## High Torque and Flexible Alignment Solution in Ruland Beam Couplings

Ruland Manufacturing has added a new six-beam coupling design to its portfolio, offering higher torsional rigidity, expanded bore sizes, and increased alignment tolerance in precision motion systems. This innovation enhances mechanical performance and integration in servo and motion control applications.

Beam couplings play a critical role in automation, robotics, and medical devices by preventing shaft deformation during torque transmission and minimizing eccentric and angular alignment problems to ensure high accuracy. Ruland's new six-beam geometry increases torsional rigidity compared to single or four-beam models, while tolerating angular, axial, and parallel alignment errors over a wider range.

### Beam Coupling Features

• Six-beam structure consisting of two groups of three helical cuts
• Angular alignment tolerance supported up to 7 degrees
• Wide bore diameter options from 4 mm to 25 mm (5/32 inch to 1 inch)
• Long design provides high flexibility in center-to-center distances
• Corrosion resistance with anodized surface coating
• Adaptation to thermal expansion and structural deformations thanks to high axial alignment tolerance
• Manufactured from 2024-T51 aluminum
• Dimensional consistency and performance repeatability across all production batches

### Application Areas

These new beam couplings are specifically designed for use in encoders, positioning systems, robotic applications, medical devices, and automated equipment. They offer ideal performance in precision systems requiring repeatable motion, low backlash, and consistent torque transmission.

### Technological and Manufacturing Advantages

This product, added to Ruland's standard catalog, reduces engineers' need for custom coupling designs in applications requiring high torque and alignment flexibility. This simplifies the mechanical design process, shortens testing and approval times, and streamlines procurement processes.

Finally, the product is manufactured in the USA to national standards and with advanced machining methods, offering a high-quality and reliable solution. This new beam coupling design effectively addresses common mechanical problems in modern motion control systems with a standard product.
