The Ruland High Stiffness Bellows Coupling is engineered for precision positioning applications, combining the durability of anodised aluminium hubs with a stainless steel bellows. Its unique design features fewer convolutions than typical couplings of comparable size, enhancing torsional stiffness while accommodating various forms of misalignment. This coupling operates effectively at speeds of up to 10,000 RPM, making it ideal for high speed applications. Manufactured in an ISO 9001:2015 certified facility in Marlborough, Massachusetts, it meets strict quality standards and complies with RoHS3, REACH, and Conflict Minerals regulations.
Engineered with a balanced design to minimise vibration
Constructed from lightweight materials for low inertia
Rated for high torque capabilities to handle demanding applications
Includes a seating torque of 9.5 Nm for secure fastening
Offers zero backlash performance for accurate motion control
Configured to accommodate both angular and parallel misalignment
Features a metric clamp screw for compatibility with various setups
Designed to operate within a wide temperature range enhancing versatility
