Supplier Factory Bearings KOYO DAC40760041/38ZZ Wheel Hub Bearing

Hub bearing is the main role of bearing and provide accurate guidance for the rotation of the hub, it bears both axial load and radial load, is a very important part. The traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of bearings are all carried out on the automobile production line.
This structure makes it difficult to assemble in automobile production plants, high cost, poor reliability, and the car in the maintenance point maintenance, but also need to clean, oiling and adjustment bearings.
Hub bearings are very important part in terms of vehicle safety. Selecting the type of bearing most suited to the vehicle ensures safety and is very important for exhibiting the required performance. To select the best bearing, one must consider and evaluate the bearings from a variety of angles.
Life of hub bearings is calculated by inputting reaction force (radial load and axial load) on the wheel given as set traveling conditions as load. Each bearing is a unit bearing consisting of two rows of bearings. Life of the bearings is calculated separately for the each of the bearings. Bearing life is calculated for the outer and inner bearings.

Advantages of truck hub bearing include:

1.Pre-adjusted for easy installation
2.Lubricated and sealed for extended life
3.Can withstand extreme operating conditions
4.Cost-effective installation process
5.Low maintenance

Working principle:

Truck hub bearings are factory preconditioned, lubricated and sealed to simplify installation. Wheel bearing units are available for trucks, trailers and buses. Wheel bearing units are designed to withstand the typical severe operating conditions and require less maintenance than the traditional wheel bearing sets they replace. Some variants come with an integrated impulse ring, which makes them suitable for anti-lock braking systems. The unit also saves time and money on brake maintenance.
