Slit Coupling, Set Screw, Long, Bores 0.250"x6mm, OD 0.787", Aluminum

This long slit coupling is ideal for high-speed applications up to 7,500 RPM, providing reduced vibration and increased torque and misalignment capabilities compared to short styles. Its zero-backlash design and balanced construction make it suitable for use in precision machinery, such as CNC equipment, laser cutting machines, and other sensitive applications that require low bearing loads. The coupling's low inertia and high torsional stiffness also make it a great option for applications with high shock loads or rapid acceleration. Its compact size and durable aluminum construction make it a reliable choice for a variety of industries, including aerospace, automotive, and medical.

Top product features:

  • Zero-backlash design for reduced vibration at high speeds up to 7,500 RPM.
  • Balanced design with 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 small sensitive bearings.

Top product applications:

  • High-speed machinery
  • Power transmission systems
  • Precision machinery assembly
This Ruland supplied slit coupling is zero-backlash and has a balanced design for reduced vibration at high speeds up to 7,500 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 0.250" x 6mm bores, 0.787" (20.0mm) OD, and 1.024" (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.
