Ball bearings are high-speed bearings compared to roller bearings. The higher the accuracy level, the smoother the rotation at high speed. For users, no matter under what conditions the rolling bearing is used, the customer will definitely prefer the bearing with a higher precision level. However, the higher the precision level of the bearing, the more expensive the price. Then, bearing suppliers should pay attention to some methods to improve the service life of precision ball bearings. The service life of high-speed ball bearings has a lot to do with the installation method. The following are some points to be paid attention to:

1. Precision ball bearings should be installed in a dust-free and clean environment. The bearings should be carefully selected. The spacers used for precision ball bearings should be ground. On the premise of maintaining the same height of the inner and outer rings, the spacers should be parallel. Degree should be controlled below 1um;

2. The high-speed ball bearing should be cleaned before installation. When cleaning, the slope of the inner ring should be upward, and the installation should be flexible without stagnation. After drying, inject the specified amount of grease. If it is oil mist lubrication, a small amount of oil mist oil should be added.

3. Special tools should be used for the installation of ball bearings to ensure uniform force on each part. It is strictly forbidden to knock during the installation process, or it is strictly forbidden to have a large force on a certain part.

4. Ball Bearings should be stored in a clean and ventilated environment with no corrosive gas and relative humidity not exceeding 65%, and precision ball bearings should be regularly rusted for long-term storage.

In addition to the above items, if your ball bearing has any problems during storage and use, please contact us FV Bearings in time.

Angular contact ball bearing is a widely used bearing. Different accuracy grades have different prices. The higher the accuracy, the more expensive the price. If the bearing is damaged, it is necessary to replace the bearing on the one hand, and on the other hand, the shutdown will bring losses. Therefore, it is necessary for users to reduce the loss of bearings. The life of rolling bearings has a certain dispersion even under good operating conditions. For important equipment, especially angular contact ball bearings that work under harsh conditions, whether the angular contact bearings installed in them work reliably and how long they can continue to run has become a special concern for customers. Today, Luoyang FV will talk about how to reduce the damage of angular contact ball bearings.

To reduce bearing damage, some diagnosis is necessary, mainly as follows:

1. Observe the fractured part of the angular contact ball bearing with a high-magnification scanning electron microscope, check whether there are fatigue arcs and a large number of corrosion pits in the crack area, whether there is a fan-shaped pattern, and what the fan-shaped pattern looks like.

2. Check the bearing stress. Bearings are mainly subjected to three kinds of stress: explosion stress, assembly stress and thermal stress. Fire in an angular contact ball bearing is an abnormal phenomenon. Abnormal defects such as burns often seriously affect the appearance quality and product performance of the workpiece, especially for precision workpieces or important workpiece surfaces that require high appearance quality.

3. When induction heating is observed in the production of angular contact bearings, the ignition between the angular contact bearing and the inductor is often not a point contact, and the noise generated by the angular contact ball bearing is very sensitive. Therefore, in order to ensure the smooth operation of angular contact ball bearings, some measures should be taken, such as appropriate control of sintering conditions to make the alloy structure into a single phase, and anti-corrosion process measures can also be taken; another method is to generate compressive stress on the outer surface of the workpiece to prevent the tensile stress in use.

Bearing damage is inevitable. What we need to do is to take some measures as soon as possible when there is a small damage to the bearing, which can effectively alleviate the damage and prolong the service life of the bearing. Welcome to contact us!

Installation Method for Improving Fitting Accuracy of Angular Contact Ball Bearings(2022年07月19日)

Angular contact ball bearings can be divided into Single row angular contact ball bearings, Precislon single row angular contact ball bearings, Double row angular contact ball bearings, Four-point contact ball bearings. In order to improve the running performance of angular contact ball bearings, it is necessary to improve the actual fitting accuracy of the bearing during installation. So, do you know how to improve the fitting accuracy? Today we will talk about some tips.

If rolling bearings want to achieve high matching accuracy, then in the process of installation, the relevant technology and equipment should be the most perfect. Moreover, it is necessary to accurately measure the dimensions of the inner hole and outer circle of the bearing, and then perform high-precision installation according to the measured data. It should be noted that the corresponding dimensions and shapes of the shaft and housing bore are to be matched to the angular contact ball bearing data measured under the same conditions.

During installation, the shaft and the seat hole are close to the two sides of the chamfer of the device, and two sets of marks on the deviation deviation should be made to make the deviation of the matching two sides unified. After the installation is completed in this way, the deviation on both sides will be partially offset. Installed in this way, the actual fit accuracy of the angular contact ball bearing will be improved.

FV produces many designs and sizes of anqular contact ball bearings. In addition to the bearings shown in the FV General Catalogue, we also can design and change drawing according to customer's actual requirement. Welcome to contact us!
