Slit Coupling, Set Screw, Long, Bores 0.250"x0.250", OD 0.512", Alum
The Ruland Slit Coupling is a high-performance, zero-backlash coupling ideal for applications requiring low inertia, high torsional stiffness, and reduced vibration at high speeds up to 12,000 RPM. Its balanced design and two sets of slit cuts enable low bearing loads, protecting sensitive bearings and accommodating all forms of misalignment. Suitable for use in precision machinery, medical devices, and other applications where low vibration and high torque are critical. This long slit coupling offers increased torque and misalignment capabilities compared to short styles, making it an excellent choice for demanding industrial and OEM applications.
Top product features:
- Zero-backlash design for reduced vibration at high speeds
- Balanced 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
Top product applications:
- High-speed machinery applications that require zero-backlash and high torsional stiffness
- Applications that demand low vibration and misalignment capabilities
- Sensitive bearing protection in applications with all forms of misalignment
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 set screw style and has 0.250" x 0.250" bores, 0.512" OD, and 0.787" 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.
