5. Since Series CHKDB does not have an air release plug, release air from other components (e.g. from piping, etc.) as well.

6. Do not use two cylinders facing one another horizontally or vertically in such a way that their piston rods strike each other.

7. When the cylinder head side contains hydraulic fluid or is in a normally pressurized condition, the applied load must not be allowed to strike the piston rod end. Avoid such applications.

8. When mounting the cylinder body with mounting bolts, use tightening torques in the table at left as a guide.

Magnetic body (steel plate, etc.)

A special scraper is installed on the basic cylinder to prevent liquid in the surrounding area from entering the cylinder.It can be used in environments where exposure to machine tool coolants is likely, as well as in environments where water spray and splashing is frequent, such as in food processing machinery and car washing equipment.

Be sure to read before handling. Refer to pages 135 through 141 for safety instructions, hydraulic cylinder precautions and auto switch precautions.

2.547

16304070

Consult with SMC when using a cylinder in close proximity to a magnetic body (including proximity on any side) as shown in the figure below, as the operation of auto switches may become unstable.

Series CHKDB

1. Use hexagon socket head cap screws (JISB1176, strength class 10.9 or higher) for cylinder mounting.

2. Since a lateral load (eccentric load) cannot be applied to the piston rod, build the mounting jig in such a way that a lateral load will not be applied to the piston rod.

3. Make sure that the interlocking length of the rod end thread (male or female thread) and the mounting material is at least 80% of the thread diameter.

4. When operating a cylinder for the first time, be sure to release the air inside the cylinder and the piping. When the air release is complete, operate the cylinder at reduced pressure, then gradually increase it to the normal operating pressure.

Note) For all dimensions other than the above, please refer to page 7.

Caution

M2.5 x 4l(included with auto switch)

When mounting auto switches, they should be inserted into the cylinder's switch mounting groove from the direction shown in the drawing below. After setting in the mounting position, use a flat head watchmakers screw driver to tighten the set screw that is included.

When tightening the auto switch mounting screw, use a watchmakers screw driver with a handle about 5 to 6mm in diameter.Also, tighten with a torque of 0.1 to 0.2Nm for types D-A9 and D-F9, and 0.05 to 0.1Nm for types D-Z7, D-Z8, D-Y5, D-Y6 and D-Y7. As a rule, the mounting screw should be turned about 90 past the point at which tightening can first be felt.

1. Use hexagon socket head cap screws (JISB1176, strength class 10.9 or higher) for cylinder mounting.



4. When operating a cylinder for the first time, be sure to relase the air inside the cylinder and the piping. When the air release is complete, operate the cylinder at reduced pressure, then gradually increase it to the normal operating pressure.

5. Since Series CHKGB does not have an air release plug, release air from other components (e.g. from piping, etc.) as well.



8. When mounting the cylinder body with mounting bolts, use tightening torques in the table at left as a guide.

Auto Switch Mounting

When mounting auto switches, they should first be set into the mounting bracket and inserted into the cylinder's switch mounting groove from the direction shown in the drawing below. After setting in the mounting position, use a hexagon wrench to tighten the switch mounting bracket screw that is included.

When tightening the auto switch mounting screw, use a watchmakers screw driver with a handle about 5 to 6 mm in diameter. When tightening the mounting bracket screw, use a 1.5mm hexagon wrench. The tightening torque should be approximately 0.1 to 0.2Nm for types D-A9 and D-F9, and 0.05 to 0.1Nm for types D-Z7, D-Z8, D-Y5, D-Y6 and D-Y7. As a rule, the mounting screw should be turned about 90 past the point at which tightening can first be felt.

Caution1. Use hexagon socket head cap

screws (JISB1176, strength class 10.9 or higher) for cylinder mounting. (20: 2 pcs.; 32 to 100: 4 pcs.)



4. When operating a cylinder for the first time, be sure to release the air inside the cylinder and the piping. When the air release is complete, operate the cylinder at reduced pressure, then gradually increase it to the normal operating pressure.

5. Since Series CHQB does not have an air release plug, release air from other components (e.g. from piping, etc.) as well.

6. When mounting the cylinder body with mounting bolts, use the tightening torques in the table at right as a guide.

7. Do not use two cylinders facing one another horizontally or verti-cally in such a way that their piston rods strike each other.

Caution1. Use hexagon socket head cap

screws (JISB1176, strength class 10.9 or higher) for cylinder mounting. (20: 2pcs, 32 to 100: 4pcs.)

2. Since a lateral load (eccentric load) cannot be applied to the piston rod, build your mounting jig in such a way that a lateral load will not be applied to the piston rod.

3. Make sure that the interlocking length of the rod end threads (male or female thread) and the mounting material is at least 80% of the thread diameter.

4. Be sure to release the air inside the cylinder and the piping before operating the cylinder for the first time. When the air release is complete, operate the cylinder at reduced pressure, then gradually increase it to the normal operating pressure.

5. Since Series CHQWB does not have an air release plug, release air from components other than the cylinder (e.g. from piping, etc.) as well.

6. When mounting the cylinder body with mounting bolts, use tightening torques in the table below as a guide.

7. When tightening the piston rod end threads, be sure to use the wrench flats of the rod on the side where the threads are being tightened. Use care, as damage may occur if rotational force is applied to both ends of the piston rod.


9. When the cylinder head contains fluid or is in a normally pressurized condition, the load should not be allowed to strike the piston rod end. Avoid such applications.

Usage

Be sure to read before handling. Refer to pages 135 through 141 for safety instructions, hydraulic cylinder precautions, and auto switch precautions.

[Stainless Steel Mounting Screw Kit]The following stainless steel mounting screw kit (including nuts) is available to meet special operating environment conditions. (Please note that auto switch mounting bands are not included and must be ordered separately.)

Stainless steel mounting screw kit: BBA3 for D-B5, D-B6, D-G5, and D-K5Stainless steel mounting screw kit: BBA4 for D-C7, D-C8, and D-H7

When the type D-H7BAL switch is shipped already mounted on a cylinder, the above stainless steel screws are used. When the same switch is ordered separately, BBA4 screw kit is automatically included with the switches.

Minimum Strokes for Auto Switch MountingSpecific Product Precautions

Caution1. Since Series CHM does not have an

air release valve, release air from components other than the cylinder (e.g. from piping, etc.).

2. When operating a cylinder for the first time, be sure to release the air at low pressure. When the air release is complete, operate the cylinder at reduced pressure, then gradually increase it to the normal operating pressure. However, the piston speed at this time should be adjusted to the minimum speed.

1. When mounting with bracket mounting nuts, tighten them using the tightening torques in the table below as a guide.

2. When mounted with one side attached and one side free (basic type, flange type) and operating at high speed, the bending moment acts on the cylinder due to oscillation at the stroke end, which may cause cylinder damage. In this type of situation, install brackets to suppress the oscillation of the cylinder body, or reduce the piston speed enough so that the cylinder body does not
