To be replaced if any
abnormality is found.
In case of replacing the main/side bearings of No.27 and No.28, it is not necessary to prepare the
O-rings of No.432 and No.433 because the main/side bearings have the O-rings.
The sizes of O-ring No.432-2 and No.432-2 have been changed to G130 from G135 in October 2012
as a design modification.
● The part code of the O-ring is the one assigned to NBR which is standard material.
When the material of the O-ring is other than NBR, a different part code is used for
each material.
If you are using O-rings made from other than the standard material, please contact
us when placing an order.
