2. Assembling the bearing 【Bearing assembly】
①
Put the bearing case and bearing case
cover A together.
②
Insert bearings A, B, and C each into the shaft
with a pressure of about 10 MPa. When
inserting a bearing, apply force on the inner
race of the bearing. Do not strain the bearing.
※ When using a hammer to insert a bearing,

be careful not to directly hit the shaft or bearing.
③
Assemble bearing case cover B.
④
Attach the key to the shaft.
⑤
After finishing assembling all the parts, turn the shaft by hand
to check whether the shaft moves stiffly or jerkily. Gently shake
the shaft tip right, left, up, and down to check the shaft for
looseness.
3、Assembling the rotating parts 【rotating parts】
①
Insert the deflector into the shaft and attach the seal case to the bearing assembly. At this moment,
apply liquid gasket to the contact surface between bearing assembly and seal case.
②
Insert the seal washer and sleeve (attach the O ring to its inside) into the shaft in this order.
※ Before inserting the sleeve, properly remove dust and dirt from the shaft and sleeve.
③
Attach the mechanical seal in the order
shown in the figure on the right.
※ Prevent dust and dirt from adhering
to the sliding surface of the
mechanical seal.
※ Be careful with the sliding surface
of the mechanical seal; it is very fragile.
