Bearings for heavy load in harsh environmental !

Inox 316, five times higher load capacity and sealed !

A Extreme Bearing is a stainless steel 316 bearing housing containing a heavily loadable roller bearing allowing it to carry up to 5 times more heavy load side than today’s usual bearing blocks

Extreme Bearings 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.

    Heavy duty

    • For heavy radial loads
    • For combined radial and thrust loads
    • Suitable for expansion and contraction of the shaft
    • 5 times higher load capacity of mounted ball bearings
    • Low friction angular misalignment
    • Suitable for expansion and contraction of the shaft

    Harsh conditions:

    • Washdown, submersible
    • SS 316 has a very high resistance to sea water
    • -40 up to 200 C
    • Resistant to almost all chemicals
    • IP66

    Foodsafe

    • Stainless steel 316
    • Allowed to cleaning with high pressure cleaner in use of aggressive chemicals
    •  Smooth surfaces for maximum clean-ability
    • Made of full material, do not encourage the build-up of dirt
    • HACCP/HARPC compliance
    • Free choice of grease

    Cost effective:

    • Interchange many brands of mounted ball bearings
    • increase equipment up-time
    • Save money by reusing housings through multiple bearing change-outs
    • Covered a wide range of ball bearing units, results in less spare parts

    Customization:

    • Dirt dependent sealing options
    • Load dependent bearing inserts
    • Special housing design on request
    • For heavy vertical loads
    • In-house CAD team are at hand to provide solutions to any of your bearing needs.

    Why Extreme Bearing?

    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 (F) holds the outer ring of the insert firmly in the housing, making it difficult or even impossible to adjust the insert. If the bearings are subject to excessive axial loading, the forces generated penetrate through the bearing, causing damage to the balls, inner ring, ball race and even the housing. Ultimately, the insert has to be replaced, while the bearing housing is also damaged permanently in many cases.

    Extreme Bearing takes a different approach.

    Extreme Bearing does not use a spherical outer ring, but instead has an (optional) double-row ball bearing or roller bearing. The concave raceway of the outer ring in combination with two rows of balls operate over a wide range of contact angles.  it aligns itself correctly with the shaft and assembly without causing undue stress on the rest of the bearing assembly.

    How Extreme Bearings work

    Bearing insert

    Spherical Roller bearings have the advantage that they are self adjustable.

    Extreme Bearing’s spherical roller bearing are made of through hardened inner and outer raceways with single spherical rolling elements separated by steel land riding retainer (cage) and bearing protection shields. Extreme Bearing roller bearings provide for supporting rotating shafts with combination radial and thrust loads.

    Adapter sleeve

    Clever fitting using an adapter sleeve takes away the need for an eccentric clamping ring or allen key, both have been known to cause additional problems. The choice of the used materials contributes to a longer service life and, ultimately, better results and lower costs.

    Triple barrier sealing

    Keeps the elements and unwanted intruders out of the bearing housing.

    1. Primary barrier seals
    2. Grease-filled housing
    3. 2-RS bearing seal

    Not only the small gap between the seal lip and the shaft that provides sealing against contaminants, also The Bearing housing is filled with grease to prevent contaminants from entering and damaging the bearing.

    Axial displacement

    Suitable for expansion and contraction of the shaft

    The seats are machined to a tolerance to provide a loose fit. The bearing seats in the housings are sufficiently wide to allow axial displacement of the bearing and to accommodate for thermal expansion of the shaft due to high temperatures, such as on a baking conveyor belt.

    The Extreme Bearing blocks can absorb expansion of the shaft because there is an adjustment or locating ring in the bearing housing. The locating ring can be removed from a bearing block of a pair placed opposite each other so that axial displacement is possible.
