HIGH PRECISION MACHINE TOOL BEARINGS
Precision machine tool bearings are mainly
used in the main-shaft of machine tool, motor spindles, ball screw, rotary
tables, etc. Precision angular contact ball bearings can reach P4 A class of rotational accuracy, and
precision cylindrical roller bearings can reach SP, UP class. Due to using optimization
advanced configuration, special materials of rolling elements and cages, our
products have characters of high precision, high speed, low vibration, long
service life, etc.
1.High precision standard angular contact
ball bearings
·Meet ISO
and ZXZ quality standard, accuracy class
reach P5, P4, P4A.
·Products of
71800, 71900, 7000, 7200 series.
·Contact angle
is 15° A), 25° AC).
·Two kinds of
cages selected according to the application, which are phenolic resin cage with
outer rings centered and engineering plastics with rolling element centered.
2.High precision sealed angular contact ball
bearings
·Specific
designed for high speed rotation, low temperature rise, and maintenance-free.
·Contact
angular is 15° A), 25° AC); And special customized design.
·Choose
ceramic ball or steel ball as needed.
·Special
high-temperature resistant rubber seal ring, filled with the grease which is
suitable for ultrahigh speed.
3.Hybrid ceramic rolling element bearings
·Specific
designed for high speed, corrosion resistance, high or low temperature, and
lubrication on the demanding conditions.
·Advantages
with low temperature rise, high rigidity, and long life.
·Rolling
elements with high abrasion resistance that made from special ceramic
materials.
4.Ultrahigh speed angular contact ball
bearings
·High
performance products developed for the application of high speed rotation, low
temperature rise, super precision machining.
·Contact angle
is 15°. Choose steel balls or ceramic
balls, and design to deal with ultrahigh-speed application of dmn value 2
million or more.
·Products of
71800, 71900, 7000, 7200 and other series.
5.High precision matched angular contact ball
bearings
·Matched
angular contact ball bearings, including double, triple, multi-row, and other
various arrangement forms.
·According the
standard, ZXZ completed matching of the
bore diameter, outside diameter, contact angles, projection etc. Before
delivery, bearings can install and used directly by clients.
·The related
dimension tolerance of universal matching bearing shall be controlled by 1/3 of
standard bearings.
6.High stiffness of double row cylindrical
roller bearings
·Applied for
CNC controlled machine tools main-shaft with high speed, high rigidity and high
precision.
·Cages are
made from brass, engineering plastics, PPS(Polyphenylene sulfide),PEEK(polyetherether
ketone)etc.
·Outer ring
has Uniform circular oil hole for lubrication, the standard tapered bore
design.
·Roller
elements can adopt ceramic materials for high speed application.
7.High precision single row tapered roller
bearings
·Can bear both
of radial and axial load, has great load capacity and high stiffness.
·Tapered
roller bearings are separable bearings, so the cup and crown be used
interchangeably.
·Optimizing
the design of raceway, roller and rib shape, suitable for the relatively high
speed.
·Two types
dimensions: metric and inch.
