Renbrandt Y25X25X Flex-Mite Disc Coupling

The RENBRANDT Y25X25X Flex-Mite Disc Coupling is a zero-backlash, high-torsional-rigidity flexible disc coupling engineered for precise torque transmission in motion-control systems, including servo drives and encoder drives. It features aluminum or brass hubs with stainless-steel flex discs, a 1.0 in outer diameter (25.4 mm), and a 60 oz-in torque rating, supporting up to 5,000 RPM, with angular misalignment up to 3°, parallel misalignment of 0.015 in, and total indicator runout (TIR) of 0.030 in. The design delivers low bearing loads and corrosion resistance, enabling maintenance-free operation in robotics, CNC machinery, laser systems, optical instruments, and other precision equipment that requires exact shaft alignment and smooth torque transfer. Common replacements in this space include the RENBRANDT Y25X25Y Flex-Mite Disc Coupling and the Ruland MDR20-4-4 Double Disc Coupling, reflecting its role in high-accuracy motion-control applications.
