Applications

IT TAKES MUSCLE TO HANDLE MUSSELS

FOR EXTREMELY HARSH CONDITIONS SUCH AS IN 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 what is 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 of Yerseke where mussels are a big industry, experience shows that a normal bearing lasts three months whereas the Extreme Bearing lasts three years or more on average 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 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.

NO DOWNTIME DESPITE CRACKED SHELLS AND SEAWATER

THE BEARING IS HEAVILY LOADED AND CONTINUOUSLY SPRAYED WITH SEAWATER.

The seats are machined to a tolerance to provide a loose fit.

The photo shows the start of a conveyor belt carrying mussels at the Prins & Dingemanse factory in Yerseke, the Netherlands. An Extreme Bearing has been fitted on the belt and is clearly visible with its blue end cap. As can be seen, the Extreme Bearing is surrounded by fragments of broken shells while salt water is running down from the conveyor.
Despite these tough conditions, when the end cap was removed after one year of operation and the bearing was inspected, there were no signs of contamination or wear.
The end cap was put back on and the mussel line could continue working without interruption.

EXTREME BEARING USED ON SHRIMP PEELING MACHINE

HIGH SPEEDS AND LONG THIN DRUMS BUT EXTREME BEARINGS TAKE THE STRAIN

In a shrimp peeling machine used at a factory run by International Shellfish in the Dutch town of Yerseke, the drums are only 1 inch in diameter. The length of the drums is 3 metres and the drums are rolling extremely fast. This means the drums have a tendency to bend and normal bearings cannot cope well with the high speeds and extreme axial displacement. In addition, the conditions are corrosive with the presence of salt water and the use of caustic chemicals for cleaning. Only one bearing was considered good enough for this application: the Extreme Bearing.

BEARINGS USED IN THE VEGETABLE INDUSTRY

PEAT AND ROOTS DON’T STOP AN EXTREME BEARING

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.

AN ACID-PROOF BEARING – THE PROOF FROM A PICKLING PLANT

BEARING PILLOW BLOCKS PLACED ABOVE BATH CONTAINING FORMIC ACID.

Extreme bearings have been installed in the machinery used for pickling mussels at the Prins & Dingemanse factory in Yerseke, the Netherlands. As shown here, the bearings are placed right above a bath of concentrated acid. The fumes are extremely strong and are enough to corrode a normal bearing. However, the Extreme Bearing has an excellent seal that keeps out the acidic vapours and protects the bearing from corrosion. The bearing has been in operation so far for 24 months at this factory without any problems.
