Ruland Manufacturing has expanded its line of bellows couplings to include an outer diameter of 2-1/4-in. (57 mm), allowing for larger bore sizes and increased torque and torsional stiffness capabilities. Designers prefer to specify bellows couplings in servo-driven systems due to their high accuracy and repeatability. This size expansion now allows for bore sizes up […]

Bellows couplings for printing applications
Ruland, Marlborough, Mass. manufactures bellows couplings with high torsional stiffness that can accommodate all forms of misalignment and are well suited for large format printers, 3D printers, offset printers, web converting equipment, and print finishing equipment. Ruland’s bellows couplings are comprised of two anodized aluminum hubs and a stainless steel bellows, for a lightweight, low […]
Pick the right coupling for each high tech application
Selecting the right coupling for your application is critical to system safety and reliability, says Ruland Manufacturing Co. Inc., Marlborough, Mass., which manufactures a diverse couplings product line while providing technical support and application experience. Ruland’s coupling line includes rigid couplings with precision honed bores and five types of zero-backlash couplings: beam, bellows, disc, jaw, […]
A look at coupling selection tools
I often think of how the Internet has changed our lives, and how it has made it so much simpler in many ways. For example, buying a rare item meant either hoping your local store had it in stock or paging through catalogs. Going on a trip used to mean highlighting a route on a […]
Servo couplings for a wide variety of applications
Rigid couplings have high torque capacity, torsional stiffness, and zero backlash. Ruland Manufacturing Co., Inc. straight bore rigid couplings have precision honed bores for proper fit and alignment. Proprietary Nypatch coating is used on hardware to resist vibration and maintain holding power. Two-piece styles feature opposing screws for balancing, reducing vibration at higher speeds.
