Specification Brand : Ruland BulletPoint1 : Four beam couplings have higher torque and torsional stiffness than commodity style single beam couplings and are ideal for encoder, tachometer, and other light duty applications. BulletPoint2 : Smaller bodies than six beam couplings allow them to fit in confined spaces. BulletPoint3 : Zero-backlash and a balanced design for reduced vibration at speeds up to 6,000 RPM. BulletPoint4 : Manufactured from 7075 aluminum for light weight and low inertia. BulletPoint5 : Hardware exceeds DIN 912 12.9 standards for maximum torque capabilities. Ruland beam couplings are carefully made from select North American bar stock in our Marlborough, Massachusetts factory and are RoHS3 and REACH compliant.
