Spindle Bearing Of
Precision Machine Tool
LYC has
developed many kinds of the bearings for the
spindle of precision machine tools in different
tolerance classes, ranging primary from the
NN3000K and NNV4900K double-row cylinder roller
bearing; 3000, 3000 and 35000, 35000R single and
double-row adapter bearing, B7000C bearing for
spindle of the high-speed motor, to
double-united, multi-united double-row thrust
angular contact pedestal bearing. Among these
bearings, B3-706 and B3-707 single-row adapter
bearing for the spindle of precision coordinate
boring machine have been rewarded with gold
medal from state. They have filled in the gaps
in the fields of science and technology in China
and attained the advanced world level of the
same kinds of foreign products; The C946122JY
three-row thrust angular contact pedestal ball
bearing has received the technology advancement
second-class prize from the Ministry of Machine
Building. |

Railway
Bearing
The
bearings for the regular speed passenger train
have been appraised to be the state high-class
product. As for the bearings for the quasi-high
speed passenger car developed and produced by
LYC, all of its performances have met the
technical requirements of the Ministry of
Railway, and its temperature-rise in service is
equivalent to that of NSK bearing. The bearing
for the quasi-high speed passenger car developed
and produced by LYC can sustain the speed of
160-200 km/hour. Its life lasts 3.5-4 million
kilometers, and the reliability of its life at
800 thousand kilometer can be more than 99%,
attaining the advanced world level of the same
kinds of products. The quasi-high speed railway
bearing has been approved as "Nationnal Major
New Product" by State Economy And Trade
Committee.
It won the honor of the "new high-technology
product" from Henan Provincial government.

of bearings for rolling mills. Among these,
bearings for Model 1700 rolling mills imported
by Wuhan Steelworks and Shanghai Baoshan
Steelworks have attained the advanced world
levels, achieved the same level of similar
products made in Germany and Japan. The four-row
adapter bearing, developed and used in the
supporting roller of the surface-finish machine
for Panzhihua Steelworks, has embodied the
world's general developing trend of the bearings
for rolling mills. This bearing also brings in
foreign exchange by exporting to foreign
markets. |

Bearing For Petrochemical And Hydroelectric
Industries
The
bearings as accessories for the No. 4 machine
that LYC developed for the previous Second
Ministry of Machine Building, was awarded a
joint prize from the previous first and second
Ministries of Mechanical Building. The bearing
as accessories for ZGM-95 coal grinder machine
filled in the gab in the fields of science and
technology of China. LYC has successfully made
the necessary accessories for the gates of the
Longyangxia and the Xiaolangdi water conservancy
hinge works. Of the products for these two water
control projects, which the bearings are adopted
with the spaecial design and special treatment
in process. Foreign contractors, after careful
testing and examination, considered the bearings
to have achieved SKF level. |

Slewing Bearing
LYC
is capable to design and produce any kinds of
slewing bearings sized over than 6000 mm,
especially the various kinds of the no-gear,
internal gear and external gear
four-point-contact ball bearings in any
tolerance classes, the double-row thrust angular
contact trust ball bearings, the three-row
composed cylinderical roller bearings, the cross
cylinderical roller bearings and the other
series of slewing bearings etc. They are widely
used in the fields of ports, metallurgy, mine,
food, coal, cement, wind-power generation,
engineering mechanism and etc. At present, the
extra large slewing bearings with the biggest
dimension, heaviest weight, highest precision in
China are all produced by LYC. The dozens of
slewing bearings have been awarded the
technology prizes from State, Province and
Ministries. |
