14 best flexible bellows couplings

Flexible bellows couplings are mechanical devices used in various industries to connect two shafts, typically motor and driven shafts, while allowing for some degree of misalignment and torsional flexibility. They are often utilized in applications where precision and reliability are crucial, such as in industrial machinery, automation systems, and aerospace.

Here are some key characteristics and information about flexible bellows couplings:

  1. Misalignment Compensation: One of the primary functions of a flexible bellows coupling is to compensate for misalignment between two shafts. These misalignments can be angular, parallel, or a combination of both. By accommodating these misalignments, bellows couplings help reduce wear and vibration in the connected machinery.

  2. Torsional Flexibility: Flexible bellows couplings can also provide torsional flexibility. This means they can absorb shocks and vibrations, which helps protect the connected components from damage and extends their lifespan.

  3. Materials: Bellows couplings are typically made from materials like stainless steel, aluminum, or other alloys. The choice of material depends on the specific application and the environment in which the coupling will operate.

  4. Design: Bellows couplings consist of a series of thin-walled metal bellows. These bellows are designed to flex and absorb misalignment and torsional loads. The ends of the bellows are attached to hubs that connect to the shafts. Some designs may incorporate additional elements like set screws or clamps for secure attachment.

  5. Zero Backlash: Many bellows couplings are designed to have zero backlash, meaning there is no play or lost motion when transmitting motion from one shaft to another.This is important in applications where precision is critical.

  6. Maintenance: Bellows couplings are generally low-maintenance components. However, they should be inspected periodically for wear and fatigue, especially in high-stress applications.

  7. Applications: These couplings are used in a wide range of applications, including CNC machinery, robotics, pumps, and more. They are particularly valuable in situations where precise motion control and the ability to withstand misalignment are required.

Flexible bellows couplings play a crucial role in ensuring the smooth and efficient operation of machinery and equipment by reducing stress on connected components and extending their service life. Their ability to handle misalignment and torsional loads makes them an essential part of various industrial systems.

Ruland BC16-6-4-A 2024 or 7075 Aluminum Hubs Bellows Coupling, Clamp Style, 0.375" x 0.250" Bores, 1.000" OD

Ruland

Product description

Ruland bellows couplings are zero-backlash, torsionally stiff, and have a balanced design. They are made from black anodized aluminum hubs and stainless steel bellows to offer superior performance in precision servo applications. The stainless steel bellows are ideal for transmitting torque due to their thin walls allowing the coupling to easily flex while remaining rigid under torsional loads. Bellows couplings can accommodate all forms of misalignment – angular, parallel, and axial motion.

Combining aluminum hubs with stainless steel bellows results in a lightweight, low inertia coupling that is well suited for precision applications found in a variety of industries including semiconductor, solar, printing, packaging, and machine tools. Bellows couplings have no moving parts ensuring a long maintenance-free life. Ruland uses a balanced design to reduce vibration in high RPM applications of up to 10,000 PRM.

Ruland bellows couplings are carefully made from select bar stock sourced exclusively from North American mills and are machined to a fine burr-free finish. Hardware tests beyond DIN 912 12.9 standards for maximum torqueing capabilities. Ruland, founded in 1937, manufactures all products in our Marlborough, MA USA factory under strict controls using proprietary processes. Bellows couplings are RoHS2 and REACH compliant.

User questions & answers

Question: I want to use this above ground on a mis-aligned 1" PVC pipe that broke after the backflow preventer on my sprinkler system - recommended
Answer: 4.3 psi test presure
Question: Is the Outside diameter of this the same as rigid 1 inch pvc? I want to cut a section out and glue it into 1 inch pvc fittings. Thanks
Answer: Local codes apply in all cases first before you attempt any advise. If you need length on a one way drain from a washing machine or sink try a check valve that can be easily inspected if it clogs with pipe sludge. Otherwise, get 2 couplings and cut in a section of common pipe and score the inside edges of pipe at an angle to prevent hair and the such collecting in the extended section. YouTube is a great help for a visual on this.
Question: when measuring your sprinklers white schedule 40 sprinkler pipe how much extra pipe do you need to fit into 3/4" PVC Lock fitting
Answer: 1 1/2 inch PVC pipe on one end clamped and a 1 1/2 inch copper pipe on the other end clamped should work. Do not use glue, clamp snugly. Recommend getting a spare coupling for future use.
Question: Can this be used for natural gas line
Answer: Yes or you can us a nohub
