We supply bearings for extreme conditions

Why Extreme Bearings?

All businesses using bearings know the cost of replacing bearing units and the loss of production time during service. The Extreme Bearing has been developed to eliminate the need for the frequent replacement of bearings. And most importantly: to save your company time and money!

Extreme applications

See where Extreme Bearings have been a success and the kind of
applications where these bearings make a significant difference.

Choosing a bearing

Extreme Bearings are customised to your needs. Our experts will help you choose the right Extreme Bearing for your application. You can find all the product specifications of the housings including STP files via the link below. A link to ordering information is also given.

The story of the Extreme Bearing

The life of the bearing increased from months to years

Few industries are tougher on bearings than the mussel industry. Quite simply, the breaking of mussels often wrecks normal bearings. The seawater is corrosive and contains sand. When the mussel shell is broken, pieces of shell can get inside the bearing. The average lifetime of an ordinary bearing on a conveyor belt in a mussel factory is about three months.

How an Extreme Bearing saves you money

How an Extreme Bearing saves you money
Everyone loves a bargain. So when a customer buys a new bearing unit, they often pay extreme attention to the purchase price, especially if they work in procurement. This can be misleading when the real cost of running and maintaining the equipment where the bearing unit will be installed actually determines how much a bearing will cost your company in the long run.

Case Studies

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. Experience has shown that a normal bearing lasts three months, while the Extreme Bearing lasts for years.
You don’t get much more extreme conditions than this. A common design feature of German incinerators is to let the glowing embers and ashes fall into a tank of water below and be extinguished. The ash is then transported up and out of the water on a conveyor belt. The Extreme Bearing shown here is submerged in boiling hot water while hot ash and embers are floating around. Normal bearings usually failed within weeks or months but the Extreme Bearing is expected to last for years.
The Asco Viking Harvester barge has two conveyor belts, one of which is constantly submerged, and a special machine that holds a sack of seaweed weighing up to 2 tonnes. Bearings on such machines and the conveyors need to withstand a great deal of stress, impact, seawater, sunlight, frost and heat. The Icelandic company Asco Harvester started using Extreme Bearings in 2016. Before they had installed bearings with plastic housings but replaced them all in 2017. Read more
“Normal bearings usually need to be replaced on an automatic car wash conveyor every 3-6 months. But with an Extreme Bearing, we believe no maintenance of the bearing will be needed for 8-10 years,” claims Martin Metterhausen, managing director of Wälz- und Gelenklager Lüneburg in Germany, an agent and distributor for Extreme Bearing. A German company has become the first to offer customers the option of fitting Extreme Bearings onto a car wash system.
