Grease Lubricated Models
Those models listed in Tables A-3 - A-6 as grease
lubricated are filled with grease before shipment to the
customer and are ready for use.

Table A-8. Grease Replenishment and Change Interval
Replenishment and Change Guidelines
Rep!enish grease to the reduction mechanism 113 to 112 of
the quantity listed in Table A-9 or
A-1 0 for the first reduction
stage at the interval recommended in Table A-8.
When the unit is disassembled for overhauling, refill with
the grease quantities indicated in Table A-9 or A-10. Or
alternatively, 80% of the space around the reduction
mechanism and slow speed shaft bearings of single
reduction units, and
50O/0 around the reduction mechanism
of both the first and second stage of double reduction units.
Sligh.tly larger quantities may be supplied to lower reduction
ratio units, and somewhat smaller quantities for high
reduction ratio units.

Single and Double Reduction
Maintenance Free Type
Double Reduction
Apply grease liberally to the central part (i.e., around the
eccentric bearings) of the mechanism. Apply grease to both
the slow speed and high speed shaft bearings as you would
to ordinary bearings at the time of re-assembly.
If excessive grease is added, agitation heating of the grease
will raise the operating temperature of the unit. Avoid
excessive greasing, but do not supply an insufficient amount
of grease. When the grease is insufficient, it will raise the
unit's operating temperature due to breakdown of the
lubrication films on the eccentric bearing. In this case, if the
operal:ing temperature rises, supply grease immediately.

Notes:
[I] Avoid the use of grease other than shown in Table A-7.
[2]Consult the factory when the drives are used under widely fluctuating temperatures, ambient temperatures other than those listed in
Table A-7, or any other special conditions.
[3]Single reduction frame sizes 6060 - 612H and double reduction frame sizes 6060DA - 6125DB are maintenance free units. Grease
replenishment is not necessary. Where longer life of the drive is expected or if re-lubricating is preferred before the recommended
interval, refer to Tables A-7, A-8, A-9 and A-10.
[4] Overhauling consists of disassembling the unit, replacing the seals and gaskets, cleaning the internal parts and then repacking the
unit
with designated grease.
