Main functions of the QIBR vehicle hub bearing are to bear load and guide accurately the hub rotating. It can bear radical load, also axial load, is a very important component of the vehicle. Currently most popular hub bearings are the second generation and third generation ones.

In which the second generation hub bearing is a double-row angular contact bearing, outer ring with flange working with two inner rings. Main structures of the third generation hub bearing are outer ring with flange, inner ring and shaft washer with flange. There is a flange for fixing bearing at the outer ball race of the second generation hub bearing, which can easily fix the bearing to the wheel axle with nuts and make the vehicle repairing work become easier. The third generation hub bearing unit combines bearing unit and anti-locking braking system (ABS). The vehicle bearing mentioned here mainly refer to car’s hub bearing, commonly like tapered roller bearing, deep groove ball bearing, needle bearing and so on.

Raw material

QIBR precision anti-friction bearings are usually made of chrome steel, which consist of about 1% carbon, 1.5% chromium and a small amount of manganese, silicon, and sometimes a small amount of molybdenum.

QIBR offers you a wide range of material options such as GCr15, 100Cr6, SKF 3, SUJ-2 etc. At the same time, some models of QIBR are available in stainless steel.

The rolling element can be ceramic ball (silicon nitride). Due to ceramic is kind of special material, the ceramic ball bearing has advantages of higher rotation speed, good self-lubricating property, and the rigidity is 15%-20% higher than the general bearing, and better high temperature resistance.

Bearing cage

The high-quality cage used by QIBR bearings ensure that the balls are evenly distributed in the bearing rings and can be rotated properly.

The cage has stamped steel wave type, stamped steel rivet type, nylon or phenolic plastic.

QIBR offers a wide range of advice and options depending on the operating conditions.

Seals

In order to prevent contaminants from entering the inside of the bearing, QIBR uses a metal dust cover or a rubber seal with a metal skeleton.

QIBR are able to choose two types as a combination seals according to your working conditions, or choose different kinds of seal materials, such as nitrile rubber BUNA, acrylic rubber HYCAR, fluoro rubber VITON.

Type of lubrication

Lubricating oil is the basic lubricant for ball bearings. Previously most of the lubricating oil was extracted from petroleum. Synthetic oils are now acceptable due to improved performance, such as two lipid synthetic oils, silicones and fluorocarbon synthetic oils. In general, lipid synthetic oils have better low temperature properties, lower volatility, and better temperature characteristics and viscosity compared than petroleum refined oils. Essentially all lubricants contain additives to inhibit chemical changes, prevent metal corrosion, and improve physical properties (antifoam, etc.).

The silicone and fluorocarbon synthetic oils that adopted by QIBR have lower volatility and wider temperature/viscosity characteristics.

Radial clearance

The radial clearance is the gap between the steel ball and the ring. QIBR is precisely tailored to customer's temperature conditions, interference fit, misalignment of the bearing's axis, required noise level and speed.

Service life and the rated load

The bearing life is the number of bearing rotations before the fatigue occurs on the ring or any rolling element (or the rotation time at a constant speed). However, the same set of bearings will not necessarily have the same life under the same conditions. In this case, the rated life is the number of rotations that 90% of the bearings in this group can reach or exceed before bearing weariness (or the rotation time at a constant speed). The service life of QIBR series bearings are 10%-20% longer than other bearings of the same model, through strict production process, high standard material selection, precision control.

The adopted steel balls

The steel balls in the deep groove ball bearings used by QIBR are mainly designed according to the load requirements of the bearing. The bearing ball sizes of different models are different, generally the value of rib coefficient Kd (ditch depth) range 0.35-0.40. , related to bearing diameter, such as 6000 series Kd = 0.35, 6400 series Kd = 0.40; 6200 and 6300 series, d ≤ 25mm take Kd = 0.35, d > 25mm take Kd = 0.40. Groove depth = Kd × steel ball diameter.
