Nickel bellows couplings with screw hubs

The BKNS range of nickel bellows couplings are versions with stress-free nickel bellows for applications where high precision is required. They enable play‑free and angularly accurate transmission of rotary movements and optimally compensate for misalignment. The designation numbers provide information about the installation dimensions: the diameter of 12, 17 or 25 mm is shown at the front. The installation lengths behind are 23, 30 or 33 mm and can therefore be optimally adapted to your application. Their technical data depends on the size, but the nickel bellows couplings from abp all have very high torsional rigidity combined with low restoring forces. These properties are ideal for measuring tasks. The BKNS 1223 variant is also characterized by inox steel hubs.
