Heavy-duty Helix coupling W3AK 1014, W3AK 1319 and W3AK 1620: 3-helical equalising couplings

With their small installation dimensions, the W3AK 1014, W3AK 1319 and W3AK 1620 heavy-duty Helix couplings from abp are ideal for maximising power transmission in the smallest of spaces. As with all our clutches, the parameters can be read directly from the designation. The 3 after the "W" stands for the number of coils, the first two numbers indicate the diameters of 10, 13 and 16 mm, the last two the installation lengths of 14, 19 and 20 mm. The aluminium compensating couplings are made from one piece and are fastened with clamping hubs.

Compare with the larger variants W3AK 1923/2532/3245.
