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
● The lubricating grease must satisfy the criteria listed in the table below and must match the
