Rigid coupling GN 2260

stainless steelsteelfor mechanical power transmission

Overview
Rigid couplings GN 2260 connect supported shafts or are used as couplings for shaft extensions. They transmit angular position and high torque precisely and with zero backlash. The slotted design enables straightforward assembly. These couplings do not compensate for shaft misalignment or runout tolerances.

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