Ruland 50.8 mm Outer Diameter 25 mm Bore Stainless Steel Bellows Clamp Coupler 58.7 mm Length MBC51-25-25-A

Ruland MBC51-25-25-A is a precision flexible bellows coupling designed for mechanical power transmission applications requiring high torque and minimal backlash. Featuring a 50.8 mm outer diameter and 25 mm bore size, this coupler assures a balanced design to minimize vibrations during operation at speeds up to 10,000 rpm. Its 58.7 mm length, clamp-style fastening, and anodized aluminum hubs make it lightweight yet robust.

The stainless steel bellows flexibly accommodate axial, angular (2°), and parallel (0.25 mm) misalignments while remaining rigid under torsional loads, ensuring reliable coupling performance. The torque rating of 45.2 Nm supports light-duty stepper and servo drives, encoders, and general power transmission tasks in industrial, manufacturing, and automation environments.

It operates reliably within a temperature range of -40°C to 93°C and uses black-oiled alloy steel fasteners for enhanced strength and corrosion resistance. The product meets international standards including RoHS3 and REACH, demonstrating compliance with environmental and safety regulations.

The coupler length is precisely 58.7 mm for compact machinery integration. Clamp style fastening provides secure and easy assembly. Misalignment tolerances include angular up to 2°, parallel up to 0.25 mm, and axial up to 0.5 mm.

Constructed with anodized aluminum hubs ensuring lightweight durability. Stainless steel bellows ensure high flexibility and torsional rigidity. Maximum operating speed supports high rotation machinery up to 10,000 rpm. Corrosion resistant black-oiled alloy steel fasteners improve lifespan.

Torque rating of 45.2 Nm accommodates light-duty power transmission loads. RoHS3, REACH, and DIN 912 12.9 compliance ensures regulatory adherence.

This flexible coupling is ideal for applications such as stepper and servo drives, encoders, and general-purpose light-duty mechanical power transmission tasks in industrial, laboratory, agricultural, and manufacturing sectors. Its well-balanced design reduces vibration and enhances machinery life span.
