Regreasing intervals and types of grease for operating roller bearings

The specified grease data applies to the data specified on the rating plate and for high-quality
grease in accordance with the specifications in these operating instructions. Because these
greases exceed significantly the requirements according to DIN 51825 and ISO 6743‑9, they
permit the specified relubrication intervals.
Initial lubrication
The grease specified on the lubricant plate is selected according to the operating conditions
known at the time of ordering and should be used for initial lubrication.
Criteria for selecting rolling bearing greases
High quality ISO‑L‑X BDEA3 lubricating grease according to ISO 6743-9 and K3K‑20
lubricating grease according to DIN 51825 with lithium soap as a thickener and an upper
service temperature of at least +130° C / +266° F are permissible for standard applications
without special requirements.
● The technical data of the rolling bearing grease must be suitable for the application.
● Only use the grease type that is specified on the lubricant plate.
● If the operating conditions differ from those mentioned, other lubricating greases may only
● If lubricating greases other than those named on the lubricant plate are used, it cannot be
● The lubrication properties will be impaired if you mix different lubricating greases. This can
