Rigid coupling GN 2262

aluminumfor shaftshigh-speed

Product description
Rigid couplings GN 2262 connect supported shafts or serve as couplings for shaft extensions. They transmit angular positions precisely and without backlash at high rotational speeds. These couplings do not compensate for alignment errors or runout tolerances. The slotted design enables straightforward installation.

Key functional note
With bore code K the keyway is integrated into both bores d2 and d3.
