Product Description
Ruland MOST25-8-A Aluminium Set Screw Style Flexible Coupler features a bore diameter of 8mm, outside diameter of 25.4mm, and hub length of 9.9mm, purpose-built for mechanical power transmission in industrial settings. This coupling type uses a set screw style securing method to attach securely to shafts, accommodating minor misalignments including 0.5° angular, 0.2mm parallel, and 0.1mm axial misalignment. Constructed from anodised aluminium, it is lightweight and resistant to corrosion, making it suitable for various industrial, manufacturing, and motion control applications.
Flexible couplings of this design consist of two aluminium hubs and a central torque disc, typically manufactured from acetal or nylon, which acts as a torque limiter by breaking cleanly to protect connected machinery against overload forces. The set screw hubs are ideal for coupling shafts with small axial and angular misalignments present, commonly employed in motion control equipment, including stepper or servo motors.
The coupler supports a maximum speed of 4500 rpm, ensuring capability for high-speed mechanical systems, while the keyway-free finish bore promotes smooth shaft engagement. The product complies with RoHS and REACH environmental standards and is produced in the United States, highlighting commitment to safety and quality.
Lightweight aluminium hubs provide corrosion resistance and durability. Set screw securing ensures ease of installation and reliable shaft retention. Accommodates minor axial, angular, and parallel shaft misalignments. Torque disc system protects equipment by acting as a torque limiter.
Complies with environmental standards RoHS and REACH. Suitable for use in light industrial, manufacturing, and motion control applications. Maximum rotational speed capacity of 4500 rpm supports high-speed operations. Two hubs and one torque disc needed per assembly; sold separately.
