Ruland PCR10-3-2.5-A Clamping Beam Coupling, Polished Aluminum, Inch, 3/16" Bore A Diameter, 5/32" Bore B Diameter, 5/8" OD, 4/5" Length, 12 lb-in Nominal Torque

Higher torsional rigidity than commodity style single-beam coupling. Unique balanced clamp screw design reduces vibration while the cross cut increases clamping ability. Machined from a single piece of aluminum or stainless steel with multiple spiral cuts for higher torsional stiffness and torque capabilities than single beam couplings. Accommodate parallel misalignment, angular misalignment and axial motion. Two sets of cuts around center member better accommodate parallel misalignment than single beam couplings. Aluminum couplings made from 7075 aluminum for long life and low inertia.

• 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.
• Smaller bodies than six beam couplings allow them to fit in confined spaces.
• Zero-backlash and a balanced design for reduced vibration at speeds up to 6,000 RPM.
• Manufactured from 7075 aluminum for light weight and low inertia.
• 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.
