Hydrostatic bearing actuator has no sealing gaskets. With
the help pf special designed hydrostatic bearing unit, the
piston rod automatically regulates itself that ensures
constantly alignment between piston rod and cylinder
housing and central guiding.
While bearings center the piston, all sliding surfaces in
actuator are separated by oil film under pressure; this oil
film in hydrostatic bearings exists before piston moves and
is maintained even under lateral force so to exclude friction
& wear.
Hydrostatic bearing actuator offers much high
performance and fits in well with testing tasks where high
accuracy of control and measurement is essentially
desired.
