Helical couplings WKAK 1215 and WKAK 1421, our smallest sizes with clamping hubs
The abp WKAK 1215 and WKAK 1421 are the smallest helical couplings with clamping hubs in stock: small outer diameters of 12 and 14 mm and small sizes of 15 and 21 mm. The aluminium compensating coupling is made from one piece.
The outstanding radial spring stiffness of the WKAK 1215 should be emphasised for this size. Please also compare the data of the next larger variants WKAK 1625 and WKAK 1928.
