X Series Flexible Beam Couplings

Cross Slot Couplings

The X-Series couplings offer a cost-effective balance between couplings that are too stiff radially and those not stiff enough torsionally for servo-type applications. It features high torsional stiffness, low radial loads, one-piece integrity, good flexibility, and zero backlash. Created for high-performance motion control systems, the X-Series incorporates two flexible element sets – combining greater end-to-end rotational accuracy with radial flexibility – in one design.

Beam Coupling Manufacturing & Configurations


Our X series beam couplings are produced using either 7075-T6 aluminum using either standard or specialty machining operations, depending on the application. Specialty materials and services are available for custom coupling production. Multiple attachment styles are available for added functionality. Torque range, bore ranges, operating temperatures, speed, and other performance factors will vary depending on the configuration chosen.

For more details on available coupling configurations, review the list below for a side-by-side comparison, view our Standard Coupling Comparison Guide below.
