    Beam Couplings for Encoders

    Ruland 4-beam couplings are manufactured from a single piece of aluminum or stainless steel with multiple spiral (helical) cuts allowing for a zero-backlash encoder coupling with higher accuracy and better overall misalignment capabilities than traditional single beam couplings. They are designed with extra flexibility to provide reduced bearing loads, which is critical in encoders which have small sensitive bearings. Ruland 4-beam couplings have a balanced design for reduced vibration at speeds up to 6,000 RPM. Ruland manufactures two series of 4-beam couplings, P and MW, giving designers a variety of performance and dimensional characteristics to choose from. Ruland manufactures 4-beam couplings in our Marlborough, Massachusetts factory with bore sizes ranging from 3/32” to 1/2” or 3mm to 12mm.
