Ruland Aluminium Clamp Style Flexible Bellows Coupler 6 mm Bore 19.1 mm OD 30.2 mm Length MBC19-6-6-A

Ruland MBC19-6-6-A is a high-precision flexible bellows coupler designed for demanding mechanical power transmission applications. Featuring a 6 mm bore diameter on both ends, a 19.1 mm outer diameter, and a length of 30.2 mm, this coupler is engineered with anodized aluminum hubs and stainless steel bellows. The bellows provide flexibility to compensate for angular, parallel, and axial misalignments while transmitting torque with zero backlash.

The clamp style hubs allow for robust shaft attachment, eliminating slippage and enhancing positional accuracy, which is critical in stepper motor and servo applications. This coupler supports rotational speeds up to 10,000 RPM and a torque rating of 4.5 Nm, while exhibiting a low moment of inertia (0.898 x 10^-6 kg/m²), making it suitable for dynamic, high-speed environments.

The hardware complies with DIN 912 12.9 standards, ensuring enhanced strength and fatigue resistance. The product is made in the United States under strict manufacturing processes to maintain quality and consistency.

Constructed of anodized aluminum hubs and stainless steel bellows. Bores sized at 6 mm to fit precise shaft diameters. Clamp style delivers secure mechanical connection without backlash. Supports high speeds and torque with low vibration and inertia.

Flexibility compensates for misalignment in industrial machinery setups. Suitable for use in automation, robotics, servo mechanisms, and encoder applications. Resistant to environmental factors with operating temperatures from -40°C to 93°C.

Compact and lightweight design aids in reducing system weight and inertia. Manufactured under stringent quality controls in the USA.

This coupler is ideal for industrial, manufacturing, automation, and laboratory settings requiring precise rotational alignment and torque transmission. For additional compatible products, explore the Mechanical Power Transmission Couplers category at EnvMart.
