Customers are always looking for ways to make bearings last longer, it could be through re-working existing bearings, selecting the correct grease and grease quantity or more importantly the correct seal for the application.
In most split bearing applications the selection of seal is overlooked, and a generic felt seal is used. Whilst felt is a robust material, it is not always adequate enough for the job - the result - the bearings tend to last the warranty period, then the fun begins.
Increase Bearing Life
The correct seal will have a two-fold purpose; to prevent ingress of particulate or media and to prevent lubrication loss. It’s therefore important to consider the environment where the bearing is working and what is the main catalyst for seal failure. If you’re already taking advantage of a split bearing offering 100% continuous concentric sealing if mis-alignment occurs, then it seems only natural you would want the correct seal profile and material for the application.
Whether the split bearing is mounted on conveyor equipment in a quarry or fully submerged in a wastewater treatment plant, the seal you select will determine and affect the life cycle calculation of the bearing in your application. If you consider 14% of premature bearing failures are as a result of contamination, it makes sense to step back and look at what the process is doing and what you’re asking of the bearing and seals.
Bearing operating temperature, contamination levels, speed of rotation, shaft orientation, load are some of the key factors that will determine what seal profile, material and arrangement can be used.
A generic comment I hear from industry is “I didn’t realise there was more than one seal available for split bearings”. Within the suite of seals available from Revolvo there are 8 standard seal arrangements ranging from ideal world to fine dust ingress and full submersion. By using combinations of the standard seals available there are further permissible permutations of sealing arrangements provided.
As a manufacturer of Split Roller Bearings, Revolvo can tailor a sealing solution to be application specific and extend the life of the bearing, so its always best to ask the question.
