Helical couplings WKAK 2532 and WKAK 3038: The largest standard couplings in the helical coupling portfolio

The WKAK 2532/3038 are the largest helical couplings made of aluminium with clamping hubs in our range. The article designation implicitly indicates the sizes: with a diameter of 25 or 30 mm, the installation lengths are 32 or 38 mm. The high moments of inertia should be emphasised here. We will be happy to provide you with specific advice on which of our couplings is suitable for you: anfrage@abp-antrieb.de

Also compare our screw versions WKAS 2532, WKAS 3030 and WKAS 3038 for use at higher speeds.

Or perhaps our stainless steel versions WKXS 2524 or WKXK 2532 are the right choice for you.
