FSKK 2519 and FSKK 2525 spring disc couplings with 25 mm diameter
The FSKK 2519 and FSKK 2525 spring disc couplings from abp are comparatively powerful, yet inexpensive shaft couplings with a plastic centre section. The name provides information about the sizes: the diameter of 25 mm with installation lengths of 19 or 25 mm is at the front. Clamping hubs provide more flexibility during installation. The FSKK variants are electrically insulating and pluggable thanks to their plastic centre section.
Compare our variants with FSXS screw hubs and FSXK steel centre section.
