Description
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 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.
