Product description

Rigid couplings GN 2260 connect supported shafts or are used as couplings for shaft extensions. They transmit angular positions and high torques precisely and with zero backlash, without compensating for alignment errors and runout tolerances. The slotted design makes them very easy to install.

With the bore code K, the keyway is always integrated into both bores d₂ and d₃. For applications with strong vibrations, thread locking is recommended for the clamping screws.
