SILVERTHIN A型角接触薄截面轴承参数表图文资料

A型角接触英制等截面薄壁轴承参数按 SAA、SA、SB、SC、SD、SF、SG 系列列出内径、外径、轴肩直径、径向与轴向额定载荷及重量。A型适用于以轴向载荷或力矩载荷为主的工况，在多数应用中通常至少两个轴承组合使用。

2. 英制开式角接触 A 型轴承参数表

A 型角接触球轴承适用于以轴向载荷或力矩载荷为主的工况，也可适应径向、轴向、力矩及复合载荷。在大多数应用中，A 型轴承通常需至少以两个轴承组合使用。

径向载荷	轴向载荷	力矩载荷	往复载荷	复合载荷
好	卓越	卓越 (配对时)	卓越 (配对时)	好

通用备注：额定载荷值不可相加计算；沟道宽度公差通常为 +0.000/-0.005 英寸；允许匹配的最大轴或轴承座圆角半径随系列不同而变化。
