Product description

Rigid couplings GN 2264 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. Due to their split design, they can be used where axial mounting is not possible.

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.
