最常見的球軸承類型是什麼？

The most common types of 球軸承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。深溝球軸承
深溝球軸承是最常用的球軸承類型之一，具有結構簡單、承載能力大、使用壽命長等優點。主要用於低轉速、高載荷領域，如電動工具。

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 球軸承
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.

六個薄壁軸承
薄壁軸承具有結構緊、重量輕、剛性高的特點，是各種輕型機械設備中不可缺少的零件。廣泛應用於卡盤、機械人、醫療設備等。

七、迷你軸承
迷你軸承是直徑小於9毫米的小型軸承，結構簡單，應用範圍廣泛，被廣泛應用於電動玩具、無線電子設備、手持工具等領域。

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.
