Ruland MBC33-8-8-A is an aluminium clamp-style flexible coupler designed for mechanical power transmission requiring precision and flexibility. The coupler features two anodized aluminium hubs combined with stainless steel bellows, enabling it to flex while maintaining rigidity under torsional loads.
This flexible coupling compensates for axial, angular (up to 1.5°), and parallel misalignments (up to 0.15mm), ensuring smooth operation without backlash. The clamp fastening system offers secure and easy installation between shafts with 8mm bore sizes on both sides.
The coupler has a 42.9mm length and 33.3mm outer diameter, supporting maximum rotational speeds of 10,000 rpm and a torque rating of 13.6 Nm, suitable for light-duty power transmission applications such as stepper and servo drives, encoders, and general mechanical power transmission tasks.
The bellows material is stainless steel, providing durability and flexibility at operating temperatures ranging from -40°C to 93°C. The hardware includes black-oiled alloy steel fasteners tested beyond DIN 912 12.9 standards, delivering high torque capabilities and corrosion resistance.
Durable anodized aluminium hubs combined with stainless steel bellows. Clamp style fastening for secure, backlash-free operation. Accepts axial, angular, and parallel misalignments effectively. High maximum speed and torque rating for versatile industrial applications.
Corrosion resistant black-oiled alloy steel fasteners. RoHS3 and REACH compliant with DIN 912 12.9 screw size M3.
This coupling is widely used in industrial, laboratory, and manufacturing environments for general-purpose light-duty power transmission, providing reliability and precise torque control.
