1.4 Maintenance Method

• Washing of Miniature Stroke Bearing

(1) Wash the MSB shaft and the outer cylinder

with kerosene in the supersonic cleaner for

approx. 5 to 10 minutes.

(a) Do not wash the cam follower

section of the MSB shaft.

Be sure to use a cleaning jig to

prevent any cleaning solvent from

touching the cam follower section.

(b) Alcohol can also be used in place

of kerosene.

In this case, wipe the surfaces of

the MSB shaft and the outer cylin-

der quickly after washing and

grease them up.

(2) Apply the pressure of air blowing to the MSB

shaft and the outer cylinder to blow off the

internal dirt and kerosene.
