5x Higher Load Capacity


Extreme Bearing housings are made of stainless steel 316 

with a double row of rollers and a special seal.

They are a better choice for applications on food processing conveyors

 where traditional bearings quickly become worn down by heavy load, rust, 

soiling, dust, chemicals and the penetration of water.

what is aN extreme bearing?

Extreme Bearing housings are made of stainless steel 316 with a double row of rollers and a special seal.

They are a better choice for applications where traditional bearings quickly become worn down by heavy load, rust, soiling, dust, chemicals and the penetration of water.

Extreme Bearings are designed for tough and wet corrosive environments involving heavy loads such as on conveyors, wash drums and graders in potato and seafood processing factories. Thanks to the excellent seals, Extreme Bearings are also very suitable in dry places where there is a lot of dust in combination with heavy bearing loads such as in mining and the extraction of sand on sorting equipment, conveyors and crushers.

                   Technical features:

  • The housing is made of stainless steel 316.
  • The bearing unit is interchangeable with most known brands of housing and can therefore be used in existing operating machinery.
  • Self-aligningdouble row ball bearings to handle high radial and thrust loads.
  •  Particularly suitable in harsh conditions and where agressive media is used.
  •  SS 316 has a very high resistance to chemicals and sea water.
  •  Standard bearing insert, so a replacement bearing insert can be found anywhere in the world.
  •  IP66: water projected in powerful jets against the enclosure from any direction shall have no harmful effects.
  •  The bearings are very easy to clean. Rounded corners and smooth surfaces both at the front and reverse side do not encourage the build-up of dirt or the growth of microorganisms.
  •  Extreme Bearing housings are available in shaft diameters from 25 to 100 mm.


Extreme Bearing has been developed TO ELIMINATE the need for the FREQUENT REPLACEMENT of Bearings

A chain is only as strong as its weakest link. So even if the bearing insert itself is made of chrome steel or strong stainless steel, in many industrial applications the housing is frequently made of plastic or lower grade stainless steel (304).

These combinations are then usually sealed with plastic caps, with or without seals, in order to keep out contaminants. In practice, it has often been found that these systems are not adequate.

External factors, such as moisture and alignment errors, impact negatively on the bearing system requiring the premature replacement of parts.

All traditional bearing units contain ball-bearing inserts, fitted with a spherical outer ring. The idea is that the bearing is self-aligning. However, this is not always the case.

What usually happens is that the force on the shaft holds the outer ring firmly in the bearing housing, making it impossible to move and adjust itself. The forces generated cause damage to the balls, inner ring and ball race. Ultimately the bearing unit has to be replaced.

We developed the Extreme Bearing system on the basis of knowledge and experience gained in everyday practical situations.
