HA-CO Plug-in Oldham Couplings
Compact and backlash-free couplings for precision drive systems
When installation space is limited, a compact and easy-to-install shaft coupling can provide an effective solution. HA-CO plug-in Oldham couplings are designed for applications where space saving, precise torque transmission and flexibility are important.
These high-quality Oldham couplings feature a compact three-piece construction and can be easily plugged together. This makes them particularly suitable for precision systems and drive applications where simple installation and limited installation space are important.
The combination of low weight, high torsional stiffness and backlash-free operation provides a reliable solution for a wide range of industrial and precision applications.
What is a HA-CO plug-in Oldham coupling?
An Oldham coupling is a mechanical shaft coupling used to connect two shafts. The coupling consists of three separate components that work together to provide reliable torque transmission.
The construction consists of two hub sections and a central disc or sliding element. The central element forms the connection between the two hubs and allows controlled movement.
An important advantage of the Oldham design is its ability to compensate for small alignment errors between the two shafts.
The coupling can compensate for:
Radial or parallel shaft misalignment.
Small angular deviations.
Axial movement, depending on the version.
Assembly and manufacturing deviations.
This creates a flexible connection without requiring a large coupling.

The special construction of an Oldham coupling
An important feature of the Oldham coupling is its three-piece construction.
The two hub sections are mounted on the respective shafts. A central sliding element is positioned between the hubs. The specific design allows the individual components to move relative to one another.
This allows the coupling to compensate for small misalignments between the shafts without creating a completely rigid connection between the drive components.
At the same time, the construction provides reliable torque transmission.
This combination makes the Oldham coupling particularly suitable for compact and precise drive systems.
Compensation of shaft misalignment
When designing machines, it is not always possible to align two shafts perfectly. Small deviations can occur due to assembly, manufacturing tolerances or movement during machine operation.
If these deviations are not compensated, additional forces can be generated on shafts, bearings and other drive components.
The Oldham coupling can compensate for small parallel and other permissible alignment errors. This allows the coupling to create a flexible connection between two shafts.
This makes the coupling suitable for applications where both a compact construction and a certain degree of flexibility are required.
Backlash-free torque transmission
An important advantage of a HA-CO plug-in Oldham coupling is its backlash-free operation.
In precision systems, unwanted play can result in inaccuracies in movement and positioning. For this reason, accurate and direct torque transmission is important.
The Oldham coupling is designed to transmit torque reliably and accurately between the two shafts.
This makes the coupling suitable for systems where a high level of precision is required.
High torsional stiffness and low weight
In addition to its compact construction, the Oldham coupling offers a combination of high torsional stiffness and low weight.
High torsional stiffness allows the coupling to transmit movement and changes in torque accurately. At the same time, low weight results in relatively low mass inertia, which can be important in dynamic drive systems.
These characteristics make the coupling suitable for systems where fast and precise movement is required.
Easy plug-in installation
One of the key features of this version is its simple plug-in installation.
The three-piece construction allows the coupling to be easily assembled and separated. This can simplify installation and maintenance of the drive system.
This is particularly useful in machines where components need to be replaced regularly or where space around the coupling is limited.
The simple installation also makes the coupling suitable for compact machine designs.
Space-saving solution
In modern machines, available installation space is becoming increasingly important. Drive components therefore often need to be designed as compactly as possible.
The HA-CO plug-in Oldham coupling is designed with compact installation in mind. This allows the coupling to be used in locations where larger couplings would be difficult or impossible to integrate.
The combination of small dimensions, low weight and reliable torque transmission makes this coupling suitable for compact precision systems.
Suitable for precision applications
Thanks to its backlash-free operation, high torsional stiffness and compact construction, the Oldham coupling can be used in a wide range of precision applications.
It is particularly suitable for systems where accurate transmission of movement and position is important.
