Ruland offers rigid couplings that are designed for the demanding needs of packaging applications. They have precision honed bores, anti-vibration hardware, and opposing hardware on two-piece styles to ensure superior fit, alignment, and holding power. Rigid couplings from Ruland are available in a wide variety of sizes, styles, and materials to suit the needs of packaging applications such as case erectors, cartoners, baggers, web converters, and form, fill, seal equipment. Ruland rigid couplings are ideal for shaft to shaft connections and precise servo driven applications found in packaging as they do not introduce misalignment, vibration, or bearing noise into the system.
Straight bore rigid couplings from Ruland have precision honed bores for better fit, torque transmission, and alignment. The cross cut design accommodates slight deviations in the size of the shafts being connected for proper fit. Ruland uses the highest grade forged screws that test to or beyond industry standards for maximum performance. All Ruland clamp type rigid coupling hardware is supplied with proprietary Nypatch coating to resist vibration and maintain holding power. Nypatch provides even seating of the screw, repeated screw installations and prevents galling. Two-piece styles have opposing hardware for balancing, reduced vibration, and higher speed capabilities.
