Emerson's Power Transmission Solutions business offers the System Plast 2257 Series side-flexing modular\nplastic belt for unit handling. The belt features a patent-pending universal\ndesign that allows both left and right turns, and S-curves. The Series 2257 belt is injection molded with the new proprietary\nNG Evo thermoplastic or long wearing XPG low-friction\nacetal. It is available in a 1 inch (25.4 mm) pitch, in standard widths of\n9 to 24 inches, with four different clip styles to meet the retention\nrequirements of the application. Rated for a maximum working load of 450 lb., it is ideal for unit handling applications where it can maintain product\norientation through turns. ", "The belt\nhandles a minimum radius as small as 17.13 inches, excellent for compact system\nlayouts or spiral conveyors, according to the company. Thermoplastic construction makes the\nbelt highly resistant to thermal changes, corrosive chemicals and\nabrasion. A low coefficient of friction\nand low moisture absorption allow conveyance of heavy loads with minimal\nhorsepower.", "NGEvo is a proprietary\nthermoplastic designed for high-speed running with low noise and energy\nrequirements. Based on original NG resin, the NG Evo\nhas a lower coefficient of friction, higher breaking load, greater elasticity\nand higher wear resistance. The companion Nolu-S wear strips and guides reduce friction even further.\nThey are made of a unique resin with a solid lubricant that reduces the coefficient of friction. The combination of NG Evo chain and Nolu-S wear strips can reduce a conveyor’s\nenergy requirements by up to 30%, with service life as much as five times greater.
