Product Picture
These stainless steel shaft couplers allow you to couple 2 size shafts together. They can be used for connecting motor shafts to drive shafts, or 2 different-sized shafts. These shaft couplers have a length of 0.75″, a outer diameter of 0.42″, and couple 1/4″ to 5mm shafts.
Connect this to that with a set-screw coupler. These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be fit to 2 shafts even if they are not perfectly co-linear and will help reduce binding effects.
This coupler will connect a 5mm diameter shaft to an 8mm diameter shaft. A perfect add on for motors. Comes with 2 sets of double set-screws (two per side) for secure attachment. You’ll need a 2mm allen wrench to tighten/loosen the set-screws.

Can Sleeve Couplings Accommodate Axial and Angular Misalignments Simultaneously?
Yes, sleeve couplings are designed to accommodate both axial and angular misalignments simultaneously. They offer a certain degree of flexibility, allowing them to compensate for minor misalignments between the shafts they connect. Here’s how sleeve couplings handle axial and angular misalignments:
1. Axial Misalignment:
Axial misalignment refers to the misalignment that occurs along the axis of the connected shafts. In other words, one shaft is slightly offset from the other along their common centerline. Sleeve couplings can tolerate a small amount of axial misalignment because of their flexible nature.
When axial misalignment occurs, the sleeve coupling can flex along its length, allowing the shafts to remain connected despite the slight offset. The coupling’s flexibility prevents excessive stress on the connected machinery and helps maintain a smooth torque transmission.
2. Angular Misalignment:
Angular misalignment, on the other hand, occurs when the two shafts are not perfectly aligned in the same plane. Instead, they form an angle with each other. Sleeve couplings can also accommodate a certain amount of angular misalignment.
When angular misalignment is present, the sleeve coupling can bend and twist slightly to compensate for the angle between the shafts. This ability to flex and twist ensures that the coupling can transmit torque efficiently and reduces the risk of premature wear or damage to the system.
Simultaneous Axial and Angular Misalignment:
Sleeve couplings are well-suited to handle both axial and angular misalignments simultaneously. When a system experiences both types of misalignments, the sleeve coupling’s flexibility allows it to adjust and compensate for both the axial offset and angular deviation between the shafts.
It is important to note that while sleeve couplings can handle some misalignments, excessive misalignments should be avoided to prevent excessive wear and premature failure of the coupling. Regular inspections and maintenance can help ensure that the coupling operates within its designed misalignment limits and maintains optimal performance in the motion control system.
In summary, sleeve couplings can simultaneously accommodate both axial and angular misalignments to a certain extent due to their flexible and forgiving design. However, it is essential to ensure that the system is well-aligned and that the coupling is regularly inspected to ensure it functions correctly and provides reliable power transmission in various industrial applications.
What are the Standard Sizes and Dimensions Available for Sleeve Couplings?
Sleeve couplings are available in a wide range of standard sizes and dimensions to accommodate various shaft diameters and application requirements. The dimensions of sleeve couplings depend on factors such as the shaft size, coupling length, and overall design. Here are some common standard sizes and dimensions for sleeve couplings:
Shaft Sizes: Sleeve couplings are typically designed to fit specific shaft diameters, commonly ranging from a few millimeters to several inches. Standard sizes may include shaft diameters of 6 mm, 8 mm, 10 mm, 12 mm, 15 mm, 20 mm, 25 mm, 30 mm, 40 mm, 50 mm, and so on.
Coupling Length: The length of the coupling refers to the distance between the two ends that connect the shafts. The coupling length is usually determined by the application’s torque and space requirements.
Overall Diameter: The overall diameter of the sleeve coupling varies with the shaft size and coupling design. It is important to ensure that the overall diameter of the coupling fits within the available space and does not interfere with other components in the system.
Keyway Size: Some sleeve couplings feature keyways to provide additional torque transmission and anti-rotation capabilities. The keyway size should match the shaft’s keyway dimensions to ensure a secure connection.
Material Thickness: The thickness of the sleeve coupling’s material is critical for its strength and torque capacity. Standard sleeve couplings are available in various material thicknesses to suit different application requirements.
It’s important to note that while standard sizes and dimensions are readily available, custom sleeve couplings can also be designed and manufactured to meet specific application needs. Custom couplings may be required for non-standard shaft sizes, special torque capacities, or unique environmental conditions.
When selecting a sleeve coupling, engineers should consider the torque requirements, shaft sizes, space limitations, and environmental factors to ensure the coupling’s proper fit and reliable performance.
What is a Sleeve Coupling, and How is it Used in Mechanical Power Transmission?
A sleeve coupling is a type of flexible coupling used in mechanical power transmission to connect two shafts and transmit torque between them. It consists of a hollow cylindrical sleeve with an inner diameter that matches the shafts’ outer diameters. The sleeve coupling is placed over the ends of the shafts, and its flexibility allows for some misalignment between the shafts while transmitting rotational power from one shaft to the other.
The sleeve coupling is a simple and cost-effective coupling solution commonly used in various industrial applications. Its design allows for easy installation and maintenance, making it suitable for applications where frequent shaft disconnection and reconnection are required.
Here’s how a sleeve coupling works in mechanical power transmission:
- Shaft Connection:
The sleeve coupling connects two shafts that need to be linked together to transmit power.
- Flexible Design:
The flexibility of the sleeve coupling allows for some angular and axial misalignment between the shafts. This flexibility is achieved due to the clearance between the inner diameter of the sleeve and the outer diameter of the shafts.
- Torque Transmission:
When one shaft rotates, it transfers torque to the sleeve coupling. The flexible nature of the coupling allows it to compensate for minor misalignments and still transmit torque smoothly to the other shaft.
- Reduced Vibration and Shock Absorption:
The flexibility of the sleeve coupling also helps dampen vibrations and absorb shocks, preventing them from transferring between the connected shafts. This feature contributes to the smooth and efficient operation of the connected machinery.
- Limitations:
Sleeve couplings have their limitations, including lower torsional stiffness compared to other coupling types, which may limit their use in precision applications with high torque and speed requirements. Additionally, sleeve couplings are not suitable for applications with significant misalignments or when precise angular alignment is crucial.
In summary, a sleeve coupling is a flexible and straightforward coupling used in mechanical power transmission to connect two shafts while allowing for some misalignment. Its simple design and ability to absorb shocks and dampen vibrations make it a popular choice for various industrial applications where precision alignment is not critical.
