Sealing solutions eliminate contamination to boost MTBF

摘要

More than half of all bearing failures are caused by contamination of the bearing oil due to inefficient sealing. With the availability of cost-efficient sealing solutions which can eliminate contamination and increase MTBFs from months to years, bearings failure should be the exception, not the norm, says Chris Carmody of AESSEAL. Bearings failure accounts for roughly 40% of all failures in pumps and other rotating equipment, leading to costly downtime and equipment repair and replacement. Almost 50% of those bearings failures are caused by contamination of the lubrication oil, most commonly by water, process fluid or particles of dust and dirt. The ingress of moisture or particles into the bearings chamber might be minute, but the impact on efficient operations can be anything but.
