How do I choose the right thin-walled angular contact ball bearing type?

What is thin section angular contact ball bearing?

Thin section angular contact ball bearings are lightweight, with high hardness, small cross-sectional area, and multi load capacity. In order to obtain low friction torque, high rigidity, and good rotational accuracy of the bearings, small outer diameter steel balls are used. The use of hollow shafts ensures lightweight and wiring space.

Features of thin section angular contact ball bearing

Thin section angular contact ball bearing achieve extremely thin bearing thin-sections, as well as miniaturization and lightweight of products. The diversity of products expands their scope of use.

1. The use of bearings can reduce vibration, reduce noise, prevent pollution, and improve labor conditions in machinery;

2. During operation, a transfer film can be formed to protect the grinding shaft without any biting phenomenon;

3. The hardness requirements for grinding shafts are low, and shafts that have not been modulated can be used, thereby reducing the machining difficulty of thin-walled bearing related parts;

4. The thin-walled bearing structure is lightweight and can reduce mechanical volume. No oil lubrication or low oil lubrication, suitable for places where refueling is impossible or difficult, and can be used without or with minimal maintenance;

5. Good wear resistance, low friction coefficient, and long service life;

6. Thin walled bearings have similar static friction coefficients and can eliminate crawling at low speeds, thereby ensuring the working accuracy of the machinery.

How do I choose the right thin-walled angular contact ball bearing type?

There are a number of factors to consider when choosing the right thin-walled angular contact ball bearing model, and here's how:

Load conditions

Radial load: selected according to the actual radial force of the bearing. In general, thin-walled angular contact ball bearings are suitable for medium radial loads, but if the radial loads are large, consider increasing the width of the bearing or choosing a larger version.

Axial load: Angular contact ball bearings are mainly subjected to axial loads, and the axial load capacity of the bearings needs to be determined according to the axial force that the equipment needs to bear. In general, the axial load capacity of a bearing is related to its contact angle, and the larger the contact angle, the higher the axial load capacity.

RPM requirements

High-speed equipment requires thin-walled angular contact ball bearings with good high-speed performance. In general, the ultimate speed of the bearing is given in the product brochure, and the selection should ensure that the ultimate speed of the selected bearing is higher than the actual operating speed of the equipment. At the same time, the lubrication and heat dissipation of the bearings need to be considered to ensure reliability at high speeds.

Accuracy class

The accuracy class of the bearing is selected according to the accuracy requirements of the equipment. Common accuracy levels are P0, P6, P5, P4, etc., and the accuracy increases sequentially. P0 level accuracy can be selected for general ordinary machinery; For machine tool spindles, precision instruments, etc., which require high accuracy, P5 or higher precision bearings are required.

Installation dimensions

It is necessary to select the appropriate bearing type according to the space size of the installation site. First, determine the inner diameter of the bearing, which should match the diameter of the shaft; Then, according to the width of the installation space and the outer diameter limit, the appropriate bearing width and outer diameter size are selected. In addition, it is also necessary to consider the structural form of the bearing, such as whether there are flanges, seals, etc., to ensure that it can be correctly installed in the equipment.

Operating temperature

If the equipment is working in a high-temperature environment, it is necessary to choose a high-temperature resistant bearing material and grease. Generally speaking, ordinary bearing steel will have problems such as hardness reduction and dimensional changes at high temperatures, which will affect the performance and life of the bearing. In this case, special high-temperature bearings, steel or ceramic bearings can be used. At the same time, it is also necessary to select the appropriate grease according to the operating temperature to ensure good lubrication of the bearing at high temperatures.

Reliability and longevity requirements

For some critical equipment or long-running equipment, it is necessary to choose bearings with high reliability and long life. You can refer to the life calculation method provided by the bearing manufacturer to calculate the life expectancy of the bearing according to the working conditions of the equipment (such as load, speed, operating temperature, etc.), and ensure that it meets the requirements of the equipment. In addition, you can also consider choosing a well-known brand of bearings to improve the reliability of the product.

Special requirements

Some special working environments or equipment requirements may require bearings with special properties, such as corrosion resistance, insulation, low noise, etc. For example, in the chemical industry or in humid environments, bearings made of corrosion-resistant materials such as stainless steel or ceramics can be used; For equipment with electrical insulation requirements, bearings with an insulating coating or made of insulating materials are available.
