Notes:

1. Pounds at zero deflection based on pure radial load. Performance of pivot is a function of number of cycles, angular travel, and loading. Must use life cycle curves for selection of proper pivot. When the load is applied directly through a single spring, multiply capacity by 0.707.

2. At zero load, Torsional Spring Rate may change with radial load.

Notes:

1. Pounds at zero deflection based on pure radial load. Performance of pivot is a function of number of cycles, angular travel, and loading. Must use life cycle curves for selection of the proper pivot. When the load is applied directly through a single spring, multiply capacity by 0.707.

2. At zero load, Torsional Spring Rate may change with radial load.

外形尺寸单位为：英寸inch

载荷Load(Lc)和Capacity(Lt)单位为：磅pounds

TSR=Torsional Spring Rate=扭转刚度 单位=磅*英寸/度=lb*in/deg=6.474Nm/rad=0.113Nm/°


1，扭矩，旋转角度，扭矩刚度之间的关系


例如：

需要多大扭矩来使5016-600轴承旋转5度？

查上表得：5016-600 TSR=0.1134 pounds*inch/degree

TSR=TORQUE/ANGLE

TORQUE=TSR * ANGLE=0.1134*5=0.567 pounds*inch=0.064Nm.


2，关于枢轴中心轴漂移

由于枢轴的由内部两相互垂直的弹簧片构成，相当于两悬臂梁交叉垂直，当枢轴旋转时，中心轴会发生改变，如下图，当枢轴处于自由状态时即0度时，中心轴位于A，当枢轴旋转一定角度时，中心轴变成A'。


例如：5020-800轴承（外径为0.625英寸）旋转4度，它的中心轴漂移为：
查表（如需要此表请联系我们）得旋转4度时的因子为0.001，所以
0.6250x0.001=0.000625英寸=0.016mm
即轴承旋转4度，中心轴漂移了0.016mm 

测量图

如有需要计算轴承在带载荷下的轴向刚度，寿命计算，请联系我们，我们的技术工程师会很耐心的协作你~

另外，我们也接受轴承特殊材料定制，如非磁性材料，耐超高温低温材料，欢迎随时联系我们~
