Ruland Manufacturing (Marlborough, MA) has expanded its jaw coupling line to meet the demands of high-torque applications, now offering bore sizes up to 1-3/4 in or 45 mm and torque capacities of 2,655 in-lbs (300 Nm). These new jaw couplings are designed for use in precision systems with high deceleration and acceleration curves, such as those found in semiconductor, solar, conveyor, and warehouse automation applications.
With zero-backlash, industry-leading misalignment capabilities, and a balanced design that reduces vibration at speeds up to 8,000 rpm, Ruland jaw couplings deliver optimal performance for demanding environments.
Ruland jaw couplings offer the highest size-for-size torque and torsional stiffness among flexible couplings in the Ruland product line. They consist of two precision-machined aluminum hubs connected by an elastomeric element called the spider. The curved jaw profile of the hubs presses fits with the spider, ensuring zero-backlash performance. Made from advanced polyurethane material, the spider damps impulse loads, minimizing shock to the motor and other sensitive equipment.
