Bellows couplings BKXS 2029/2035: 20mm diameter &29/35mm length

The BKXS 2029 and BKXS2035 bellows couplings are part of the BKXS range with stainless steel bellows and aluminium hubs. The diameter here is 20 mm, the overall lengths are available in 29 or 35 mm. The performance data of the variants vary slightly depending on their size. Compared to the smaller versions in our programme, the performance values here make a considerable leap. Ideal when higher power reserves are required. You will find a wide range of application examples under the heading Bellows couplings.

Compare other identical BKXS variants with different sizes and performance values.
