Product Description
Ruland MBC25-10-10-A Flexible Coupler is a precision mechanical power transmission component engineered for robust performance in industrial machinery. Featuring a 25.4 mm outer diameter and 10 mm bore, this clamp-style coupling has a length of 33.3 mm and is designed to connect shafts with zero backlash, ensuring accurate torque transfer and minimal vibration.
The coupling assembly includes two anodized aluminium hubs that provide lightweight strength, along with stainless steel bellows capable of flexing to accommodate axial, angular, and parallel misalignment without compromising torsional rigidity. This design enables efficient power transmission in demanding environments.
With a maximum permitted speed of 10,000 rpm and torque capacity of 6.8 Nm, this coupling is well suited for high-speed drive systems such as stepper and servo motors. Its low moment of inertia (2.708 x 10^-6 kg/m²) further reduces system inertia, optimizing dynamic response and control precision.
Operating temperature ranges from -40°C to 93°C allow reliable use across various industrial, automation, and manufacturing applications. The clamp fasteners are black-oiled alloy steel, tested beyond DIN 912 12.9 standards for superior strength and corrosion resistance. The product is compliant with RoHS3 and REACH regulations, assuring environmentally responsible material selection.
The clamping style coupling provides quick installation and easy shaft adjustment. Stainless steel bellows flex to offset misalignments and reduce stress on connected equipment. Suitable for light-duty power transmission in robotics, automation, and instrumentation.
Precision manufacturing delivers consistent performance for encoders and servo drives. International standards compliance supports global industrial requirements. Applications include stepper motors, servo drives, encoders, and general-purpose light-duty mechanical power transmission.
Discover a broad range of mechanical power transmission components and couplers in the EnvMart catalog to support your industrial machinery and automation needs.
