• Measure the belt tension at 45 intervals of the shafts. Turn the shafts and
take measurements with a belt tension meter at each point.
Servomotors with Oil Seals
If the Servomotor is used where the shaft opening is subject to oil mist, use a
Servomotor with an Oil Seal. If the Servomotor is used where the shaft opening
is not subject to oil mist, use a standard Servomotor.
The operating conditions for a Servomotor with an Oil Seal are given below.
Note: The oil seal is a single-lip, spring-loaded oil seal made of nitrile rubber
(NBR).
Check the type of oil to be used with the oil seal and make sure that it is
suitable.
• Use the oil seal in a lubricated condition with only splashing of oil.
• Do not use the Servomotor where the oil seal would be below the oil surface.
Oil will enter the Servomotor, which may damage the Servomotor.
