FAG housings and the associated bearings form bearing arrangement units that have proved themselves in machinery, plant and other equipment.
FAG bearing housings are predominantly made from flake graphite cast iron. Housings made from cast steel and spheroidal graphite cast iron can be supplied by agreement. Since the bearings are normally lubricated with grease and the initial charge is effective for a long period, most housings do not have relubrication holes. However, gates or marks are present so that lubrication holes can be made if required. When relubrication is carried out, it must be ensured that excess grease can escape.
The bearing seats in the housing are generally machined such that the bearings are movable and can thus act as non-locating bearings. Locating bearing arrangements can be achieved by inserting locating rings if these are listed in the tables. Locating rings must be ordered specifically. Housings without locating rings are supplied in a non-locating bearing version (L) or a locating bearing version (F).
All unmachined outer surfaces of FAG housings and housing parts have a universal coat of paint (colour RAL 7031, bluish grey). The paint can be covered by all resin, polyurethane, acrylic, epoxy resin, chlorine rubber, cellulose and acid-hardening hammer grey enamels. The anti-corrosion protection of the machined inner and outer surfaces can be easily removed.
Depending on the operating conditions, contact seals, non-contact seals and combinations thereof are available for sealing of bearing housings, see the schematics.
