5.2.4 Lubricants
WARNING
Do not mix different types of grease.
Incompatible lubricants may cause bearing damage.
When regreasing, use only special ball bearing grease with the following properties:
– good quality grease with lithium complex soap and with mineral- or PAO-oil
– base oil viscosity 100-160 cST at 40°C
– consistency NLGI grade 1.5 - 3*
– temperature range -30°C - +110°C, continuously.
*) For vertical mounted motors or in hot conditions a stiffer end of scale is recommended.
The above mentioned grease specication is valid if the ambient temperature is above -30°C or below +55°C, and the bearing temperature is below 110°C.
Grease with the correct properties is available from all the major lubricant manufacturers.
Admixtures are recommended, but a written guarantee must be obtained from the lubricant manufacturer, especially concerning EP admixtures, that
admixtures do not damage bearings or the properties of lubricants at the operating temperature range.
WARNING!
Lubricants containing EP admixtures are not recommended in high bearing temperatures in frame sizes 280 to 355.
The following high performance greases can be used:
- Esso Unirex N2 or N3 (lithium complex base)
- Mobil Mobilith SHC 100 (lithium complex base)
- Shell Albida EMS 2 (lithium complex base)
- Klüber Klüberplex BEM 41-132 (special lithium base)
- FAG Arcanol TEMP110 (lithium complex base)
- Lubcon Turmogrease L 802 EP PLUS
- Total Multiplex S 2 A (lithium complex base)
NOTE!
Always use high speed grease for high speed 2-pole machines where the speed factor is higher than 480,000 (calculated as Dm x n where Dm=average bearing
diameter, mm; n=rotational speed, r/min).
The following greases can be used for high speed cast iron motors but not mixed with lithium complex greases:
- Klüber Klüber Quiet BQH 72-102 (polyurea base)
- Lubcon Turmogrease PU703 (polyurea base)
If other lubricants are used:
Check with the manufacturer that the qualities correspond to those of the above mentioned lubricants.
WARNING!
Lubrication intervals listed above, are based on the use of high-performance greases such as those listed above, the use of other thypes of grease can reduce
the lubrication intervals listed
