Slit Coupling, Set Screw, Long, Bores 8x5mm, OD 20.0mm, Aluminum

This high-performance Slit Coupling is designed for demanding applications that require zero-backlash and high torsional stiffness. Made from a single piece of aluminum, it features two sets of slit cuts for low inertia and no maintenance. With a balanced design and high-speed capability up to 15,000 RPM, it reduces vibration and protects small sensitive bearings. Suitable for applications with high misalignment and torque requirements, this coupling excels in industries such as robotics, aerospace, and medical equipment. Its long design provides increased torque and misalignment capabilities, making it an ideal solution for precision machinery and high-speed machinery.

Top product features:

  • Zero-backlash design for reduced vibration at high speeds
  • Has two sets of slit cuts for low inertia, no maintenance, and high torsional stiffness
  • Accommodates all forms of misalignment with low bearing loads to protect sensitive bearings

Top product applications:

  • High-speed machinery such as spindles and drill presses
  • High-precision applications such as optical and laser equipment
  • Power transmission systems in aerospace and defense industries
This Ruland supplied slit coupling is zero-backlash and has a balanced design for reduced vibration at high speeds up to 15,000 RPM. The coupling is made from a single piece of aluminum and has two sets of slit cuts allowing for low inertia, no maintenance, and high torsional stiffness when compared to beam couplings. It is set screw style and has 8mm x 5mm bores, 20.0mm OD, and 26.00mm length. This long slit coupling has increased torque and misalignment capabilities when compared to short styles. It can accommodate all forms of misalignment with low bearing loads helping to protect small sensitive bearings. This slit coupling is manufactured by Reliance Precision Ltd. in their facility in County Cork, Ireland and is RoHS and REACH compliant.
