⑴ 横条的间距有A、B两种,A表示中心距为100mm,B表示中心距为50mm. ⑴ A,B are the two types of cross bar pitch A=100mm(center to certer)B=50mm(center to certer)
⑵ 纵条的间距有三种: 1表示系列1,间距为30mm(中心距) 2表示系列2,间距为40mm(中心距) 3表示系列3,间距为60mm(中心距)
⑵ There are three types of bearing-bar pitch
Bearing bar pitch: Series1(1)= 30mm(center to certer) Series2(2)= 40mm(center to certer) Series3(3)= 60mm(center to certer)
⑶ 纵条的侧边状态有P、S两种:
P表示平面形(在标记中可省略);S表示齿形。 There are two types (P.S) for the sides Shape of the bearing bar P=Plain S=Serrated
