Weg Motor Greasing Guidelines
Lubrication Procedure
Machines without Grease Nipples
Motors up to frame size 215T are normally fitted without grease fittings. In these cases the
regreasing shall be done during preventive maintenance service paying attention to the
following aspects:
1. Take motor apart carefully.
2.
Take all the grease out.
3. Wash the bearing with kerosene or diesel.
4.
Dry the bearings
5. Regrease the bearing immediately.
Motors Fitted with Grease Fitting
It is strongly recommended to grease the machine while running. This allows the grease
renewal in the bearing housing. When this is not possible due to rotating parts by the
grease device (pulleys, bushing, etc.) that offer some risk to physical integrity of the operator,
proceed as follows:
1.
Clean the area near the grease nipple.
2. Put approximately half of the total grease and run the motor for 1 minute at full speed.
3.
Then turn off the motor and pump in the rest of the grease.
Note: The injection of all the grease with the motor in standstill can make the grease penetrate into the motor,
through the bearing housing inner seal.
Approved Grease
• Mobile Polyrex EM Grease
Special Note
The table below is specifically intended for relubrication with MOBIL Polyrex EM grease and
bearing absolute operating temperature of:
• 70°C (158°F) for 254/6T to 324/6T frame size motors
• 85°C (185°F) for 364/5T to 586/7T frame size motors
• For every 15°C (59°F) above these limits, relubrication intervals must be reduced by half.
• Shielded bearing (ZZ) are lubricated for bearing life as long are they operate under
conditions and temperature of 70°C (158°F).
***When motors are used on the vertical position, their relubrication interval is reduced
by half if compared to horizontal position motors.***
On applications with high or low temperatures, speed variation etc., the type of grease and
relubrication intervals is given on an additional nameplate attached to the motor.
