EXF 4-bolt flange bearing units
316 stainless steel 4-bolt flange bearing
This 4-bolt flange unit can be used in applications where ample space is provided for mounting the housing. The four bolts provide substantial mounting security for high load applications.
Because the housing is made of stainless steel (grade 316), it is rustproof and resistant to corrosion from seawater. It is also resistant to all cleaning products and chemicals. Because the rounded corners and smooth surfaces these units are very easy to clean.
Spherical roller bearing insert
The units are delivered complete with a spherical roller bearing insert that enables the bearing block to carry up to five times more load than conventional bearings. Spherical roller bearings have the advantage that they provide a much larger load capacity than ball bearings and can accommodate axial force.
Many sealing options are possible. Each possesses different properties depending on the application. We would be pleased to advise you on the best choice of seal.

316 stainless steel 4-bolt flange bearing loads
Extreme Bearing units are intended for loads acting vertically towards the base plate support. Therefore, if the bearing housing is supported over its entire base, loads are limited only by the load limits of the bearing insert.
But if loads acting in other directions occur or if the housing is not supported over its entire base area, check that the magnitude of the load is permissible for the bolt assembly attached to the machine frame.
