Ceramic Bushing Lubrication

In applications lubricated by water or process fluid bearing materials need to be both chemically resistant to the fluid and able to operate with thin films.

Ceramic bushing lubrication.

Given the lower speed and load the bearings will be subject to in a mount you should be fine running them dry. There are ptfe grease formulations for full ceramic bearings but they are used more in higher speed applications such as cycling. Prevent electrical arcing when electrical current passes across bearings a washboard pattern appears on the raceways along with a darkened grey appearance. Grease and oil are common lubricants for hybrid bearings but ceramic bearings are less sensitive to fluctuations in lubrication conditions.

Grease specifications are subject to application in order to decide which grease type is most applicable to your application contact unasis sales team. Grease and oil lubricants can also be added to full ceramic bearings as well as hybrids in order to change performance characteristics such as increase speed reduce ball skidding or reduce noise. Typical results include bearing surface damage premature aging of the lubricant. For example compared to steel bearings ceramic balls can operate under the same lubrication conditions at speeds up to 20 higher.
