Thermoplastic Insert Couplings

altR+W America (Bensenville, IL) has introduced the SERVOMAX TX1 series of molded thermoplastic insert couplings that are suitable for pump drive and servo applications. The couplings are chemical-compatible and tolerant to heat, and have an elastomer element that is press-fit between two molded coupling halves, providing zero backlash and concentricity. The elastomer insert is available in various shore values. The TX1 series is designed for a pure keyway connection and is bored to customer specifications. Shaft mounting is achieved via keyway and a set screw. Sizes are available for torque capacities ranging from 2 Nm to 660 Nm, and bore diameters from 8 to 45 mm and 0.375 to 1.75".
