Heavy-duty aluminium helix couplings W3AK 1923, W3AK 2532 and W3AK 3245: from 23mm to 45mm in length

abp also offers a wide range of sizes in its programme for heavy-duty couplings. This has the advantage that most of the required performance parameters can be met with our standard programme. The W3AK heavy-duty helix couplings 1923, 2532 and 3245 are the larger of our compensating couplings in the heavy-duty range and therefore offer higher performance parameters.

Also compare the smaller variants W3AK 1923/2532/3245 or the normal helix couplings.

We also offer stainless steel versions for applications in harsh environments: the W3XK 2532 and the W6XK 2538.
