A new series of slit-type plastic couplings feature UV resistance, and voltage and RF isolation. The S50TLC... Inch and Metric Series come in sizes 13, 19, and 25. The lightweight molded coupling replaces stainless/aluminum slit-type couplings with low cost and improved operation. There is no windup, backlash, or derating for reversing applications. A metal screw-to-metal nut design ensures a tight fit between the shaft and coupling and does not use threads cut into the molded piece.
Made of engineered polymer with stainless-steel fasteners, the couplings come in 0.125 to 0.500-in. bore sizes and range in length from 0.710 to 1.400 in. Their maximum temperature range is –4 to 284°F.
