43.4 Factors influencing lubrication intervals
The indicated relubrication intervals must be halved for vertically mounted motors. The indicated lubrica-
tion intervals are based on a bearing operating temperature of 80°C (ambient temperature approx. +25°C).
The bearing temperature will rise in accordance with the ambient temperature. If the bearing temperature
increases by 15°C, these values must be halved; if the bearing temperature decreases by 15°C, these val-
ues can be doubled.
CAUTION!
The max. permitted temperatures for lubrication grease and bearing must not be surpassed!
43.5 Lubricants
CAUTION!
Incompatible lubricants can lead to damage to the bearing.
Always use the same lubricant for one motor.
For relubrication always use grease specifically designed for the lubrication of ball bearings with the follow-
ing characteristics:
•
High-quality grease with lithium complex soap and mineral or PAO oil
•
Base oil viscosity of 100-160 cST at 40°C
•
Consistency NLGI grade 1.5 to grade 3. (A stiffer NLGI grade is recommended for vertically mounted
motors or hot ambient conditions).
•
Temperature at continuous operation -30°C to +120°C
Compatible greases with the required characteristics are available from any larger lubricant manufacturer.
The following high-performance greases can be used:
•
Esso Unirex N3
•
ESSO / Mobilux EP3
•
ARAL / Aralub 4340
•
Fuchs / Renolit FWA 220
•
SHELL / Alvania RL3 (old G3)
•
SHELL / Alvania R 3
•
WINTERSHALL / Wiolub LFK 3
•
DEA / Glissando 30
CAUTION!
Avoid using lubricants with EP additives at high bearing temperatures in axle heights 280-450.
Additives can be favourable, a written guarantee for EP additives in particular, however, regarding their
harmlessness in terms of bearing damage or temperature resistance of the lubricant, can only be pro-
vided by the lubricant manufacturer.
