The ABEC scale is an industry accepted standard for the tolerances of a ball bearing. The ABEC scale is designed to provide bearing manufacturers dimensional specifications that meet the standards of precision bearings in a specified class.

Applications should only require ABEC 1 or ABEC 3 ball bearings. When highly precise position is required, ABEC 5 or ABEC 7 ball bearings should be specified. The ABEC scale is an industry accepted standard for the tolerances of a ball bearing.

ABEC 仅仅是一种给轴承公差等级定义的方法。 国际标准化组织 （International Organization for Standardization）和德国标准组织（DIN）也有类似同的标准来衡量轴承的精度。在ISO 和 DIN 系统中， 编号越小意味着公差带越窄，编号越大意味着公差带越宽。

Choosing the right ABEC rating for your bearing application requires a sound understanding of what the ABEC scale represents. Most bearings sold belong to ABEC ratings 1 and 3, and perform very well. These bearings are on the middle end of the spectrum and are commonly found in non-precision applications such as automotive components ...

The ABEC tolerances listed in the attached document are current as of this posting. These tolerances are reviewed regularly and updated as required. The ABMA Standards may be obtained by contacting: ABMA, 2025 M Street, NW, Suite 800, Washington, DC 20036.

2025年1月9日 · ABEC, which stands for Annular Bearing Engineers Committee, has established a series of precision grades to define the tolerances and quality levels of bearings. These grades help engineers and manufacturers select the most appropriate bearings for their specific applications. ABEC 1 This is the least precise grade among those commonly mentioned.

abec标尺是滚珠轴承公差的行业公认标准。 它是由美国轴承制造商协会（ABMA）的环形轴承工程委员会（ABEC）开发的。 从最大公差到最小公差有五类：1、3、5、7和9。

2008年5月26日 · 轴承abec－1质量指的是什么？ ABEC-1 是轴承行业中的一种质量表示方法，ABEC-1为最普通的轴承，也就是质量符合国家规定的标准 ABEC-1。 其标准还有：ABEC-3ABEC-5ABEC-7ABEC-9后边的数字越大代表的质量越高，普通的一
