Mann Teknik AB delivers breaking pins according to customer specication. Standard
pins are available for different applications. The breaking force should be specied for the
weakest component
Without any specication we supply our couplings with bolts according to the following
table.
Table 4: Internal pressure reduces the force needed to release the coupling.
