Ruland Manufacturing 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 Manufacturing now offers bellows and double disc couplings with bore sizes up to 1-3/4 in or 45 mm for use in systems with torque up to 1,4000 in-lbs. (158 Nm). High torque applications commonly found in precision semiconductor, solar, conveyor, and factory automation applications often use these shaft sizes. Ruland disc and bellows couplings accommodate all forms of misalignment, are zero-backlash, and have a balanced design for reduced vibration at speeds up to 10,000 rpm.

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. This expansion is the latest addition to the company's inch-to-metric, standard coupling product line that includes seven types of motion-control couplings and universal joints. Instead of re-machining or ordering custom-made couplings, using off-the-shelf, inch-to-metric rigid couplings saves time and money.

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 servomotor to a lead screw. This allows robotic designers to design a standard beam coupling into most systems.

Ruland recently expanded their range of quick clamping shaft collars with clamping lever to include bore sizes up to 3 inches or 80 mm. These shaft collars allow the user to install, remove, or reposition the collar without the use of tools. The user simply turns the lever to loosen and tighten the collar on the shaft.
