Bellows coupling                                  BKXK 3030/3035: 30mm diameter& 30/35mm length

The BKXK 2530 and BKXK 2535 bellows couplings are available with stainless steel bellows and aluminium clamping hubs.
With a diameter of 30 mm, overall lengths of 30 or 35 mm are available. The torsion spring stiffness reaches values of up to 240 Nm. We offer other diameters and lengths in our other BKXK variants. Examples of applications are listed on the "Bellows couplings" page.
