Bellows couplings BKXS 2526/2531: 25mm diameter & 26/31mm length
The bellows couplings BKXS 2526 and BKXS 2031 are variants with stainless steel bellows and aluminium hubs and fastening with grub screw. The diameter is 25 mm, the overall lengths are available in 26 mm and 31 mm. The performance data of the variants vary slightly depending on their size. The comparatively high torsion spring stiffness should be emphasised here. Detailed application examples can be found under the heading bellows couplings.
Depending on the application, compare identical BKXS variants with smaller diameters, overall lengths and other performance values.
