4.5 Lubrication

Ratings and Lubricants
Harmonic Drive® products achieve the specified ratings and characteristics in the standard ambient temperature range
(0° C to 40° C) when they are used with the lubricants named in the catalogue. Harmonic Drive AG can guarantee for the data
specified in the catalogue only if a Harmonic Drive® grease or a mineral oil named in the specific product chapter is used. Others
than the lubricants and lubricant quantities recommended from Harmonic Drive AG should be qualified by means of prototype
tests, if necessary.
The warranty becomes void when lubricants that have not been recommended in the Harmonic Drive® catalogue or that have
not been approved in writing for the specific application are used.

4.5.1 Grease Lubrication

Application of Harmonic Drive® Lubricating Grease
Depending on product, size and if necessary ratio, the matching Harmonic Drive® grease should be selected. We recommend
the application of the Harmonic Drive® lubricating grease Flexolub®-A1 for all Units of the CP series.
Caution!
The Harmonic Drive® high performance 4BNo.2 grease becomes relatively thin fluid during operation. Therefore the design
must be oil-tight. Because of the special characteristics of this grease a small base oil leakage at the oil seals can not
completely be excluded. We recommend to use FPM (Viton®) oil seals.
