T Type Tooth Neoprene timing belts: The extra highly flexible neoprene backing provides excellent abrasion and wear resistance, important if power is transmitted from the back of the belt. Backing also guards the tensile cords against oil, grease, dirt and moisture. These belts constructed with fiberglas tensile cords which quarantee diemensional stability to eliminate take up adjustments. Teeths are formed nicely and correctly, oil and heat resistant neoprene teeth have a shear resistance equal to the tensile strength of the belt. Tooth design and tight manufacturing tolerances provide a constant circular pitch to assure full surface contact between belt and pulley for good running charecteristics.
