The QIBR thrust ball bearing consists of two rings with groove and a steel ball assembly that is combined with a cage.

Advantages: The product structure is simple and easy to use.

Disadvantages: It can only withstand axial loads and cannot withstand radial loads.

Under axial load, the ball rolling along the bottom of the groove because of it subjected to axial force. Therefore, the limit rotation speed of the thrust ball bearing is low, it is suitable to use when the radial bearing cannot withstand excessive axial load.

Main structure type: one-way thrust ball, two-way thrust ball

Basically thrust ball bearings are consists of four parts housing washer, shaft washer, balls and cage. The outer dimensions of QIBR thrust ball bearings conform to GB/T 301-1995 "Dimensions of rolling bearing thrust ball bearings".

Main structure type:

1.One way thrust ball bearing 51000 type, follow figure 1, figure 2.

2.Two way thrust ball bearing 52000 type, follow figure 3.

Figure 1 one way thrust ball bearing

Figure 2 one way thrust ball bearing with outer cover

Figure 3 two way thrust ball bearing

One-way thrust ball bearings can only withstand axial forces in one direction. Two-way thrust ball bearings have two housing washer, two steel balls and cage assemblies, and spacers can withstand two-way axial forces.

QIBR thrust ball bearings are available on one-way thrust angular contact ball bearings as shown below

One way thrust angular contact ball bearing

The one-way thrust angular contact ball bearing mainly bears axial load, can bear a small amount of radial load, and can also accept high limit rotation speed. The contact angle is mainly 45° and 60°, which is suitable for combination loads that axial load as priors with a certain radial load.

QIBR customization non-standard thrust ball bearing

Non-standard thrust ball bearing customization is a main part of QIBR categories, we can provide thrust ball bearings with other structure type according to customer request, for example full complement thrust ball bearing that steel balls without cage, tapered bore one way thrust ball bearing, wire raceway one way thrust ball bearing etc., as mentioned in the article, the contact angle can also be customized based on customer requirement, and at the same time, non-standard thrust ball bearings can be designed according to the actual working conditions of customer.

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.
