最常见的球轴承类型是什么？

The most common types of 球轴承s include deep groove ball bearings, angular contact ball bearings, and self-aligning ball bearings.

Ball bearings are divided into deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, thrust ball bearings, four-point contact ball bearings, thin-walled bearings and mini bearings and other seven types.
第一。深沟球轴承
深沟球轴承是最常用的球轴承类型之一，具有结构简单、承载能力大、使用寿命长等优点。深沟球轴承主要用于低转速、高负荷领域，如电动工具。

Second, angular contact ball bearings
Angular contact ball bearings bear radial and axial loads, can keep the load stable at the same time, has a long life and smooth operation and other characteristics. Mainly used in high-speed areas, such as spindles, motors and so on.

Self-aligning ball bearings
Self-aligning ball bearings can still work under the situation of mounting deviation and rotational deviation, and have the advantages of automatic centering and large load carrying capacity. Mainly used in heavy load, vibration and high speed field, such as vibrating screen, road roller and so on.

Fourth, thrust 球轴承
Thrust ball bearings can bear large axial load in one direction, compact structure and easy to install. Mainly used in large-scale heavy equipment, such as cranes, hydraulic presses and so on.

Five, four-point contact ball bearings
Four-point contact ball bearings bear radial and axial load, can keep the load stable, and in the bearing has high flexibility and adaptability. Mainly used in joints, rotary table and other rotating equipment.

六个薄壁轴承
薄壁轴承结构紧凑、重量轻、刚度高，是各种轻型机械设备中不可或缺的部件。广泛应用于卡盘、机器人、医疗设备等。

七、微型轴承
微型轴承是直径小于 9 毫米的小型轴承，结构简单，应用广泛，被广泛应用于电动玩具、无线电子设备、手持工具等领域。

Ball bearings are divided into seven types: deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, thrust ball bearings, four-point contact ball bearings, thin-walled bearings and mini bearings. Different types of bearings have different structures and areas of application to meet various usage requirements.
