
If an O-ring is caught by the mounting surface,
it could cause leakage of the lubricant.

If there is foreign matter adhering to the
mounting surface, the mounting surface of the
reduction gear may be deformed, which could
cause deterioration of performance, such as
abnormal noise and torque irregularity, and
durability.

The shape of the shaft installation component
may differ from the illustration above,
depending on the customer’s equipment or
shape of the reduction gear.
 When sealing with a liquid sealant

When sealing the section with a liquid sealant, coat
the liquid sealant onto the
area at the shaft
mounting surface. For the coating area, refer to the
illustration on the right.

Apply coating seamlessly in the coating area.

Take extra care so that the liquid sealant will not
leak into the reduction gear or mounting bolt
section.

For the pin/bolt clamping output shaft type (20E,
40E), apply the liquid sealant around the mounting
hole.

For the detailed coating procedure, follow the
instructions given by the manufacturer of the
sealant to be used.
(Reference: “4.2.5 Liquid sealant”)

If a coating is not applied at some points within the coating range, it could cause leakage of the
lubricant.

If the leaking liquid sealant enters the reduction gear, it could cause deterioration of performance,
such as abnormal noise, vibration, and torque irregularity. Also, if the liquid sealant adheres to the lip
of the oil seal, it could cause leakage of the lubricant.

If it leaks into the shaft mounting bolt section, it could deteriorate the bolt tightening force, and
eventually result in deterioration of the transmission torque.
