The SP-series of machine pads designed to insulate machinery against the adverse effects of impact, vibration, structure-borne noise and slippage, are used for heavy machinery including metal forming equipment, large presses and power generation equipment. The series is said to be resistant to all types of grease, acid, oil and cooling emulsion, typically found in manufacturing environments. The machines pads also are designed to offer a tolerance to a range of temperature variations and are designed to meet specific thickness and shape requirements. All pads are made of nitrile rubber and contain no PVC or silicon. The series is available in five classifications, each pad offering their own specific hardness, natural frequency and load-bearing characteristics. The series holds load capacities from 25-300 PSI.
