Precision
angular contact ball bearings are mainly used for high-speed rotating
occasions, such as machine tool spindle, high-speed motor, machine ball
screw, steam turbine, centrifugal separator and so on. Requires high precision bearings, high speed, low temperature vibration and a certain degree of service life. Often used as a high-speed spindle support components used in
pairs, is the surface of the high-speed spindle grinding machine key
components.
So the choice of precision angular contact ball bearings is critical,
he directly affects the processing performance of machine tools, and now
the bearing market mixed, fish, in the selection of precision angular
contact ball bearings need to pay more attention.
A common way to identify bearing quality:
(1)
whether the packaging is clear; under normal circumstances, the factory
brand has its own special design staff to design the external
packaging, and arrange the production conditions of the factory to
produce production, so the packaging from the line to the color blocks
are very clear, Unambiguous, part of the imported brand of accessories on the
packaging there are specifically designed to protect their own unique
intellectual property design.
(2) steel printing is clear: the bearing body will be printed on the brand words, labels and so on. The
font is very small, but most of the products are produced by the use of
stamping technology, and before the heat treatment before the pressure
word, so the font is small, but concave deep, very clear. The counterfeit product font is not only blurred, because the printing
technology is rough, the font floating on the surface, and some even
easily can be wiped out by hand.
(3)
whether there is a noise: left hand holding the bearing sleeve, right
hand toss the jacket to rotate, listen to whether there is a noise. As
most of the counterfeit products production conditions behind,
completely hand-workshop operation, in the production process will
inevitably be mixed with a class of impurities in the sand, hidden in
the bearing body, so when the rotation will be issued a noise. This is the biggest difference between the strict implementation of the production standards and the operation of the machine.
Jintai
focused on precision bearings R & D and manufacturing for 26 years,
mainly for machine tool bearings, spindle bearings, engraving machine
bearings and other areas of the depth of R & D design, product
positioning accuracy in high-precision P4, P2 level, not producing less
than P5 level bearings, Far
more than domestic counterparts, to replace the best choice for
imported bearings, is committed to becoming the first brand of angular
contact ball bearings and efforts to professional technical services for
customers to create value.
