轴承 规格表
6种规格数据
轴承支撑旋转或直线运动的轴并减少摩擦。深沟球轴承最通用，同时承受径向和轴向载荷。重径向载荷选滚子轴承；高速复合载荷选角接触轴承。密封类型(ZZ/2RS)也显著影响轴承寿命。

常见问题 (FAQ)
What does bearing number 6001ZZ mean?
60 = deep groove ball bearing, 01 = 12mm bore (01×5+7), ZZ = double metal shields. 2RS indicates rubber seals on both sides.
What is the bearing L10 life rating?
L10 is the fatigue life at which 90% of a bearing population survives without failure — the rated life at 90% reliability.
What is bearing preload?
Preload applies an axial force to eliminate internal clearance, improving stiffness and running accuracy. Used in machine tool spindles and precision robots.
