When using the Servomotor in an environment where the Servomotor shaft will be exposed to oil,
select a Servomotor with an oil seal.
Precautions
 Keep the oil level below the oil seal.
 The Oil Seal is made of rubber and may burn if it is used in an environment where it is subjected
to no oil at all. Always use the Servomotor in an environment with a suitable amount of oil.
 Install the Servomotor so that oil does not accumulate around the oil seal.
 Other Precautions
 Take measures to protect the shaft from corrosion.
The shafts are coated with anti-corrosion oil when shipped, but anti-corrosion oil should be
removed when connecting the shaft to a load.
