Adopting spring load device for continuing to load, find the ultimate load that the piston ring be endured.
为了能对活塞环进行连续加载，采用弹簧加载装置，从中找出活塞环所能承受的极限载荷。

The limits are valid for bearings before mounting under zero measuring load, and with no axial displacement of one ring relative to the other.
在测量负荷为零、而且一个套圈相对于另一套圈无轴向位移的情况下，这些限值对安装前的轴承有效。

Two-way pressure has mounted on ball bearings between the shaft and two outer rings, in the middle ring and outer ring were added between the steel ball, able to withstand the two-way axial load.
