QIBR angular contact ball bearings can support radial and axial composite loads, also bear pure axial loads. They have the traditional advantages of ball bearings that high speed, low noise, etc. The greater the contact angle, the higher ability to withstand axial loads. If the axial load increases, the actual contact angle of the angular contact ball bearing will also increase. Single row angular contact ball bearings can only withstand axial loads in one direction.

Angular contact ball bearing is consist of outer ring, inner ring, steel balls, seals and grease, with features that the contact angle between the line connecting the ball and the raceway contact point and the radial plane vertical to the bearing axis line is generally between 0° and 45°. Common angle is 15°, 25°, 40°. According to the number of rows of the steel balls, bearings are divided into single row angular contact ball bearing, double row angular contact bearing etc.

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.


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.

Single row angular contact ball bearing

Double row angular contact ball bearing

Paired mounting angular contact ball bearings

Because single-row angular contact ball bearings can only withstand axial loads in one direction, more occasions in life are used in pairs with single row angular contact ball bearings, or triple, quadruple or even multiple combinations. There are three types of commonly used QIBR angle ball bearings, back-to-back, face-to-face, and tandem arrangement. As shown below

Tandem arrangement angular contact ball bearing

Back-to-back combination angular contact ball bearing

Face-to-face combination angular contact ball bearing

Tandem arrangement: The radial and axial loads are equally shared by the two bearings, and the bearing can only withstand the axial load from one direction, just have stronger axial load capacity compared with a single bearing.

Back-to-back combination: The intersection point of the pressure lines of two single row bearings with axis line is on the outer side of bearing, the distance between the pressure points is increased, with strong rigidity, and are able to withstand the overturning moment and axial force from two directions, the effect is similar to one double row angular contact ball bearing.

Face-to-face combination: The intersection point of the pressure lines of two single row bearings with axis line is on the inner side of bearing, the rigidity is low. It is not suitable to withstanding the overturning moment, but can withstand the axial force in two directions. This form is generally recommended.

Bearings that can be mounted in a matched combination require high precision manufacturing of the bearings, paired bearings and double row angular contact ball bearing code 0.

The classification of non-standard angular contact ball bearings

QIBR are able to provide sealed angular contact ball bearings, angular contact ball bearings with snap grooves on the outer ring, etc. QIBR can make new design for customized bearings according to customer need, such as the bearings with irregular contact angle. As shown below.

Angular contact ball bearings are classified into general dust cap seals, non-contact rubber seals and contact rubber seals. Usually, the sealed bearings are filled with grease lubricant. The amount of grease is 25% to 40% of the effective space of the bearing. If there are special requirements, we can make corresponding adjustments.
