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.

The housing is made of stainless steel (grade 316) which is rustproof and resistant to corrosion from seawater. It is also resistant to all cleaning products and chemicals. The rounded corners and smooth surfaces make these units very easy to clean.

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.

The EXF Extreme Bearing was used below ground level on two shafts of a conveyor belt that moves a car through the various machines of a conveyor tunnel car wash.

Footnotes: T¹ The dimension T gets a maximum 6 millimetres wider when the bearing unit is assembled with centrifugal seals.

316 stainless steel 4-bolt flange bearing

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. 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.

Type EXF 4 bolt flange bearings

Tensioner stud

The EXF bearing unit can be provided with a tensioner stud. In that case, the load can act in the opposite direction to the threaded rod. This is a unique feature of this type of Extreme Bearing.
