Product Description

The UMSBK15-45 shaft coupling, part of the UMSBK series coupling family, is a 45mm flexible coupling engineered for high-torque transmission and vibration damping in precision-driven applications. Designed with robust aluminum or stainless steel construction, it accommodates axial, angular, and radial misalignment, making it ideal for industrial machinery, automation systems, and robotics. The UMSBK15-45 supports direct connection between motors, pumps, and gearboxes with a rated torque capacity up to 120 Nm and operates within -30°C to +120°C. Its compact, maintenance-free design ensures durability, while the flexible elastomer insert minimizes wear. Key advantages include easy installation, noise reduction, and resistance to harsh environments, though its maximum rotational speed is limited to 5000 RPM.
