12 best flexible disc couplings
Flexible disc couplings are mechanical devices used in various industrial applications to connect two shafts while allowing for some degree of flexibility and misalignment. They fall under the category of flexible couplings and are essential components in power transmission systems, helping to transmit torque from one shaft to another while compensating for misalignment and reducing vibration.
Here are some key characteristics and information about flexible disc couplings:
Purpose: Flexible disc couplings are designed to transmit rotary motion between two shafts while accommodating angular, parallel, and axial misalignment. They also help dampen vibrations and shock loads, protecting connected machinery.
Design: These couplings typically consist of two flanged hubs, each connected to a shaft, and a flexible disc or diaphragm that connects the hubs. The disc is usually made of materials like stainless steel or other high-strength alloys.
Flexibility: Flexible disc couplings are designed to be torsionally flexible, allowing for some angular misalignment. The flexibility of the disc helps in minimizing the transmission of vibrations and shock loads between shafts.
Zero Backlash: Many flexible disc couplings offer zero backlash, meaning there is no play or clearance between the connected shafts. This is important in applications where precise motion control is required.
Maintenance: These couplings generally require minimal maintenance, as they don't have many moving parts that can wear out. Regular inspection for wear and proper lubrication, if required, is typically all that's needed.
Applications: Flexible disc couplings are used in a wide range of industries, including manufacturing, power generation, automotive, aerospace, and more. They are commonly found in pumps, compressors, conveyors, and other machinery where torque needs to be transmitted between shafts.
Advantages: Some advantages of flexible disc couplings include their ability to handle misalignment, dampen vibrations, and provide high torque transmission capacity. They are also compact and lightweight.
Disadvantages: These couplings may not be suitable for applications with extreme misalignment requirements, and they may not provide as much flexibility as other coupling types like elastomeric couplings.
In summary, flexible disc couplings are essential components in power transmission systems, offering flexibility, vibration damping, and the ability to accommodate misalignment between shafts. They are widely used in various industrial applications to ensure efficient and reliable machinery operation.

User questions & answers
| Question: | What's the material |
| Answer: | Aluminium alloy and stainless steel. |
| Question: | can I bore the 14 mm end to 19 mm |
| Answer: | As long as you dont interfere with the clamping action! I added a set screw to lock into a flat on the shaft. This is a great unit for stepper motors as it has no backlash and accurately transfers the stepper position to the connected shaft. |
| Question: | Is there enough material on the 8mm side to be bored out to 1/2 of an inch |
| Answer: | Yes, but it should be soft material. |
| Question: | Is this going to be too stiff |
| Answer: | Definitely not! I bought one and i can now travel up and down all 200mm on my MPCNC with no binding. |

Ruland OD16/25-AT Oldham Coupling Disk, Black Acetal, Bore, 1" or 25.4mm OD
Ruland
Product description
Carefully made by Ruland in Marlborough, MA, Oldham couplings are comprised of two hubs pressed fit with either an acetal or nylon disk. Oldham couplings disengage if the disc breaks, acting as a mechanical fuse. Well-suited for handling large amounts of parallel misalignment. Acetal Oldham coupling inserts are zero-backlash and electrically isolating. Maximum is 4,500 RPM. RoHS and Reach compliant. Also called a Oldham coupling insert, disk, or disc.
- Ruland oldham couplings have a zero-backlash balanced design for reduced vibration at speeds up to 4,500 RPM. They can accommodate high amounts of parallel misalignment (up to 10% of the hub OD).
- Acts as a mechanical fuse stopping power transmission during a torque overload. User can combine clamp or set screw hub with inch, metric, keyed, or keyless bore for a high level of customization.
- Made from acetal for higher torque and torsional stiffness capabilities than nylon.
- Proprietary hub machining process for smooth interaction between the hub and disk allowing for significantly longer life.
- Ruland oldham coupling disks are RoHS3 and REACH compliant
