Do you know the classification of automotive bearings?
1、 Single row tapered roller bearings
The inner and outer rings can be installed separately;
Rear wheels that can be used for drum brakes (such as Santana rear wheels);
Has higher load-bearing capacity and relatively lower rotational speed;
Small installation space, easy to install;
2、 First generation wheel hub bearings
Fixed and pre-set bearing clearance;
Lifetime lubrication, maintenance free;
Permanent sealing;
Sealing rings are divided into rubber oil rings and combination oil seals;
Compact structure;
3、 Second generation wheel hub unit
The second generation wheel hub bearings combine the economic advantages of the first generation and integrate a wheel hub flange for installing brake discs and wheel rims. The second generation wheel hub bearings are compact bearing units with fixed pre-set bearing clearances, lifetime lubrication (maintenance free), and sealing.
Integrated with a hub flange;
A certain pre-set bearing clearance, integrated with hub flange;
Rolling flanging technology, fully pre tightened;
The snap ring provides axial tension on the outer ring of the bearing and firmly fixes the bearing;
Multiple sensors can be integrated into the sealing ring to support ABS (anti lock braking system), ASR (anti slip device), and ESP (electronic stability system);
4、 Third generation wheel hub unit
The third-generation hub bearings are highly integrated hub bearing units with a mounting flange for installing brake discs and a flange for installing steering knuckles to ensure maximum operational accuracy. The integrated speed decoder provides the signals required for ABS/ESP suspension control. The tightening force of the wheel hub bearing is exerted and adjusted through the annular protrusion.
Compact structure, high bearing capacity, lifelong lubrication, and sealing;
Reduced shaking, improving driving comfort;
High precision brake discs and wheel guidance;
Double flange design, installation does not require adjusting bearing clearance, making installation more convenient;
Higher reliability and longer service life.
