Ruland Manufacturing (Marlboro, MA) now offers rigid couplings with inch-to-metric bores as a standard product, giving users a wider range of off-the-shelf couplings. This expansion is the latest addition to the company's inch-to-metric, standard coupling product line that includes seven types of motion-control couplings and universal joints. Instead of re-machining or ordering custom-made couplings, using off-the-shelf, inch-to-metric rigid couplings saves time and money.
Ruland rigid couplings often are used to connect motors or gearboxes to ball screw or lead screw linear actuators. Many designers prefer them because they have higher accuracy and can transmit significantly more torque than equivalently sized flexible couplings. One-piece style couplings allow for a simpler installation, while the two-piece style has a balanced design for smoother operation at speeds up to 4000 rpm. Ruland supplies clamp-style couplings with premium hardware that test beyond ISO strength class 12.9 standards. They also have Ruland's proprietary Nypatch anti-vibration coating to maintain holding power and torque capabilities in most industrial operating environments.
