Helical coupling WKAS 6508, WKAS1015 and WKAS 1218 - the smallest sizes in the portfolio

The WKAS spiral couplings from abp are our smallest couplings in the spiral coupling range: the outer diameters are between 6.5mm and 12mm with overall lengths of 8, 15 and 18 mm. The all-metal compensating couplings are made of aluminium. Despite their small size, they have a vibration-damping effect and optimally compensate for misalignments. They are attached using screws.
