unit bearing assembly with spherical outside surface is a kind of bearings unit combined the rolling bearings with bearing
housing. Most of unit bearing assembly with spherical outside surface outer diameter are made into spherical form and mounted with housing with shperical bore. Unit bearing assembly with
spherical outside surface has various structures and good universality.

In addition, It is self-aligning in a certain degree, easy to mount, and have double seal setting, they can work in bad environment. The housing is formed by fouding. They
common ones are plummer block housing(P), square housing(F), lug boss square housing(FS), lug boss round housing(FC), rhombus housing (FL), Annular seat(C),slider housing(T) and so on..

Needle roller and cage assemblies are single or double row units comprising cages and needle rollers.
Since their radial section is no greater than the diameter of the needle rollers, needle roller and cage assemblies allow bearing arrangements with a very small radial design envelope to be achieved.
They have very high load carrying capacity, are suitable for high speeds and can be easily fitted.

Housing locating washers are produced by machining, the outside surface is ground and the running surface is high precision machined. They are housing located and are combined with axial cage
assemblies if the adjacent surface cannot be used as a raceway.

Shaft locating washers are produced by machining, the bore is ground and the running surface is high precision machined. They are shaft located and are combined with axial cage assemblies if the
adjacent surface cannot be used as a raceway.

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.

Axial cylindrical roller and cage assemblies comprise axial cages with one or two rows of cylindrical rollers. The cage assemblies have particularly small axial section height, high load carrying
capacity and high rigidity. They can support axial force from one direction and act as non-locating bearings in a radial direction. Axial cage assemblies are combined with housing or shaft locating
washers or are integrated directly in the adjacent construction. If they are used without axial bearing washers, the raceway must be produced as a rolling bearing raceway.

Bearing washers can be used as housing and shaft locating washers. The bore and outside surface are turned, the running surface is ground.

UBC can produce the following rolling bearing accessories such as bearing housing, adapter sleeve and adapter bush, withdrawl bush, locknut and
lock device.

Vertical bearing unit are constituted by vertical bearing housing and self-aligning ball bearings or spherical roller bearings. NACHI has
improved vertical bearing housing in precision, strength, rigidity and other aspects. The followings are the design features of NACHI bearing
housing:
a many size and structure choices are available

b Low weight strength ratio

c The adapter sleeve, straight shaft and the bearings with tapered bore can be installed in any places on the shaft

d The multidiameter shaft and bearings wigh cylindrical bore can be set by bolt on the shaft.

NACHI vertical bearing housings are made of grey cast iron FC200, but ductile cast iron FCD450 or carbon steel SC450 will be used in the
conditions of vibration, shock and overload.
