Ruland Bellows Coupler 19.1 mm OD, 5 mm Bore x 5 mm Bore, 30.2 mm Length, Clamp Style, Aluminium Hub, Stainless MBC19-5-5-A

Ruland MBC19-5-5-A bellows coupler is engineered for precision mechanical power transmission applications, featuring a 19.1 mm outer diameter with 5 mm bores on both sides and a compact 30.2 mm length. Designed with anodized aluminium hubs and stainless steel bellows, it ensures zero backlash and a balanced structure to minimize vibrations during high-speed operation up to 10,000 RPM.

This flexible coupling accommodates various misalignments including angular displacement of 1.5 degrees, parallel misalignment of 0.1 mm, and axial movement up to 0.25 mm, making it suitable for demanding servo and encoder systems requiring high torsional stiffness. The torque rating of 4.5 Nm and low moment of inertia (0.902 x 10^-6 kg/m²) enable responsive and precise positioning.

Constructed to meet stringent industry standards like REACH, DIN 912 12.9, and RoHS3, the coupler employs metric M2.5 screws and a clamp-style hub for secure assembly. It is manufactured in the United States from solid bar stock sourced exclusively from North American mills, emphasizing quality and durability.

This coupling is ideal for industrial machinery, automation equipment, laboratory instruments, and robotics where precise torque transmission and misalignment compensation are critical. Its ability to perform reliably within a temperature range of -40°C to 93°C extends its usability across various environmental conditions.

Features anodized aluminium hubs and stainless steel bellows for durability. Facilitates zero-backlash and balanced design to reduce vibrations at speeds up to 10,000 RPM. Accommodates misalignment: angular (1.5°), parallel (0.1 mm), and axial (0.25 mm).

Supports torque ratings up to 4.5 Nm ensuring torsional rigidity. Suitable for precise positioning in stepper servo and encoder applications. Constructed from solid bar stock manufactured under strict quality controls in the United States.

Complies with REACH, DIN 912 12.9, and RoHS3 standards. Equipped with M2.5 metric hardware for secure clamp-style installation. Operates reliably between -40°C and 93°C temperatures.
