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.
CAD files for stock and standard X Series beam couplings are available for download in MW OnDemand.
CUSTOM MANUFACTURING
Custom Electrical Contacts
Custom beam couplings or Helical couplings offer many benefits including, choice of material composition, simplification of assembly, and customizable attachments and tolerances suited to your specific end-use. MW specializes in custom component manufacturing, providing you with the right features to ensure proper performance. Whether you need to eliminate endplay or spring, ensure zero backlash, need to increase torsional stiffness, or reduce windup, we can create the right custom coupling for your specialized need made to your exact specifications.

Characteristics
Beam or Helical couplings are flexible shaft couplings designed to transmit torque between shafts. Due to their curved beam configurations which allow angular movement, they can accommodate misalignments and axial motion, unlike traditional rigid couplings.
Features
- Ideal for motion control applications (servo motors)
- Up to 10 times greater torsional stiffness than beam types
- Low-cost alternative to bellows types
Relief
- Major and minor diameter shafts may enter flexure area during operation
- Dark areas indicate relief within the coupling interior

STANDARD BEAM COUPLING MANUFACTURING & CONFIGURATIONS
Manufacturing
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.
