注：1.链号是⽤英制单位表⽰的节距，它是⽤lin/16为1个单位，⽽⽶制节距p=链号数X25.4mm/16。

2.链号中A、B表⽰两个系列：A系列源于美国，流⾏于全世界；B系列源于英国，主要流⾏于欧洲。

两系
3.对繁重的⼯况不推荐使⽤过渡链节
4.表中b7的四级尺⼨取决于⽌锁件的型式，但不得超过表中说给尺⼨，详细资料应从链条制
5.链条最⼩抗拉载荷应超过标准中规定的试验⽅法所施加到试样上发⽣破坏的抗拉载荷的数字。

最⼩抗
6.081、083、084、085链条仅有单排式，固标记中的排数可省略。

7.标记⽅法：链号-排数-整链链节数标准号。

抗拉载荷的数字。

最⼩抗拉在和并不是链条的⼯作载荷，知识不同结构链条之间的⽐较数据。

关于链条应⽤⽅⾯的于链条应⽤⽅⾯的资料（包括单位长度质量），应向制造⼚咨询或查阅公布的数据。
