Ruland Flexible Coupler Aluminium Hub Bellows Steel, 19.1 mm OD 8 mm x 5 mm Bore, 30.2 mm Length, Clamp Style MBC19-8-5-A

Ruland MBC19-8-5-A is a high-precision flexible coupling engineered for mechanical power transmission applications where precise alignment and vibration reduction are critical. Featuring anodized aluminium clamp style hubs combined with a stainless steel bellows, this coupling provides torsional rigidity with zero backlash characteristics, ensuring accurate and reliable torque transfer.

The coupling’s balanced design allows operation up to 10,000 RPM, making it ideal for use in servo motors, stepper motors, and encoders that require precise positioning. Its unique bellows construction accommodates angular misalignment of up to 1.5 degrees, parallel misalignment up to 0.1 mm, and axial misalignment of 0.25 mm without losing performance or causing excessive wear.

With bore sizes of 8 mm and 5 mm respectively, and an overall length of 30.2 mm with a 19.1 mm outer diameter, this coupling suits compact and lightweight applications requiring high torque capacity. The torque rating of 4.5 Nm supports robust mechanical loads while maintaining operational integrity.

Manufactured using solid bar stock sourced from North American mills and assembled under strict quality controls in Ruland’s Marlborough, MA facility, the MBC19-8-5-A coupling meets industry standards including RoHS3, DIN 912 12.9, and REACH, ensuring compliance and environmental safety. This product's metric hardware simplifies installation in global systems.

Constructed with aluminium hubs and stainless steel bellows for durability. Designed for zero-backlash operation to ensure precision in motion transfer. Supports maximum speed up to 10,000 RPM, suitable for high-speed servo and stepper motors.

Accommodates angular, parallel, and axial misalignments effectively. Balanced design reduces vibration and wear, extending service life. Operating temperature range from -40°C to 93°C for use in diverse conditions. Rated torque capacity of 4.5 Nm for reliable mechanical performance.

Compliant with RoHS3, DIN 912 12.9, and REACH standards for safety and quality.

This coupling is suited for industrial, laboratory, manufacturing, robotics, and automation applications where precise power transmission and alignment compensation are required. Explore additional Ruland Flexible Couplers and related mechanical power transmission components available at EnvMart.
