Step 5
Attach the O-ring to the shaft mounting surface
of the reduction gear.
• If the model does not have an O-ring groove or
an O-ring cannot be used due to its structure,
seal the section by using a liquid sealant, etc.
When sealing with an O-ring
• For models RV-160N, 380N, 500N, and 700N of the
catalog products described in “2.2 Parts codes of
catalog products”, an O-ring groove is provided on the
shaft mounting surface.
• When sealing the section with an O-ring, fit the O-ring
into the groove at the shaft edge.
(Reference: “4.2.5 O-rings”)
An O-ring (II) groove may also be provided on some products not included in the catalog. In such a
case, attach the O-rings indicated in the separately provided “External dimensions” drawings and
specification sheet.
When sealing with a liquid sealant
• When sealing the section with a liquid sealant, coat the
liquid sealant onto the section at the shaft edge.
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 detailed coating procedure, follow the
instructions given by the manufacturer of the sealant to
be used.
