 Oil Seal
The Servomotor oil seal dimensions are given below. The expected service life of an oil seal is
approximately 5,000 hours. The actual life depends on the application conditions and environment.
Oil seal installation and replacement are treated as repair work. For inquiries, consult your OMRON
representative.
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.
 If there is no oil at all on the oil seal, the oil seal, which is made of rubber, will be glazed. 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.
