DescriptionXCC Group is China listed group enterprise (stock
code: 603667) with more than 10 subsidiaries, specialized in the
fields of bearings, bearing parts and auto parts manufacturing.XCC
has an integrated bearing production chain what combined with
R&D, tubing, forging, turning, heat treating, grinding
etc. Including auto alternator bearings,tension bearings,
air-conditioner clutch bearings, water pump bearings, precision
machine tool bearings, chemical fiber & textile machinery bearings,
as well as whole series of standard and non-standard deep groove
ball bearings etc with high precision, high speed, low
noise and long life.ZXZ build up entire bearing production line
from steel tube, forging, turning, heat treatment to grinding and
assembling after 10 years effort; high quality bearing rings which
do heat treatment already provide for top 5 bearing manufacturer
worldwide, production capacity reach 200 million sets annually;
adopt full automatic CNC grinding and assembly line, benefit from
big amount of advanced manufacturing equipment, ZXZ has ability to
service for world class level customers.ZXZ AUTOMOTIVE SERIES
BEARINGSTo adapt the development thread of automotive accessory
products with dedicated, customized and unitized, we combined
characteristics of automotive products, focus on research and
development of automotive bearings and related parts, hub
bearings, tension bearings, clutch release bearings, steering
bearing, water pump bearings (WB series, WR series), vane pump
retaining ring, spherical roller, cam blocks, and other auto
parts.ADVANTAGE:1. Long life: Fatigue life, Lubrication life,
Sealing life.2. High speed performance;3. High sealing capacity;4.
Excellent high & low temperature working condition;5. Low starting
torque;6. Creep resistance.DESIGN STRUCTURE1. INNER RING, OUTER
RING, STEEL BALL: Bearing rings manufactured with high purity
special bearing quality steel;2. CAGE: Glass fibre reinforced
polyamide cage;3. SEALING RINGS: 1. Inner rings with V-shaped
groove; 2.Seal ring with triple-lip contact design4. GREASE:
Synthetic oil (base oil)+Polturea-based (thickener) grease;5. OD
with expansion nylon ring or "O" shaped rubber ringZXZ alternator
bearings for automobileAlternator BearingsApplication:1. High-speed
running of bearings inner ring;2.Temperature of operating
environment above 120ºC;3. Surrounding of bearings with water
vapor,dust;4. Contact with mud some times;5. Soak in water in
special time;6. Use in high-temperature and alpine region;7. High
requirement of limiting speed;8. Operate inside a magnetic field,
prone to have white flaking;9. Can withstand operating conditions
both of rapid acceleration and rapid
deceleration.Performance:1. The sealing performance
requirements; do not allow water, vapor or dust leak into
bearings;2. Bearing requirements of high performance
high speed;3. High and low working temperature from
-40ºC to 180ºC;4. Low starting torque; the light
contact seal;5. The use of long life; in accordance
with the requirements of more than 1000h.Advantage:The Material
Selection of Bearings Components;1. Rings adopted
by high-purity specialty quality bearings
steel;2. Steel balls are from famous brand
manufacturers; that effectively guarantee materials and processing
accuracy;3. Using glass fiber reinforced nylon
cages;4. Sealed with high quality acrylic
rubber;5. Using synthetic oil (base oil) +
Polyurea (thichening agent) grease.Design
Structure:1. Sealed with tri-lips light contact
structure-having supper sealing performance, and suitable for
high-speed operation;2. Using engineering
plastics cages with oil reservoir structured-effectively increase
the lubrication capability of bearings;3.
Optimize the groove curvature of outer ring and the raceway of
inner ring-suitable for high-speed and reduce axial
movement;4. Some bearing`s OD with nylon
expansion ring or [O"-type ring-prevent creeping.
