Description

This Ruland supplied slit coupling is zero-backlash and has a balanced design for reduced vibration at high speeds up to 20,000 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 0.313" x 7mm bores, 0.787" (20.0mm) OD, and 0.846" (21.50mm) length. This short style slit coupling can fit in confined spaces where the long style may not fit. 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.
