Cylinders with Integrated Guide
Series QCT and QCB
Double-acting, magnetic piston, guided
ø 20, 25, 32, 40, 50, 63
These compact cylinders, designed to be used in applications where space is limited, are
available in two versions: one with sintered bronze bushes (model QCT) and the other
with linear ball bearings (model QCB). The QCT version would normally be selected when
the side loads applied to the cylinder are high. Model QCB cylinders are suitable for high
precision and fast cycling applications.
Both models are equipped with fixed
cushioning to prevent direct impact with the
end covers. The design of the cylinder body
allows the mounting of the cylinder using
either top, bottom or side faces. Several “T”
shaped grooves in two faces allow sensors
to be fitted in a number of positions.
Non-standard strokes are available on
demand only.
