application of tapered roller bearing in wheel hub

application of tapered roller bearing in wheel hub:

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.

XCC specialized in the fields of bearings, bearing parts and auto parts manufacturing.

precision tapered roller bearings :

APPLICATION FEATURES

1. Operation of bearing inner ring;

2. Sometimes, aluminum scrap will enter the bearing inside gearbox;

3. Has a high load carrying capacity, and is able to withstand a certain degree

of axial impact load. Need to ensure the service life of bearings under a high

load;

4. Initially, bearings lubricated by grease, and later use oil to lubricate. Sealing

performance requirements are relatively not very high, but not allow iron and

aluminum scrap entering bearings.

PERFORMANCE:

1. The service life is relatively high under high loads, general requirements of 3~5 times theory life;

2. In the gearbox, foreign matters can enter bearings easily, require bearings have a high compressive strength and wear resistance.

ADVANTAGE

To ensure the service life, we have made improvements in the following two aspects:

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. The bearing rings are manufactured by high speed forging +cold rolling, and do Nitrocarburizing on the raceway surface.

Design Structures:

1. Sealed with tri-lips light contact structure -- having a high sealing performance, and suitable for high-speed operation;

2. Using oil reservoir structured cages -- 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. Both inner and outer bearing rings of high-emission vehicles are used forging process or nitriding treatment -- increase raceway strength, improve crush resistance, and abrasion resistance.
