SS-316 Flange, double
roller bearing units
SS-316, 4 hole Flange, double roller bearing.
- 5 times high load capacity
- Chemical resistance
- Very well sealed with labyrinth seals
This EXF 4-bolt flange unit is made for heavy-duty applications and corrosive environments. 5 times high load capacity due to the use of self-aligning double row ball bearings.
Because the housing is made of stainless steel (grade 316), it is rustproof and resistant to corrosion from seawater and chemicals.
Heavy stainless steel 316 roller bearing housings for use in extreme conditions
Extreme bearing housings can be supplied with single or double row spherical roller bearings

Tensioner stud
The EXF bearing unit is provided with a tensioner stud. This is a unique feature of this type of Extreme Bearing. This feature can be very helpful to design a coveyorbelt
Axial load bearing carrying capacity
Double row spherical roller bearings have an extremely high load carrying capacity, tolerating both radial and axial loads in both directions. A standard Extreme Bearing is equipped with this kind of bearing and locked on the shaft by using an adapter sleeve. When occur a axial load on the shaft mounted by a standard Extreme Bearing is the maximum load, the load that can be hold by the adapter sleeve.
Based on practical experience can be made a approximate calculation of the axial load which can be kept by the adapter sleeve, by using the a rule of thumb :
Fap = 0,003 · B · d Fap = maximum permissible axial load, kN B = bearing width, mm d = bearing bore diameter, mm
For heavier axial load
When the Axial force of the standard equipped Extreme Bearing is not high enough, we offer you two more options:
- When the force is coming from the cover side of the bearing unit, we use a CV-Busing in a sphircal roller bearing with cylindrical bore to bring the force straight on the bearing itself.
- When the axial force is coming from the back side fot the bearing unit, we use a DR-ring to bring the force over straight on the bearing itself.
Trust bearing for huge axial loads
When the loads are not sufficiently, please explore the EXV thrust bearing units
The EXV thrust flange thrust bearing unit is a new type of bearing unit from the range Extreme Bearing products. Type EXV thrust bearing units are designed to bear and supports heavy axial loads or loads parallel to the shaft axis. This complements the product range because the EXV bearing blocks go much further in carrying very large axial loads.
