XCC 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.
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 equipments, ZXZ has ability to service for world class level customers.
Tensioner Bearings:
APPLICATION FEATURES
1. High-speed running of bearing outer ring;
2. Temperature of operating environment above 100 ℃;
3. Surrounding of bearings with water vapor, dust;
4. Contact with mud frequently;
5. Use in high-temperature and alpine region;
6. High rotation speed;
7. Operate of belt transmission; the rotation speed of bearings change frequently
during operation; force direction changes with belt swing; magnitude of load
changes frequently -- hearings have a greater impact of variable speed and
variable load.
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.

PERFORMANCE
1. High requirement of sealing performance:not allow water vapor, dust, etc.
leaking into the bearing;
2. High requirement of high-speed operation performance;
3. Excellent thermal stability at -40 ℃ ~ 150 ℃;
4. Starting torque:normally select medium contact seals;
5. Long service life:in accordance with the requirements of Automotive Bearings,
testing life required more than 500h.
ADVANTAGE
The material selection of bearing components:
1. Rings manufactured by high-purity specialty quality bearing steel;
2. Steel balls are from famous brand manufactures, 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 (thickening agent) Grease.
Design Structures:
1. Sealed with tri-lips medium contact structure
-- having a high sealing performance, and suitable for high-speed operation;
2. Using engineering plastic 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
-- adapt to high-speed performance and axial movement requirements.
