Re-greasing with the right lubricant for better performance ExxonMobil is reinventing ways to enhance the durability and performance of rolling element bearings

olling element bearings, often called bearings, are one of the most common components found in modern day machines. It finds its application in a variety of equipment ranging from electric motors to gearboxes as well as conveyor systems. These bearings undergo a regimented lubrication program which involves timely relubrication to replace grease that has deteriorated, leaked away, or become contaminated. It takes on the spot know-how backed by expertise to determine the relubrication intervals in rolling element bearings, owing to the varying conditions these components operate under. The question that now arises is - how often should one relubricaterolling element bearings?
There isn’t a specific answer to this question, since there are numerous factors that influence relubrication frequency. Generally, the smaller the bearing and faster the speed, the less frequent is the interval for relubrication. For instance, ball bearings have a base interval for relubrication, whereas, for a cylindrical roller, the relubrication frequency is almost five times more relatively. Having factored in the causes that determine relubrication intervals and accelerate the process, the immediate requirement to be addressed is the way in which we can mitigate relubrication challenges. ExxonMobilTM offers premium greases for rolling element bearings that can ensure effective relubrication such as:
