Ruland continues to expand its motion control coupling product line by introducing bellows couplings with increased misalignment capabilities. These new bellows couplings complement Ruland’s existing high-stiffness line by offering equivalent torque with greater misalignment flexibility.

Ruland now offers bellows and double disc couplings with bore sizes up to 45 mm or 1-3/4 in for use in systems with torque up to 158 Nm (1,4000 in-lbs).

Ruland Manufacturing now offers rigid couplings with inch-to-metric bores as a standard product, giving users a wider range of off-the-shelf couplings.

Ruland has released mountable shaft collars with face holes for applications where the shaft collar needs to be directly mounted to a component such as a pulley, sprocket, or metallic plate. The shaft collars are available with drilled face holes that give the user flexibility in mounting hardware, or tapped holes that match the standard screw threading of the collar for ease of installation.

Ruland zero-backlash jaw couplings are a three-piece assembly designed to accommodate high acceleration and deceleration curves that result in peak torque. Jaw couplings are ideal for systems that experience hard starts, hard stops, or reversals, including in medical, semiconductor, test and measurement, and robotics applications.

Ruland beam couplings are ideal for surgical, warehouse, and industrial robotics due to their increased torque and torsional stiffness and ability to accommodate all forms of misalignment. Ruland manufactures four-beam couplings for encoders and six-beam couplings for light-duty power transmission, such as connecting a stepper or servo motor to a lead screw. This allows robotic designers to design a standard beam coupling into most systems.
