Lubricant compatibility with oil seal
Approval
Explanation
SEW07004_ _13: A lubricant especially recommended with regard to compatibility
with the approved oil seals. The lubricant exceeds the state-of-
the-art requirements regarding elastomer compatibility.
Approved application temperature range of the oil seals
In the low temperature range, oil seals can withstand shaft deflections (e. g. through
overhung load) only to a limited extent. Especially avoid or limit pulsating or changing
radial displacements of the shaft. Contact SEW‑EURODRIVE, if required.
