7-4. Special instructions
･
HA type (M09 size is RA)
○
Do not use coolant. Failure to follow this instruction results in breakdown.
○
For the air piping, use a 3-point unit, and be sure to use oil mist.
○
Do not operate the cylinder without air.
○
The air pressure shall be 1.0MPa(10.2kgf/cm
2
) or less.
○
Normally, the Teflon seal withstands 5,000 hours of operation. (However, it varies
depending on the lubrication and the working pressure.) Therefore, it needs to be
replaced when the following phenomena are observed.
If the volume of oil mist increases on the air circuit side, contamination of hydraulic oil
may because of wear in or damage to the Teflon seal.
To check wear, follow the procedure below. (See 1-4 HA type (M09 size is RA) parts list
on pages 7-8 and 7-3 HA type (M09 size is RA) List of seals to use on pages 28.)
When removing the parts, place a match mark(s) on each part for reassembly.
(1) Remove the socket head cap screw [19](4 pieces) to remove the sleeve cover [7]
and the shim ring [12].
(2) Check that the rear end of the rotary valve [4] dose not get wet with oil.
Note) If it gets wet with oil, replace the Teflon seal [34] because it is worn or damaged.
(3) Check the Teflon seal [34] in the center of the sleeve cover [7] for wear. If it
becomes deformed, worn on one side, etc., replace it.
To facilitate assembly at the joint and the seal part, or prevent flaws in assembling
the seal, apply a sufficient amount of oil (equivalent to turbine oil #90) or of grease
(general grease: Class 1) to follow the disassembly procedure in the reverse order
with due care so as not to damage the bearing, the o-ring, and the Teflon seal.
Tighten the socket head cap screw with the specified tightening torque (M6:13N
･
m).

HB type
○
Before rotation, supply about 10cc of oil (equivalent to turbine oil #90) from the E port on
the top of the sleeve cover. Failure to follow this instruction may result in damage to the
mechanical seal.
○
Do not use air. Failure to follow this instruction results in breakdown.
○
Be sure to keep coolant running during rotation.
○
Be sure to install piping to the coolant drain port (C-Dr port). Use a transparent vinyl
hose, and return it to the coolant level in the coolant tank. Although coolant is not
discharged from the coolant drain port in a normal state, it leaks from this port if the
mechanical seal is worn or damaged. For this reason, use a transparent hose for easy
checking.
○
Normally, the mechanical seal withstands 8,000 hours or more of operation. However,
