Description
The SICK KUP-0606-B (Part No. 5312981) is a high-precision bellows coupling designed for accurate torque transmission in motion control systems. With a compact design and 6 mm bore on both ends, it is ideal for connecting shafts in applications requiring high precision and minimal backlash.
Constructed with an aluminium hub and stainless steel bellows, this coupling provides excellent durability, flexibility, and resistance to mechanical stress. It offers high torsional stiffness (120 Nm/rad), ensuring precise positioning and reliable performance in servo-driven and encoder-based systems.
The coupling accommodates various shaft misalignments, including angular (up to 4°), parallel (0.25 mm), and axial (0.4 mm), making it suitable for real-world installation conditions. With a maximum speed of 10,000 rpm and torque rating of 80 Ncm, it is well-suited for high-speed, low-torque applications.
Designed for operation in demanding environments, it supports a wide temperature range from -30°C to 120°C. This makes the KUP-0606-B coupling an excellent choice for automation systems, robotics, packaging machinery, and precision equipment.
