Marlborough, MA - Ruland Manufacturing is now an authorized distributor for Controlflex couplings manufactured by Schmidt-Kupplung in Wolfenbüttel, Germany. This partnership will give Schmidt-Kupplung an expanded North American presence and Ruland a more complete zero-backlash coupling product line.

Controlflex couplings have a compact balanced design, are electrically isolating, and have high misalignment capabilities, making them an ideal fit for encoders or light duty power transmission applications. Equipment designers in industries such as packaging, semiconductor, solar, medical and automation benefit from the wide range of sizes and performance characteristics offered by these couplings.

Controlflex couplings are comprised of two anodized aluminum hubs joined by pins to a Delrin insert called the frog. Hubs are manufactured in standard widths for general purpose applications and thin widths for compact installations. The Delrin frog allows for a balance of rigidity to maintain position and flexibility for high misalignment capabilities. It is an efficient torque transmitting element with light bearing loads.

Controlflex couplings are manufactured in single and double frog styles, allowing for system design flexibility. Single frog couplings have high misalignment capabilities and fit in space restricted applications. Double frog styles offer higher torque and torsional stiffness capabilities. All styles have a balanced design for reduced vibration at speeds up to 25,000 rpm.

Controlflex couplings are available in clamp screw designs with or without keyways in inch, metric, and inch to metric bore sizes ranging from 1/8 inch (3 mm) to 1 ½ inches (40 mm). Hardware meets or exceeds DIN 912 12.9 standards for maximum torque capabilities.
