Spherical roller bearings often operate in challenging environments with virtually inevitable dirt ingress and bearing grease loss. In fact, independent SKF analysis has shown that 50% of premature bearings failures are caused by poor lubrication or ingress of contaminants.

What’s more, since the assets that rely on bearings for operation are often those crucial to your production processes, any downtime can lead to costly stops in manufacturing.

Vibrating Screening

 

A full range of reliability

In most industrial environments, every minute of downtime is critical. Contaminated environments, heavy radial and axial loads, misalignment, problems with leaking grease all add to the growing costs, and not to mention the potential risks to workplace and worker safety.

But with sealed SKF Explorer spherical roller bearings, you are fully equipped to meet these challenges head on.

Pre-lubricated with a specially formulated grease and sealed with high-performance contact seals, they can protect the bearing and lubrication from contaminants that might otherwise cause premature bearing failure.

 

Their high load capacity and ability to accommodate misalignment further helps to reduce maintenance costs and prolong bearing service life. By keeping contaminants at bay and lubrication in, SKF Explorer spherical roller bearings simply provide longer meantime between failure, reduce overall costs, improve worker safety, and reduce your environmental footprint.

Did you know, by switching from an open to a sealed design makes it possible to increase bearing rating life by up to four times in the contaminated environments typical of heavy industrial applications? A real long-term investment for increased machine availability and reliability, you might say ‘they are the future of reliable operations.

Improving H&S

Recent HSE analysis has indicated that 25-30% of manufacturing industry fatalities in Britain were related to maintenance activity and slips, trips and falls account for 29% of non-fatal UK workplace injuries – very harrowing and damning statistics.

One of the common maintenance practices for open bearings is to purge the bearings with grease – increasing costs, as well as increasing health and safety risks for maintenance personnel, as bearings are often located in inaccessible and hard to reach areas of industrial plants and associated machinery.

So, by introducing sealed SKF Explorer spherical roller bearings to your assemblies, grease leakage and spillage are reduced through the removal of purge processes.

The combination of increased MTBF and reduced lubrication activity means fewer maintenance interventions, helping to reduce the risk of injury to your employees.

Sealed for Success

Benefits of using SKF Explorer bearings include:

  • Significantly extended service life
  • Increased uptime and productivity
  • Extended lubricant life
  • Reduced sensitivity to misalignment
  • Reduced noise and vibration
  • The prospect of downsizing applications

Helping the environment

In many typical applications, sealed SKF Explorer spherical roller bearings can be considered lubricated for the full life of the bearing; in other large size applications, these bearings have been proven to reduce grease consumption by up to 95% leading to lower environmental impact and costs.

Additionally, by protecting the bearing in operation, the possibility of remanufacturing large sized sealed spherical roller bearings, not just once, but twice, is increased. Depending on the amount of remanufacturing required, up to 90% less energy is needed to remanufacture a bearing instead of manufacturing a new one from scratch.

Think of it this way… with potentially 95% less grease consumption, and 90% less energy for manufacturing, it’s hard to say that sealed SKF Explorer spherical roller bearings aren’t the most environmentally conscious option.

Not short on options

SKF offers the industry’s widest range of sealed spherical roller bearings, with bore diameters ranging from 25mm to 1250mm. In fact, SKF are the only manufacturer whose full standard range of spherical roller bearings up to an outer diameter of 420mm are all available sealed, off-the-shelf.

Additionally, certain bearings in the 222- and 223-series are designed slightly wider to accommodate the seals; but over 100mm bore, most of the series are dimensionally interchangeable with their open cousins.

With a new design that results in up to 50% less seal friction, SKF’s small sealed spherical roller bearings also reduce operating temperatures by as much as 20°C, enabling SKF to double the limiting speed rating. As a result, more applications can benefit from the superior contamination protection of sealed SKF spherical roller bearings.

Add real value

Extending maintenance intervals, improving productivity, and reducing grease consumption, application, and disposal clearly offers tangible reductions in your Total Cost of Ownership (TCO). So, when combining with lower risk to employees and less environmental impact, why wouldn’t you consider switching to sealed SKF spherical roller bearings if you’re looking to add real value to your business.

Unlike some other costly, complicated solutions, SKF sealed Explorer spherical rolling bearings offer a quick and simple solution, with minimal capital cost outlay and very short return on investment.

Taking into consideration all of the advantages over open bearing assemblies and other bearings on the market, SKF sealed Explorer spherical roller bearings are ‘a real, simple win, win, win, win solution.
