Extreme Bearing seals
An important advantage of Extreme Bearing block housings is that they can be fitted with different types of seals. Standard Extreme Bearing seals include radial seals, labyrinth seals, centrifugal seals. An we also provide PTFE seals and heavy-duty ceramic seals with a radial labyrinth.
The Extreme Bearing units, as a standard, are assembled with type AS radial seals. All seals are easy to install and can be supplied separately. The standard seals are shown in table 1, with an overview of the seal type. And you can also see its design features and suitability for various operating conditions susch as bearing seals for wahsdown and submerg aplications. Detailed information about standard and special seals can be found in the table.
SA Radial oil bearing shaft seals are the standard Extreme Bearing seals.
Excellent chemical resistance
A good option for difficult and extreme conditions.
Duo seal. The DS seal combines the advantages of two seals in a single seal set.
The WS seal is a wrapping seal, because it is wound around the shaft against the direction of rotation.
VK seals blue NBR rubber caps designed to closed the bearing unit when the shaft is ending in the bearing.
A bearing is only as good as the seal
We realise that a seal to resist a corrosive chemical should be different. To one that will be used in a powder handling plant. Or in the mining industry to keep out dirt and dust. Temperature variations and the speed of the shaft will also affect the choice of seal. That’s why we offer a range of seals. And we have also developed our own designs. For example, many Extreme Bearing units feature our own centrifugal seals (CS). Especially developed to repel dirt and contaminants. Using centrifugal force generated by the shaft.
We also offer some seals that are completely maintenance-free. So the bearing unit is sealed for life. This is especially useful if the bearing is in an inaccessible place. Or if maintenance service is infrequent. In some cases, we will develop a one-off sealing solution. Specifically for one customer.
Maintenance-free
Many sealing options are possible. Because within the Extreme Bearing housing blocks, several different seals can be assembled. We offer flexibility. And would be pleased to advise you on the best choice of seal. For your particular application. Nothing is standard for us!
The Type E bearing seals are designed to provide an extra barrier to prevent contamination from entering the bearing
