## Summary description

Fixed aluminium coupling with 5x8 mm bore size, OEM part AMS-18933. Designed to join shafts or rods with a 5 mm input and 8 mm output diameter in mechanical assemblies. Solid (non-adjustable) design provides rigid connection for torque transmission in robotics, small machinery, model building and industrial prototypes.

## Long description

Fixed Aluminum Coupling 5x8 mm is a solid, non-adjustable shaft connector designed to join a 5 mm input shaft to an 8 mm output shaft. Machined from aluminum, this rigid coupling ensures direct torque transmission between two misaligned-diameter shafts in compact mechanical assemblies. Its fixed geometry makes it suitable where angular or axial flexibility is not required and where a secure, stable connection is preferred for repeatable motion transfer.
Advantages
The coupling’s aluminum construction offers a balance of light weight and sufficient strength for small to medium torque applications. Its fixed design eliminates backlash and slop associated with adjustable joints, delivering a consistent mechanical link. Machined bore sizes for 5 mm and 8 mm shafts simplify installation without the need for adapters, reducing assembly time in robotics, model building, and prototype equipment.
Suitable for
Connecting a 5 mm drive shaft to an 8 mm driven shaft in small machinery
Robotics joints and actuator linkages requiring rigid torque transfer
Model building and hobbyist mechanical assemblies
Prototype and test rigs where a non-flexible coupling is acceptable
Key specifications
Material: aluminum
Type: fixed (non-adjustable) coupling
Bore sizes: 5 mm (input) and 8 mm (output)
Intended connection: solid shaft-to-shaft coupling for torque transmission
Typical applications: robotics, small machinery, model building, prototypes
How to use
Align the 5 mm and 8 mm shafts with the respective bores and slide the coupling onto the shafts until it seats fully. Ensure shafts are clean and free of burrs before assembly. Secure the coupling according to the manufacturer’s recommended method for fixed couplings (for example, set screws or press fit) suitable for your shafts and operating conditions. Verify alignment and secure fit before applying operational torque.
Usage recommendations
Use this fixed aluminum coupling where a rigid connection is needed and shaft misalignment is minimal. Avoid applications with high misalignment, frequent angular movement, or heavy shock loads; in those cases, consider flexible or compliant coupling alternatives. Regularly inspect for wear and ensure set screws or fastening methods remain tight during routine maintenance.
