Our factory is specialized in producing all kinds of roller bearings and hand chain hoist roller, needle.

我厂专业生产各种轴承滚子及手拉葫芦滚柱、滚针。

In order to prolong the service life of roller bearing, a deep end-cavity roller is applied to roller bearing of cone bits.

国内现有牙轮钻头滚动轴承多采用短圆柱滚子轴承结构，滚子边缘处存在应力集中现象，使得轴承接触表面极易发生疲劳破坏，为提高牙轮钻头滚动轴承抗接触疲劳寿命，提出在牙轮钻头滚动轴承中采用凹端圆柱滚子的方案。

In China, the roller bearing cone bit is now equipped with short cylindrical roller, which has stress centralization on the edge, and it easily causes fatigue failure on the contact area.
