HIGH SPEED DRILLING MAKES NEW DEMANDS ON BAKU BEARING PLANT;
MOSCOW PLANT SHORTENS TIME FOR MACHINING BFAARTNG RACES
BAKU PLANT SUPPLIES BEARINGS FOR DRILLING MACHINERY -- Baku, Bakinskiy
xabochiy, 8 Feb 51
The Baku State Bearing Plant, which makes precision roller bearings, was
built in the pos..war period and is the first roller bearing plant in Azerbayd-
zhan. Its shops are equipped with new machine tools, powerful. forging and heat-
treating equipment, and control and measuring apparatus. Many processes have
been made automatic.
The putting into operation of the Baku State Bearing Plant strengthened
a weak link in republic petroleum-.machine building for high-speed drilling has
put heavy demands on the products of the bearing ',ndustry. This plant special-
izes in the production of several types of large-size bearings, including sup-
porting bearings for swivels, which must bear an enormous load. Drillers are
increasing the speed of sinking petroleum wells, are penetrating deeper and
deeper into the petroleum bearing strata, and bearing manufacturers should not
hold them back. Their task is to assure high wear resistance of bearings under
ever increasing loads and speed of rotation.
Many machine-building enterprises of the Soviet Union which produce dri.21-
ing equipment, including the Uralmashzavod (Ural Machine Building Plant), now
receive bearings from the Baku State Bearing Plant.
Plant workers have mastered the operation of the highly productive machine
tools and aggregates with which the plant is equipped. There was no place in
Baku where the workers could pick up the specific technical experience neces-
sary for. the manufacture of bearings; nevertheless, personnel capable of direct-
ing complex technological processes and working to the high standard of accuracy
required were trained in a short time,. The plant sent workers to other bearing
plants to study under experienced bearing workers. In turn, experienced engi-
neers, foremen, and Stakhanovites came from these enterprises to teach the per-
sonnel of the young plant.

As personnel were trained and the plant's productive capacity increased,
the plan was filled and exceeded. Last year, the annual program for all re-
quired types of parts was fulfilled on 28 December. Output for 1950 grew 32
percent as compared to 1949, not by the acquisition of new equipment or work-
ers, but by the application of progressive machining methods which sharply in-
creased labor productivity. Labor productivity in 1950 equaled 238 percent
of the 1946 level. Lately, the plant has been trying to increase the volume
of production per unit of existing equipment.
Labor productivity has been increased by high-speed machining of bearing
races on lathes equipped with titanium-cobalt alloy tools. Lathe operators
have increased the speed of machining steel articles to 100 meters per minute.
To save the machine-tool operator time spent on auxiliary operations, technol-
ogists and designers equipped machine tools with chucks having pneumatic grips,
sharply increasing labor productivity of lathe operators. Conveyance of heavy
parts is now mechanized by telphers. Annealing of bearing races is completely

control. Introduction ofan~electric annealing furnace raised the quality and
output of bearing races. Highly productive automatic machines are now being
used to make bearing rollers, and diamondless truing of grinding wheels has
been adopted.
In 1947, it took 28 hours to make a large bearing; now it takes 11 hours.
It formerly took 18 hours to make smaller bearings, now it takes 6 hours.
Every stage in the machining of bearing parts is checked. Bearing plants
accu-
dibpODe of a great number of control and ri inst. ents of extreme
racy, since the tolerance on bearing parts ^is~within ~hundredths of~a millimeter
and control must be very accurate.
Z. Rzayeva, a design engineer in the plant's technical department, developed
an attachment for diamondless truing of grinding wheels, thus decreasing the con-
sumption of costly materials. He has also designed an extremely accurate measur-
ing instrument capable of automatically controlling the dimensions of a bearing
part while it is being machined.
The growth of the bearing output)on the basis of the 1946 level, is shown
as follows (in percent): 1946, 100; 1947, 277; 1948, 485; 1949, 622; 1950, 826
percent.
DRILLMRS 4'A1.1T BETTER SUPPORTING BEARINGS FC.R SWIVELS -- Baku, Bakinskiy Rabochiy,
8 Feb 51
The putting into operation of the Baku State Bearing Plant was a major event
for drilling workers of the Azerbaydzhan petroleum industry, for bearings are ,
needed by the p? anti: which build and carry on caoi,tal.r-pair of drilling equip
ment. There is algo,a great , demand for e?pere baaoings by drilling offices.
The plant is now satisfying this demand, making sufficient quantities of large-
size roller bearings for rigging the basic units of drilling equipment, swivels,
tackle systems, and sludge pumps. The quality of the plant's products has shown
noticeable improvement lately.
Transmission shaft bearings for sludge pumps made by the plant have proved
durable in operation. Their mass production has enabled the Machine-Building
Plant imeni Stalin of the Azneftemash (Azerbaydzhan Petroleum-Machine Building)
Trust and the machine shops of the drilling office greatly to increase sludge
pump renovation. This new source of tackle system bearings has enabled Baku pe-
troleum-machine building plants to expedite the production of crown and tackle.
blocks so necessary to drillers, but there are still occasions when the plant puts
out bearings of this type with slight deviations from the dimensions indicated in
the plans.

The drillers make special demands of supporting bearings for swivels,
both in wear resistance under heavy loads and in design. The 740-type roller
bearing which the plant now manufactures for swivel supports has demonstrated
-its durability. It dupports loads of more than 130 tons, that is, within the
limits of the depths to which shafts are now sunk in Azerhaydzhan. The design
characteristics of such a bearing are another matter. When the swivel is turn-
inb up to 200 revolutions 1;??r minute, the 740-type bearing operates satisfac-
torily. However, technical progress in drilling has mane it possible to in-
crease the speed of rotation of the rotor and the swivel connected to it to
more than 400 revolutions per minute.
Rapid-drilling foremen in Buzovny and other rayons of Apsheronskiy sink
shafts with the drilling tool ro:.ating at 420 revolutions per minute. The 740-
type support bearings made by the Baku State Bearing :.'last do not sustain pro-
longed operation. Moreover, 420 revolutions per minute is not a final limit,
for drilling innovators are constantly finding ways to increase rctation speed.
Increasing this speed requirco new, {improved equipment, part cnlarly support
bearings capable of protracted operation in the swivel at rotation speeds over
400 revolutions per minute. The drillers expect the Baku State Bearing Plant
to produce the parts necessary for rapid drillir. of petroleum wells in the very
near future.
The Machine-Building Plant imeni Lieutenanit Shmidt, which holds the Order
of Lenin, has developed the completely modern, high-quality Sh-V-'4-type swivel,
a part of the powerful forced drilling aggregate. This swivel must be equipped
with a bearing capable of operating under heavy loads and at high rotation speeds.
That is the most important task wick confronts the .u State Becr:ng W.'+
?a
Relations between drilling workers and bearing plant personnel must be im-
proved. Drilling innovators, Stakhanovites, engineers, and drilling office me-
chanics can give bearing workers many valuable suggestions. In turn, this mu-
tual association will aid drillers to conserve equipment and improve their use
of it. -- Sh. Akhmedov, director of the Kirovneft (Kirov Petroleum) Trust Drill-
ing Office.
USES CONTINUOUS METHOD TO MACHINE BEARING RACES -- Moscow; Znaniye-Sila, No 2,

Adoption of the continuous method of production at the Moscow First State
Bearing Plant has shortened the time requ!red for machining bearing races from
10 to 2 days.
