FAG housings and the associated bearings form bearing units that have proven successful in machinery, plant and equipment. It is only possible, however, to show here a small selection of the numerous sizes and designs (for an overview of the FAG series housings, see publication TI WL 90-30). For other housings or housing ╳
See Mounting dimenstions designs, please consult Schaeffler Group Industrial.

The bearing housings are predominantly made from flake graphite ╳
Solid lubricant with layered grid structure. Suitable for dry running or as active ingredient in oils or greases. Graphite absorbs moisture. Graphite displays its best lubrication characteristics in damp environments. cast iron. We can supply housings made from cast steel or spheroidal graphite cast iron by agreement. Since the bearings are generally lubricated with grease ╳

Fatty acids filling lasts for a long period, most housings do not have relubrication holes. However, there are cast-on bosses or marks present so that lubrication holes can be made if necessary. If relubrication is carried out, it must be ensured that excess grease ╳

All outer surfaces ╳
The effective surface is the surface which separates the object from its surrounding medium.The actual surface is the approximate image from measuring technology of the ideal geometric surface. Note: various measuring processes or measuring conditions (e.g. stylus radius) can give different actual surfaces.The geometric surface is an ideal surface whose nominal form is defined by a drawing or other technical documentation. See DIN 4760 for further details.

Surface tension machined by chip-forming methods can be easily removed.

The bearing seats in the housing ╳
See Mounting dimenstions are generally machined such that the bearings are movable and can thus function as non-locating bearings. Locating bearing arrangements can be achieved by the insertion of locating rings if these are listed in the tables. Locating rings must be ordered separately. Housings without locating rings are supplied in a non-locating or locating bearing ╳
Bearing capable of transmitting axial loads from both directions and radial loads design.

Bearing housings can be sealed, depending on the operating conditions, by the use of contact seals, non-contact seals ╳

Non-locating bearings of the longitudinal, transverse or tilting type permit displacement within the bearing requiring almost no force housings.
