Slit Coupling, Clamp, Long, Bores 4mmx0.125", OD 0.512", Aluminum

This high-performance Ruland Slit Coupling is ideal for applications requiring high-speed operation, low vibration, and precise torque transmission. Its zero-backlash design and balanced construction enable smooth operation up to 12,000 RPM, making it suitable for demanding applications such as high-speed machinery, medical equipment, and precision instruments. The coupling's low inertia and high torsional stiffness also minimize wear and tear on bearings, extending their lifespan. With its ability to accommodate all forms of misalignment, this slit coupling is perfect for applications with complex mechanical systems, ensuring reliable and efficient operation.

Top product features:

  • Zero-backlash design for reduced vibration at high speeds up to 12,000 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
  • Precision instrument manufacturing
  • Automotive engine testing equipment
This Ruland supplied slit coupling is zero-backlash and has a balanced design for reduced vibration at high speeds up to 12,000 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 clamp style and has 4mm x 0.125" bores, 0.512" (13.0mm) OD, and 0.787" (20.00mm) 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.
