Installing the gear unit
Mechanical Installation
Secure gearmotors using quality 8.8 screws.
Secure the following gearmotors using quality 10.9 screws:
• RF37, R37F with flange Ø = 120 mm
• RF37, RF47, R47F with flange Ø = 140 mm
• RF57, R57F with flange Ø = 160 mm
• FF, FAF, KF, KAF with flange Ø 250 mm
• and RZ37, RZ47, RZ57, RZ67, RZ77, RZ87
At the same time, also check that the oil fill corresponds to the specifications for the in-
tended mounting position (see chapter "Lubricant fill quantities (page 139)" or refer to
the information on the nameplate). The gear units are filled with the required oil volume
at the factory. There may be slight deviations at the oil level plug as a result of the mount-
ing position, which are permitted within the manufacturing tolerances.
Adjust the lubricant fill volumes and the position of the breather valve accordingly
in the event of a change of mounting position.
Observe chapter "Lubricant fill quan-
tities" and chapter "Mounting Positions".
Consult the SEW customer service if you intend to change the mounting position of K
gear to M5 or M6 or between M5 and M6.
Please contact our SEW customer service if you want to change the mounting position
of size S47 – S97 helical-worm gear units to mounting position M2 or M3.
Use plastic inserts (2 – 3 mm thick) if there is a risk of electrochemical corrosion between
the gear unit and the driven machine. The material used must have an electrical leakage
resistance < 10

Ω
. Electrochemical corrosion can occur between various metals, for ex-
ample, cast iron and high-grade steel. Also fit the bolts with plastic washers. Ground the
housing additionally – use the grounding bolts on the motor.
INFORMATION
When installing the gear unit, make sure that the oil level and drain plugs as well as
the breather plugs are easily accessible!
