Typical Applications 

It takes muscles to handle mussels !

For extremely harsh conditions such as the shellfish industry

Declumping is the mechanical process of separating mussels by tearing apart the mussel clumps.

In an application like this, the extremely high specifications of the Extreme Bearing are required: durable bearing housing, rust resistant, water resistant, capacity to withstand heavy forces and axial force.

This is the industry for which the original Extreme Bearing was developed, simply because ordinary bearings were wearing out too fast. In the Dutch seaside town Yerseke, where mussels are a big industry. Experience has shown that a normal bearing lasts three months, while the Extreme Bearing lasts three years or more before it needs replacement.

Food on the move

Perfect for fresh fruit and vegetable conveyor belts

Extreme Bearings are, as the name implies, designed for use in harsh environments where relatively cheaper alternatives soon fail.These kinds of environments can be found in the food industry.

Typical conditions:

  • Cleaning with a high pressure jet and aggressive chemicals
  • Heavy conveyor belts for fruit and vegetables.
  • Places where the metal is attacked by fruit juices.
  • Fruit and vegetables are washed and sorted with the aid of water

Common problems such as damaged or cracked inner rings and dysfunction of the bearing housing are prevented by Extreme Bearings.

The AISI 316 stainless steel enclosures provide resistance to corrosion in many industries.

The application of special seals and a grease filling into the housing contributes to a perfectly sealed housing.

Heavy loads

For bearings on places which are difficult to maintain

 Extreme Bearings provide a long working lifetime for applications in hard-to-reach places where maintenance needs to be reduced to a minimum.
  • Can carry 5 times more load than conventional bearings.
  • Triple sealing: both on the outside and the inside: 1, the oil seal; 2, grease packing and 3, the 2-rse bearing seal (Note that number 3 is only included with the ball bearing insert)
  • Housing made of highest grade stainless steel: 316.
  • The cover is bolted onto the housing so these cannot be lost.

Extreme bearings cope with conditions in mussel processing

The bearing is heavily loaded and continuously sprayed with seawater.

Grit, sand and shells gather between the conveyor frame and the pillow block of the bearing. And there is also the constant presence of salt water around the bearing.

Thanks to the 316 stainless steel bearing and centrifugal seals, the Extreme Bearing has been running in this exposed position for many years without maintenance.

Extreme Bearing used on shrimo peeling machine

Long bending axes, axial force and high speed

When conveyor belts are tensioned over rollers with long, thin axes as in a shrimp peeling machine. The roll will bend and this will ruin the shaft. Extreme Bearing will absorb misalignment without generating force in the bearing. This ensures a long bearing working life.

Peat and roots don’t stop an Extreme Bearing

The bearings have to withstand soil, roots and water

An engineering company in Mechelen in Belgium was designing equipment for the automatic handling of vegetables such as lettuces in greenhouses. The company wanted bearings that were out of the ordinary due to the difficult dirty conditions on the conveyor belt with wet peat and roots. Normal bearings would soon become clogged up and inoperative. It took two years of thorough testing before the company decided on the best bearing for this application: finally in January 2016, they chose the 1-inch diameter Extreme Bearing for their new equipment.

Bearing pilloe blocks used in pickle industry 

Bearing pillow blocks placed above bath containing formic acid.

Because there is a very aggressive vapour over the bath containing formic acid, the choice of bearing was easy: an Extreme Bearing with a housing made of 316 grade stainless steel.

Extreme Bearings on sea

Seaweed harvester

The seaweed grows in belts between the boundaries of the lowest tides and the half tides.  It is harvested while floating when the tides are not too high. The Seaweed Factory owns a few rafts made of steel floats, equipped with spade wheels, adjustable cutters in front and conveyor belts this is where the water resistant SS 316 Extreme Bearing been used.
Seaweed is a commercially important food, especially in Japan, where it is called nori and is harvested mainly from red algae, extensively cultivated on bamboo screens submerged in estuaries. Agar, also derived from red algae, is consumed as a delicacy in Asia and is used as a laboratory medium for culturing micro-organisms. Red algae are probably of little nutritive value to human beings, however, other than for their limited protein, vitamin, and mineral (especially iodine) content. Brown algae are used as fertilizer and as an ingredient for livestock meal. Alginic acid, found in kelp, has wide industrial uses. It can be made into a silk-like thread or a plastic material, insoluble in water, used to make films, gels, rubber, and linoleum, and as a colloid in cosmetics, car polishes, and paints. Organic derivatives of alginates are used as food gums in making ice cream, puddings, and processed cheeses.

Underwater solution 

Waste burning facility

Underwater solution for a waste burning facility. Hot ash is falling into the water to ensure that it is not burning anymore. The conveyor belt has to carry the ash out of the water tank and transport it into a container. The water in this case can

reach boiling temperature. Extreme Bearing: drown them, boil them – rely on them!

Extreme Bearing

Going wild with salmon!

EXTREME BEARING are highly resistant against acid and alkaline industrial agents which are used for cleaning operations in the fishing processing industry, saltwater operations and outside pressure resistance up to 30 bar. With EXTREME BEARING bearing housing units Norlaks got the opportunity to enlarge significant the lifetime of bearings which are used within there processing lines  and reducing significant breakdowns because of insufficient bearing performance!
