Classification of automotive bearings

Classification of automotive bearings:

NN30K Series

Single row conical shaft:

◆ The inner ring and outer ring can be installed separately;

◆ Can be used for drum brake rear wheels (such as Santana rear wheels);

◆ It has higher carrying capacity and relatively low speed;

◆ Small installation space, easy to install;

 

First generation bearing:

◆ Fixed, preset bearing clearance;

◆ Lifetime lubrication, maintenance-free;

◆ Permanently sealed;

◆ The sealing ring is divided into: rubber oil ring and combined oil seal;

◆ Compact structure;

Front wheel drive hub and bearing assembly

Second-generation hub unit:

The second generation hub bearing combines the economic advantages of the first generation and integrates a hub flange, which is used to install the brake disc and the wheel flange. The second generation hub bearing is a compact bearing unit with fixed The pre-set bearing clearance is lubricated for life (maintenance free) and sealed.

 

◆ Integrated a hub flange;

◆ A certain pre-set bearing clearance and integrated hub flange;

◆ Rolling flanging technology, fully preloaded;

◆ The snap ring provides the axial pulling force of the outer ring of the bearing and secures the bearing firmly;

◆ Multiple sensors can be integrated in the sealing ring to support ABS (anti-lock braking system), ASR (driving anti-skid device), ESP (electronic stability system);

 

Three-generation wheel hub unit:

The third-generation hub bearing is a highly integrated hub bearing unit with a mounting flange for installing the brake disc and a flange for mounting the steering knuckle to ensure the highest running accuracy. The integrated speed decoder provides the signals required for ABS/ESP suspension control. The tightening force of the hub bearing is actuated and adjusted by the annular boss.

 

◆ Compact structure, high bearing capacity, life-long lubrication and sealing;

◆ Shake is reduced and driving comfort is improved;

◆ High-precision brake disc and wheel guidance;

◆ Double flange design, installation does not need to adjust bearing clearance, installation is more convenient;

◆ Higher life reliability and longer service life;
