P-Series Four Beam Couplings

P-series beam couplings are designed specifically for precision applications, such as encoders and tachometers that use delicate components. The small bearings on these components make low radial forces essential to longevity and continued high performance. They provide extra flexibility to yield reduced bearing loads. These flexible couplings are shorter than the F-series six beam couplings and conform to industry standard lengths, fitting into confined spaces and allowing for easy retrofits in existing equipment. At the same time, the helical cut pattern continues to provide excellent torque capabilities and low wind-up. P-series beam couplings are manufactured from a single piece of 7075 aluminum for lightweight and low inertia or 303 stainless steel for increased torque capabilities.
