Assembling
7.1 Assembling mod. 0052 to mod. 0270
CAUTION
: It is recommended to use suitable safety equipment during the handling for maintenance because of heavy
and/or bulky parts.
1. Before assembling clean all components preferably with degreaser.
2. Place the pinion ( 2 ) on a support with a square of the same size of the female attachment. Make sure that the pinion is
provided with lower O-ring ( 3 ), spacer ( 4 ) and upper O-ring ( 5 ). Lubricate the O-rings (see arrows fig. 13). The
recommended lubricating grease
is “KLUBER” TRIBO STAR 1EP“
3. Screw down one adjustment screw ( 17 ) with nut ( 16 ) in the right adjustment hole of the cylinder ( 1 ) and let the cam (7)
with ring ( 8 ) slide down on the guiding rail on the cylinder ( 1 ) (see detail. A Fig.14) until it stops against the screw;
4. Lay the cylinder ( 1 ) down on the pinion ( 2 ) holding it with the NAMUR surface rotated by approx. 50° to the upper slot
of the pinion, see fig. 15 ;
5. Fit on the pinion ( 2 ) the O-ring ( 6 ), the spacer ( 9 ), the washer ( 10 ), the snap ring ( 11 ), see Fig. 16 ;
6. Grease the internal chamber of the cylinder ( 1 ) and both pistons ( 12 ) provided with O-ring ( 13 ) antifriction ring ( 14 )
and thrust block ( 15 ) The recommended lubricating grease
is “KLUBER” TRIBO STAR 1EP“.
7. For the standard execution (clockwise rotation opens) press the pistons ( 12 ) into the cylinder ( 1 ) while turning the
cylinder ( 1 ) in counterclockwise direction ( top view) until the pistons come into contact, see fig. 17 ;
8. Screw down the second adjustment screw ( 17 ) with nut ( 16 ) in the cylinder (1) and adjust the travel stop, paragraph 8;
9. For DOUBLE ACTING ACTUATOR: Mount the end cap ( 21-22 ) with O-ring ( 24 ) and gasket ( 23 ) on the cylinder and
screw down in crossed sequence the screws ( 25 ), see fig. 18. Repeat the operation on the opposite side.
For SPRING RETURN ACTUATOR: Introduce the spring set ( 18-19-20 ) into the cylinder ( 1 ) and center them on the piston
( 12 ), then mount the caps ( 21-22 ) with O-ring ( 24 ) and gaskets ( 23 ) centered on the springs ( 18-19-20 ). Note: the
pistons have to be in CLOSED position. Screw partially down the screws ( 25 ) in crossed sequence compressing the springs
uniformly until the cap is completely closed, see fig. 18. Repeat the operation on the opposite side;
10. Execute some test cycles to check the correct functioning of the actuator before installing it.
