction. They’re commonly known as bearing pads.
