Reely tuhá hriadeľová spojka pre 6 mm hriadeľ, vonkajší priemer 30 mm, hliník, strieborná (RE-8660205)

This rigid shaft coupling from Reely offers a direct, backlash-free connection for 6 mm shafts in model building and robotics. Unlike flexible couplings, it maintains precise alignment and transmits torque without angular or axial play, making it ideal for applications where positional accuracy is critical. The coupling is machined from aluminum with a silver finish, providing corrosion resistance and a lightweight yet robust solution. Its 30 mm outer diameter and 25 mm length suit compact drive systems, and the set screw mounting ensures a secure grip on the shaft. Whether you are building a CNC machine, a robot arm, or an RC model, this coupling delivers reliable performance.

Highlights

• Rigid design ensures zero backlash and high torsional stiffness
• Compatible with 6 mm diameter shafts
• Aluminum construction offers strength with low weight
• Set screw mounting for easy installation and secure hold
• Corrosion-resistant silver finish

In daily use

Installation is straightforward: slide the coupling onto the shaft ends and tighten the set screws. The rigid connection maintains exact shaft alignment, which is essential for precision mechanisms. The aluminum body dissipates heat well and withstands typical hobbyist and light industrial operating temperatures. With a length of 25 mm, it fits into tight spaces without compromising shaft engagement.
