Bellows coupling BKXK 1622/1624/1627: 16 mm diameter, 22-27 mm length

The BKXK 1622, BKXK 1624 and BKXK 1627 bellows couplings are the smallest versions in our product portfolio. The shaft couplings with stainless steel bellows and aluminium clamping hubs can be used on both ground and unmachined shafts. The designation numbers provide information about the installation dimensions: the diameter of 16 mm is at the front, the overall lengths are 22, 24 or 27 mm. Their performance data varies slightly accordingly. You can find examples of applications under "Bellows couplings".
Compare this with other BKXK variants in slightly larger versions: BKXK 2129/2135, BKXK 2429/2435, BKXK 2530/2535, BKXK 3030/3035 as well as BKXK 3340 and BKXK 4048.
