The fvourle re rtio (piston/piston rod) llows high clmping forces lredy t reltively low oil pressures. Due to the sturdy swing mechnism the ngle position of the clmping rm remins the sme fter slight collision with the workpiece during loding or unloding. lso collision during the clmping process is not criticl. When using high flow rtes the swing speed is limited y instlled throttle points. The FKM wiper t the piston rod cn e protected ginst corse nd hot swrf y n optionlly ville metllic wiper (see pge ).

In the effective re of piston rod nd clmping rm there is the dnger of crushing. The mnufcturer of the fixture or the mchine is oliged to provide effective protection devices. The swing clmp hs no overlod protection device. When mounting the clmping rm, the clmping rm or the hexgon socket in the piston hve to e cked up for tightening nd untightening the fixing nut.
