軸承的精度等級影響其運行的平穩性和精確性。常見的精度等級包括ABEC（美國軸承製造協會）和ISO（國際標準組織）等級。
當談到軸承時，我們經常會聽到「ABEC等級」這個詞彙，這是用來衡量軸承精度的指標。ABEC（Annular Bearing Engineering Committee）等級是由美國軸承製造商協會制定的，旨在標準化軸承的生產和評價，使消費者能更容易理解和比較不同等級的軸承。然而，ABEC等級並不完全適用於所有應用情況，特別是對於電動自行車而言。
ABEC等級表格
| ABEC | ISO 492 | DIN 620 | JIS |
| ABEC 1 | Class Normal | P0 | Class 0 |
| ABEC 3 | Class 6 | P6 | Class 6 |
| ABEC 5 | Class 5 | P5 | Class 5 |
| ABEC 7 | Class 4 | P4 | Class 4 |
| ABEC 9 | Class 2 | P2 | Class 2 |
※國際標準化組織(ISO)的標準是 ISO 492，德國標準是 DIN 620，日本標準是 JIS B1514
⚠️ABEC等級的評估範圍從ABEC-1到ABEC-9，命名與公差成反比，即數字越大意味著公差越低。較高的ABEC等級（較低的公差）提供了更好的精度，這可能會影響到設備運轉的順暢度和效率，但不一定使安裝軸承的零部件旋轉得更快。
以下表格列出了根據 ABMA 標準 20 的實際 ABEC 公差，分別列出內圈和外圈的公差，並涵蓋了公制單位。這些表格在確定如軸和軸承座等部件的尺寸和公差時非常有用。設計師在確定對手件尺寸時，應始終在最大和最小材料狀態下進行公差疊加研究，尤其是在設計微型滾珠軸承時。

(1) P0, ABEC-1 精度等級 (ISO Class Normal)
(2) P6, ABEC-3 精度等級 (ISO Class 6)
(3) P5, ABEC-5 精度等級 (ISO Class 5)
ISK軸承一般為普通級，最常用的普通級軸承(0級)的公差精度見附表所示。當客戶對精度有特殊要求時，訂貨時應規定之。
