N.º de artículo M13, M-Series Non-Spacer Couplings En U.S. Tsubaki Inc.

The ATRA-FLEX® M-Series flexible couplings are designed to accommodate a wide range of industrial applications, offering a torque capacity up to 3,610,000 in-lbs and can handle shaft diameters up to 16 inches. These couplings feature a unique twist-and-lock ring that eliminates the need for fasteners or special tools, facilitating easy installation and maintenance. The rugged polyurethane insert effectively absorbs torsional shock and vibration while accommodating angular, parallel, and axial misalignment, thereby enhancing equipment longevity. Additionally, the couplings operate lubrication free, have no metal-to-metal contact and can withstand temperatures ranging from -60°F to 350°F. For applications requiring corrosion resistance, options include stainless steel components or a cost-effective nitrocarburized process known as OnyxShield™, as an alternative.
