This D20L25 aluminum flexible jaw coupling is a precision-engineered mechanical component designed to connect motor shafts with reliable torque transmission and smooth operation. Built from high-quality alloy, this spider-type flexible coupler features a compact 20mm outer diameter and 25mm length, making it an ideal fit for space-constrained CNC machines, 3D printers, and other automation equipment. The jaw and spider insert design effectively dampens shock loads, reduces vibration, and minimizes noise for smoother mechanical performance. It accommodates angular misalignment without sacrificing rotational accuracy, ensuring consistent power transfer between connected shafts. Available in a wide range of bore diameter combinations — including 3mm, 4mm, 5mm, 6mm, 6.35mm, 7mm, 8mm, and 10mm — this coupler offers versatile compatibility with various motor and shaft configurations. Set screws on each hub provide a secure, slip-resistant grip on the shaft. Whether you are building or upgrading a motion control system, this flexible jaw coupling delivers dependable performance in a compact, durable package.
