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.

Housing materials and outer surfaces |

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 ╳ See Lubricant Grease cartridge Fatty acids and the initial grease ╳ See Lubricant Grease cartridge 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 ╳ See Lubricant Grease cartridge Fatty acids is allowed to escape.

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.

Locating and non-locating bearings |
|
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.

Sealing |
|
Bearing
housings can be sealed, depending on the operating conditions,
by the use of contact seals, non-contact seals ╳ Elements intended to prevent the ingress of gaseous, fluid and solid materials through the gaps formed by adjacent components whilst stationary or moving.
See Seal Operating life Friction or combinations
thereof, Figure 1 to Figure 3.

All
flanged housings have a threaded hole M10×1 that is closed
off by a plastic plug until relubrication is to be carried out.

These
flanged housings are suitable for self-aligning ball bearings, barrel
roller bearings and spherical roller bearings with a tapered bore
that are located on the shaft using adapter ╳ An accessory mounted on another element, for example a lubrication adapter sleeves. The housings are
available with one side closed off (design A)
or – for
continuous shafts – open on both sides (design B). Felt strips are
used for sealing. Felt seals ╳ Elements intended to prevent the ingress of gaseous, fluid and solid materials through the gaps formed by adjacent components whilst stationary or moving.

The
housings are designed as non-locating bearing ╳ Non-locating bearings of the longitudinal, transverse or tilting type permit displacement within the bearing requiring almost no force housings. Locating
bearing arrangements can be achieved by the insertion of locating rings.
The number of rings required is indicated in the tables. Two rings are inserted
on both sides of the bearing, a single ring is inserted on the
side with the adapter ╳ An accessory mounted on another element, for example a lubrication adapter sleeve nut. Locating rings must be ordered
separately.
