Slit Coupling, Set Screw, Long, Bores 7x5mm, OD 20.0mm, Aluminum

This zero-backlash slit coupling is designed for high-speed applications up to 15,000 RPM, reducing vibration and increasing torque and misalignment capabilities. Made from a single piece of aluminum, it features two sets of slit cuts for low inertia, no maintenance, and high torsional stiffness. Suitable for use in applications such as robotics, medical devices, and industrial machinery, it can accommodate all forms of misalignment with low bearing loads. Its compact design and RoHS and REACH compliance make it an ideal choice for manufacturers seeking a reliable and environmentally friendly solution. It is available for immediate shipment in quantities of one.

Top product features:

  • Zero-backlash design for reduced vibration at high speeds up to 15,000 RPM.
  • Two sets of slit cuts for low inertia, no maintenance, and high torsional stiffness when compared to beam couplings.
  • Accommodates all forms of misalignment with low bearing loads helping to protect small sensitive bearings.

Top product applications:

  • High-speed machinery applications requiring reduced vibration and high torsional stiffness
  • Power transmission systems in aerospace and defense industries
  • Automotive engine and transmission applications where high torque and misalignment capabilities are necessary
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 7mm 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.
