Rigid Couplings GN 2260

Material: ST - Steel
Bore code: B - Without keyway

Product Family Stainless Steel Quality Class 1

The Ganter product range includes a large number of standard parts made of high-quality, non-rusting stainless steels. Thanks to their outstanding material properties, these are used in a wide array of industries. Their corrosion and rust resistance in particular contributes to the value stability and longevity of machines and equipment.

For easier differentiation, the stainless steels used by Ganter are divided into stainless steel quality classes:

Stainless Steel Quality Class 1

Stainless Steel Quality Class 2

Stainless Steel Quality Class 4

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.
