Plastic Bellows Couplings Plastic Bellows Couplings BELLOWFLEX Max. nominal torque [N·m] Bore ranges [mm] Operating temperature [℃ ] Drive High flexibility High damping 1.5 φ3 〜 12 −20 〜 60 Induction motor, stepper motor, encoder Automated teller machines, inspection equipment, printing machinery Plastic Bellows Coupling Ideal for Stepper Motors and Encoders Bellows couplings that use a plastic (polyester resin) boot with plenty of elasticity in order to achieve high damping performance and extremely small counterforce from mounting misalignment. A compact design that unitizes an aluminum alloy hub and plastic boot means there is no backlash. Main Features ■ Allows Angular Deflection up to 10° ■ Extremely Small Counterforce due to Misalignment (Reference) Structure and Materials Hub material: Aluminum alloy Boot material: Polyester resin Hexagon head set screw material: Alloy steel for machine structural use Surface finishing: Black coating 1

Specications Torque Static torsional stiffness [N·m/rad] SPEED CHANGERS ELECTROMAGNETIC CLUTCHES & BRAKES * Static torsional stiffness values given are from measurements taken at 20℃ * The moment of inertia and mass are measured for the minimum bore diameter. INVERTERS LINEAR SHAFT DRIVES TORQUE LIMITERS ROSTA * For combination with a CHP-20 that has a bore diameter of ø3, open the set screw to an angle of 120° . Metal Couplings * The recommended processing tolerance for paired mounting shafts is the h8 class. Metal Disc Standard bore diameter d1-d2 [mm] Metal Slit Couplings HELI-CAL Metal Coil...
