Grease lubrication (Gear motors, hypoid motors, mini series )

1. Grease lubrication

Grease lubrication system is used for lubrication.

2. Grease filled

A specified amount of lead-free grease is already injected prior to delivery. Use the motor as is.

3. Grease replacement

Grease does not need to be replaced or replenished in most cases, but it will last longer if it is replaced around 20,000 hours. Grease replacement is available at our repair shop for a fee.

Oil lubrication (Croise Motor )

1. Oil lubrication

Oil is used for lubrication.

2. Oil injected

A specified amount of oil (Daphne Alpha Oil TE260) is filled at the time of delivery. Use the motor as is.

3. Oil change

  • ・Reducer frame numbers 13 to 28 have a sealed structure. Consequently, replacing or refilling lubricating oil will not be necessary in most cases. However, if operating conditions cause severe deterioration in the lubricating oil, change the oil after 2500 hours of operation. Doing so will extend the service life of the unit.
  • ・For frame numbers 32 to 50, maintenance is as follows:
  • (1)For the first time after initial start of operation, change the oil shortly after 1,000 hours of operation or after a period of three months.
  • (2)Subsequent changes: Depending on operating conditions, 5000 hours or one year, whichever comes first.

4. Pressure vent

  • ・Reducer frame numbers 13 to 28 have a sealed structure.
  • ・For frame numbers 32 to 50, be sure to check that the reducer is mounted in the standard installation direction and then install the supplied pressure vent. After installation is complete, check the oil level using the oil gauge.
    For other than the standard installations, please specify at the time the order is placed.

5. Recommended lubricating oils

Manufacturer Recommended lubricating oil
Industrial gear oil Class 2 (Worm gear ) ISO VG320
EMG Lubricants Mobile 600 W cylinder oil (ISO VG380)
Spartan EP320
Showa Shell Sekiyu Shell Omala S2 G 320
Idemitsu Oil Daphne CE compound 320S

Maintenance when using the recommended lubricating oils in the table above is as follows:① For the first time after initial start of operation, change the oil after 500 hours of operation.② For the second time onwards, change the oil after every 2,500 hours of operation, depending on operating conditions.

  • Note 1)The oil amounts above are for standard mounting directions (mounting No. 0 or No. 1).
    Regardless of the motor kW and reduction ratio, the same amount of oil is used for reducers with the same frame numbers in the same series.
  • Note 2)For mounting No. 5 of the HCMA/HCMR series, increase the oil amount by 60% (approximate oil amount).
