Ruland Beam Coupling, 19mm Outside Diameter, 8mm Bore, 30.2mm Length Coupler

Ruland MBC19-8-8-A is a bellows coupling with 8mm x 8mm bores, 19.1mm OD, and 30.2mm length. It is zero-backlash and has a balanced design for reduced vibration at high speeds. MBC19-8-8-A is comprised of two anodized aluminium hubs and a stainless steel bellows. The bellows are able to flex while remaining rigid under torsional loads allowing for all types of misalignment to be accommodated. This bellows coupling is lightweight and has low inertia making it suitable for applications with speeds up to 10,000 RPM. Hardware is metric.Ruland manufactures MBC19-8-8-A to be torsionally rigid and an excellent fit for precise positioning stepper servo applications as well as encoders. It is machined from solid bar stock that is sourced exclusively from North American mills. MBC19-8-8-A is carefully manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
