Stainless steel roller bearing units for use in extreme conditions !
Developed to be tough!
The Extreme Bearings are made entirely from high-grade AISI 316 stainless steel. This stainless steel bearing housing is combined with a spherical roller bearing clever sealing options to keep dirt, water and chemicals out.This complete bearing assembly unit is what we call the Extreme Bearing.

Washdown and robuste SS 316 bearing housings for EXTREME BEARING applications!
EXTREME BEARING Washdown Bearing Units are different by all other systems.
Extreme Bearings are made of stainless steel 316, very good sealed and combined with a spherical roller bearing!
To bear heavy loads
Double row spherical roller bearings have an extremely high load carrying capacity tolerating heavy load in radial and axial directions.
- Up to 5 times higher load capacity than conventional bearings
- Specially designed for use on conveyor belts subject to heavy loads
- For combined radial and thrust loads
- Suitable for expansion and contraction of the shaft
- Rotation with low friction, and permits angular misalignment.
To bear in harsh conditions
- Continues to function well in very rough conditions
- High resistance to seawater
- Designed for washdown with high-pressure cleaning jets
- Can be submerged down to 400 metres deep
- Available for temperatures up from -80°C up to 270°C
- For extreme heat or cold. Allowed the thermal expansion and contraction of the shaft
Bear stainless AISI 316
- Extreme Bearing units are resistant to almost all chemicals
- Can be washed down with high-pressure jets and aggressive cleaning agents
- For high hygiene HACCP/HARPC compliance
- Easy-to-clean smooth surfaces
- Made of solid material, so foodsafe, no crevices or spaces for the build-up of dirt
- Very high corrosion resistance
- Stainless steel AISI 316 has a very high resistance to seawater
-
For heavy loads
-
Stainless steel 316
-

Strongest and most resistant bearing units for harsh environments!
With a high-end sealing solution, spherical roller bearings and a bearing housing made of stainless steel 316 are Extreme Bearings very suitable for aggressive environments in combination of heavy loads. Capacity up to 5 times higher load capacity then regular bearing units.
Case Studies
An exceptionally unique Extreme Bearing experience !
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 fail 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.
