Fields of application:
Bush diameters: ø4 to ø30mm with wall thicknesses of 0.3 to 1.0 mm
Bush materials: teflon-coated sheet-metal bushes or bushes with fabric backing,
connectors with/without counter-washer
Bushing unit types and sizes:
4 preferably used model ranges exist:
Hydropneumatic feed unit up to 15 kN at a stroke of 100/12 mm
Hydropneumatic feed unit up to 30 kN at a stroke of 100/30 mm
Electric servo feed unit up to 30 kN at a stroke of 300 mm max.
Electric servo feed unit up to 60 kN at a stroke of 250 mm max.
The Friedrich bushing units can, of course, be combined with electronic quality assurance systems. To this effect various controls and programmes are available which are based on pressure versus displacement measurements and matched to the special conditions of bushing.
