Insert the piston with the coupling attached and the threaded sealing band •
all the way into the cylinder barrel so that the sealing band inserts into the
slot in the cylinder barrel.
Note
When inserting the piston, make sure that the magnetic side of the piston is
opposite the cut-outs on the groove for the proximity switches in the cylinder
barrel.
In order to fasten the sealing band in place in the sealing band holder, move •
the piston once to the other end of the cylinder barrel and hold the sealing
band in place with pliers as you do so.
Note
The sealing band is pulled into the cylinder barrel by the draw of the piston.
Make sure that the sealing band protrudes 4 mm from the cylinder barrel.
Note
The sealing band must not protrude beyond the buffer, otherwise the end
cap cannot form an air-tight seal and may have an adverse effect on the
function of the linear drive. The sealing band must be shortened so that it
seals off flush with the outer edge of the buffers. However, it is better if it is
slightly short of the buffers.
Attach the buffers to both ends of the cylinder barrel. •
Grease one new sealing ring per buffer and insert them in the buffers. •
Attach the clips to the buffers to fasten the sealing band in place. •
Apply Loctite 243 to the self-tapping screws. •
Attach the end caps to both ends of the cylinder barrel. •
Screw the self-tapping screws into the cylinder barrel through the end cap •
and attach them loosely so that the end caps can still be shifted.
Align the rear and bottom edge of both end caps flush with the cylinder •
barrel.
Tighten the self-tapping screws on both ends using the appropriate torque
•
(see table).
