These shaft-mounted fluid couplings are engineered for axially compact drive spaces, featuring a flexible coupling on one end. Available in multiple configurations (SM, SMD, SM-DX), they offer enhanced adaptability for industrial applications ranging from mining to high-power transmission. SM types use rubber couplings, while SMD and SM-DX include delay fill chambers for advanced torque control. Designed to ensure optimal shaft alignment and protection, they also feature thermal safety options and compatibility with a wide range of shaft sizes.
