Q: Can a bellows coupling be too stiff for an application? A: Stiffness should never be avoided — only misalignment. However, this gets back to the misalignmentcompensation issue. Bellows ...

The Model BKC compact bellows coupling features a stainless-steel bellows for high torsional rigidity with zero backlash and flexibility across all three axes of shaft misalignment ...

This looked promising, but reversing the flow proved difficult. After building his own set of water valves to change the flow direction, the bellows began to work slowly, but with limited performance.

Stainless-steel bellows couplings have the highesttorsional stiffness of commercially available flexible couplings, making themthe best choice for aggressive servo-driven applications.

Backlash-free metal bellows couplings have long been available from Rino Industries Ltd, the precision engineered components specialist based in Chesterfield, but there is now a pluggable version too.

The firm’s bellows-free solution brings together creative design, smart materials selection and precision operation. Now that the linear drive is in its final prototype phase, the team is working ...
