Grease systems have been popular in lubricating bearings located in the spray chamber of a caster.  However, the harsh and steamy environment leads to an influx of water into the bearing between grease lube cycles and eventual destroys it.

 Air-oil not only lubricates, but also pressurizes the bearing cavity preventing water and dirt ingress from happening.

Installation of air-oil systems at several U.S. steel mills have resulted in a substantial increase in bearing life.  All mills have reported an improvement in their number of slab heats. One steel mill in particular has experienced an increase from 1,200 heats with grease to over 9,000 using air-oil over the past 8 plus years
