Two-Piece Rigid Muff Sleeve Coupling for Servo Motors (0.25 Inch)

Muff Coupling, also known as Sleeve Coupling or Split Muff Coupling, is one of the most reliable and widely used rigid shaft couplings for servo motors, stepper motors, and precision motion systems. Designed in a two-piece split construction, these couplings allow easy mounting and dismounting without removing the motor or driven equipment. They provide torsional stiffness, zero backlash, and accurate torque transmission in demanding automation and power transmission applications. Key Features of Muff Coupling for Servo Motors Rigid Two-Piece Sleeve Design – ensures strong grip and easy assembly. Zero Backlash & High Torque Transmission – suitable for servo & stepper drives. Durable Material Options – Alloy Steel, Stainless Steel (SS304/SS316), Hardened Steel, Aluminum. Compact & High Precision – concentric bores reduce vibration and misalignment. Custom Options – keyway, set-screw, clamping hub, shrink disc mounting. Applications – robotics, CNC machines, conveyors, packaging, printing, textile machinery, medical automation, semiconductor equipment. Muff / Rigid Servo Couplings1.
