BK1
Bellows couplingsWith its compact design, the BK1 bellows coupling from R+W Couplings is very suitable for installation in small spaces and special applications. Due to the simple bolt connection, the BK1 is completely clearance-free. The design of this precision clutch results in high torsional rigidity and quiet running due to symmetrical force distribution. The design of this precision clutch results in high torsional rigidity and quiet running due to symmetrical force distribution. As long as they do not fall outside the maximum area, no metal fatigue will occur in the bellows material and the clutch is completely free of wear.
