Bellows Coupling
Ruland bellows couplings are comprised of two anodized aluminum hubs and a stainless steel bellows. This design creates a low inertia zero-backlash coupling with long life properties. The thin wall of the bellows allows the coupling to remain flexible under misalignment conditions while maintaining rigidity under torsional loads. Bellows couplings can accommodate all forms of misalignment and have a balanced design for reduced vibration at high speeds up to 10,000 RPM. They are best suited for applications with limited misalignment where high torque and precise positioning are required. All Ruland bellows couplings are carefully made from select North American bar stock in our Marlborough, MA USA factory under strict controls using proprietary processes and are RoHS3 and REACH compliant.
About
Bellows couplings with inch dimensions are available are available with clamp style hubs with or without keyways in bore sizes ranging from 1/8” to 1-3/4”. Stainless steel hubs and other custom features are available by special order.
Bellows couplings with metric dimensions are available with clamp style hubs with or without keyways in bore sizes ranging from 3mm to 45mm. Stainless steel hubs and other custom features are available by special order.
Bellows couplings with inch to metric bore combinations are available with clamp style hubs with or without keyways in bore dimensions ranging from 1/8" (3mm) to 1-3/4" (45mm). Stainless steel hubs and other custom features are available by special order.
Why Ruland?
- Speeds up to 10,000 RPMs with reduced vibrations due to our standard balanced design.
- Do not introduce misalignment causing high bearing loads because of proprietary assembly processes that maintain bore concentricity.
- High torque and torsional stiffness with industry-leading misalignment capabilities.
- Low inertia for use in highly responsive systems due to the use of high-grade lightweight 2024 t351 aluminum.
