Ruland Manufacturing Introduces D-Series Six Beam Couplings
Ruland Manufacturing has introduced its new D-series of six beam couplings, expanding its beam coupling product line to offer one of the most complete selections of standard beam couplings available for precision motion control applications.
D-series beam couplings feature an expanded bore size range up to 1 in (25 mm), angular misalignment capability up to 7 degrees, and an anodized finish for improved corrosion resistance. The six beam design provides higher torsional stiffness compared to single or four beam couplings while maintaining high misalignment compensation.
Ruland manufactures D-series beam couplings with two sets of three helical cuts with a wide slot, allowing for high axial misalignment. They have the longest size-for-size length in the Ruland beam coupling line, making them ideal for applications with a wide distance between shaft ends.
With the addition of the D-Series, Ruland now offers standard beam coupling solutions suitable for the majority of light- to medium-duty servo and motion control applications. Engineers can select a standard coupling rather than specifying a custom component, simplifying design, qualification, and procurement.
Ruland D-Series beam couplings are carefully manufactured in the USA from meticulously selected 2024-T51 bar stock, using proprietary processes to ensure consistent product quality. They are available in bore sizes from 5/32 in. to 1 in. or 4 mm to 25 mm. The D-series is ideal for applications such as encoders, positioning systems, robotics, medical devices, and automation equipment, where accuracy and reliability are critical.
