 MOVING THE WORLD

50 years ago, a dream led to what is today a movement; a movement called

KG International that is going strong-based on the beliefs, principals and
ethics of the founding Chairman Mr. Kedar Gupta who founded the business
in India way back in 1968.

The tiny acorn that germinated from an idea, a potential foreseen, is today
a mighty oak in the shape of KG International of Jebel Ali Free Zone, Dubai.
Sprawling over 55 countries in 5 continents, with a team size of over 100;
KGI believes in forging relationships that last.

It has taken passion, determination, steely resolve and belief to create this
reality, to make KGI a company favoured the world over for its quality,
reliability, customer centricity and range on offer.

Double Row Deep Groove Ball Bearings Single Row Series: 6000

It is correspond in design to single row deep groove ball bearings. They have deep
uninterrupted raceways and high conformity between the balls and raceways. They are
able to carry axial loads acting in both directions in addition to radial loads.

Double row deep groove ball bearings are very suitable for bearing arrangements
where the load carrying capacity of a single row bearing is inadequate. For the same
outside and bore diameters, double row bearings are slightly wider than single row
bearings but have considerably higher load carrying capacity than single row bearings Principal

 Four Point contact
Ball Bearings

Four Point contact Four-point contact ball bearings are

radial single row angular contact ball

Ball Bearings
bearings with raceways are designed to
support axial loads in both directions
and for a given axial load, a limited
radial load can be supported.

 Four Point contact Ball Bearings
Four point contact ball bearing consist of solid outer rings,
split inner rings and ball and cage assemblies with cages.

Due to the two-piece inner rings, a large number of balls can

be accommodated. The halves of the inner ring are matched
to the specific bearing and must not be interchanged with
another bearings of the same size. The outer ring with the
ball and cage assembly can be fitted separately from the
halves of the inner ring.

Therefore, the bearings are self-aligning and insensitive to
misalignment of the shaft relative to the housing, which can
be caused, for example, by shaft deflection. Spherical roller
bearings are designed to accommodate heavy radial loads, as MB design
well as heavy axial loads in both directions. These bearing have fixed rib and machined cages guided on the inner ring rib. KG
can offer this design bearings upon request.

Spherical Roller Bearings are

• Capable of carrying both radial loads and axial loads

• Suitable for low and medium speed applications
• Suitable for applications where some mis-alignment of Shaft
can arise KG can offer following variants
• Single Row type - 202 series (details available on request)

Spherical Plain Bearings

Spherical Plain Bearings (also known as “Spherical Plain Bearings” “Spherical Ball Bushing
Bearings” and “Ball Bushings”) have an inner ring with a sphere convex outside surface
and an outer ring with a correspondingly sphere, but concave inside surface. Their
design makes them particularly suitable for bearing arrangements where alignment
movements between shaft and housing have to accommodate, or where oscillating or
recurrent tilting movements must be permitted at relatively slow sliding speeds.

 Thrust Ball Bearings
Thrust Ball Bearings are separable axial bearings that are produced in both
single and double direction acting design. To assist in simple effective
mounting or dismounting the bearing washers, seating’s, and cage and ball
assemblies, may be individually mounted in their arrangement location.

Thrust ball bearings may accommodate comparatively high axial loads but
they must not be exposed to any radial forces.

Thrust ball bearings are only suitable for low to medium operating speeds,
they require minimum axial loads for their optimum function.

Since thrust ball bearings do not compensate any misalignment, they are
Thrust Ball Bearings are
also frequently used in conjunction with sphered housing washers and
seating washers. • Capable of carrying only axial loads in one direction or two-directions

Single direction thrust ball bearings consist of a shaft washer, a housing

washer and a ball and cage (thrust assembly figure a and b of next page). KG can offer following variants

Spherical Roller Bearings

These bearings are able to accommodate axial loads in one direction only.
• Single Direction Thrust Ball Bearing - 511, 512, 513 and 514
Single direction thrust ball bearings of series 511, 512, 513 and 514 have plain
• Double Direction Thrust Ball Bearing - 522, 523 and 524
(figure a) and sphered housing (figure b).
• Single Direction with Spherical Housing Washer - 532,533 and 534
Double direction thrust ball bearings are suitable to guide the shaft in both
directions (see figure d and e of next page). These bearings consist of
two washers, two ball and cage thrust assemblies with one common shaft
washer located centrally in between. Double direction thrust ball bearings
are also available in both designs, with flat housing washers (figure d) and
sphered housing washers (figure e).

Plummber Block Housings help to form

Plummber Blocks
Bearing units, with Self-aligning Ball
Bearings & Spherical Roller Bearings.
They permit flexibility in the choice

of Bearing, location on Shaft, Seals &
lubrication. Made on modular principle
using Cast Iron HT 200 JIS 5501, KG
Housings are available in a wide range
of sizes to suit various application

Plummber Blocks Housings Series: SN 200
To allow slight adjustment in the position, KG Plummber Block Housings have
two elongated holes for attachment bolts. The Bearing seat in the Housing bore
is designed for non-locating Bearing arrangements. Bearing can move slightly in
either direction to compensate Shaft elongation, which may happen due to thermal
expansion.

Different housing variants and seal designs are available, making the use of tailored
housings virtually unnecessary and enabling cost effective bearing arrangements to
be made.

Generally Bearings used in the Plummber Blocks are lubricated with grease, and since
it lasts for a longer time, Plummber Blocks do not have re-lubrication holes. However, 25 165 40 75 SN 205 1.1

Withdrawal sleeve

To mount bearings with a tapered bore on the cylindrical seat of

stepped shafts The sleeve is pressed into the bore of the bearing
inner ring, which abuts a shaft shoulder or similar fixed component.
The sleeve is located on the shaft by a *nut or an *end plate.

*Note: Nut or end plate are not supplied along with the sleeve.
