Metal bellows couplings are the premier choice for applications demanding high dynamic positioning, making them ideal for servo drives. They provide an entirely backlash-free operation and exceptional torsional rigidity. With maintenance-free performance, outstanding fatigue resistance, and minimal restoring forces even under misalignment, these couplings deliver reliability and precision. KBK’s modular system offers unparalleled versatility, ensuring the perfect coupling solution for every assembly requirement.
Options: Available in a wide range of configurations to meet diverse assembly requirements, with a modular hub and clamping system that covers shaft diameters from 1 mm to 100 mm and torque capacities from 0.05 Nm to 5,000 Nm. Stainless steel clamp variants are also available, providing corrosion resistance and long service life in washdown or harsh environments.
Hub styles include set-screw, collet clamp, split-hub, expanding clamp, and conical hub designs, allowing for flexible mounting options and adaptability across various shaft and installation configurations.
Mounting options include standard shaft-to-shaft and flange-mount designs, as well as axially pluggable versions, enabling installation flexibility based on space constraints and assembly access.
These couplings are available across a wide range of torque and shaft diameter combinations to support different operational demands. Designed for reliability across demanding duty cycles, metal bellows couplings operate maintenance-free with no lubrication or wear parts required.
Additional features include a broad range of shaft diameters and torque capacities to fit specific application requirements, along with axially pluggable and infinitely adjustable variants for installations with limited access or precise timing needs.
