The following lubricant quantities are required:
• For fast-running bearings (motor and drive end of gearbox): fill approx. one-third
of the hollow space between rolling bodies with grease.
• For slow-running bearings (in gearbox and driven side of gearbox): fill approx.

8.2.3 Table of lubricants
 Note!
Please note that the recommendation of a lubricant/grease or its listing
in a Lenze lubricant table does not mean that Lenze is liable for these
lubricants or damages resulting from incompatibilities of materials used.
For Lenze drives, the lubricants listed in the lubricant table on the following page are
permitted. Special lubricants must be used, for instance for longtime storage or
special operating conditions. These corresponding lubricants are available at a
surcharge.
For the lubricant selection observe the following legend relating to the lubricant
table!
CLP  Mineral oil
CLP PG  Polyglycol oil
CLP PAO  Synthetic hydrocarbons or poly-alpha-olefin oil
CLP E  Diester oil (water pollution class 1)
1)  Currently no test results are provided yet for the efficiency of the specified
lubricants for worm gearbox lubrication. Iftheseoilsareused,thepermissible
torque must be reduced to 80% of the catalogue values.
2)  Polyglycol oils cannot be mixed with other types of oil
3)  For ambient temperatures above 40°C please consult us and specify the exact
operating conditions!
4)  Observe critical starting performance at low temperatures! Temperatures below
-25°C require special measures for the motor bearing and NBR shaft sealing
rings!
5)  Ambient temperature range
