Ruland beam couplings are a good starting point for applications that require a flexible coupling. They can accommodate all forms of misalignment and have higher torque capabilities and reduced wind-up than single beam couplings. Ruland beam couplings are machined from a single piece of material and have two sets of spiral cuts allowing for superior parallel misalignment capabilities when compared to single beam couplings. They also have a balanced design for reduced vibration and higher RPM capabilities.This P-series four beam coupling is manufactured from 7075 aluminum for lightweight and low inertia. It is well suited for precision applications that use delicate components such as encoders or tachometers. Four beam couplings are shorter than six beam couplings to conform to industry standard lengths, fitting into confined spaces and allowing for easy retrofits in existing equipment. They have increased flexibility to yield reduced bearing loads. The multiple beam spiral cut pattern provides for higher torque capabilities and reduced windup compared to single beam couplings.Ruland beam couplings are carefully made from select bar stock sourced exclusively from North American mills and are machined to a fine burr-free finish. Hardware tests beyond DIN 912 12.9 standards for maximum torqueing capabilities. Ruland, founded in 1937, manufactures all products in our Marlborough, MA USA factory under strict controls using proprietary processes. Beam couplings are RoHS2 and REACH compliant.
