hardalloy 1.牙掌轴承表面堆焊层，圆锥轴承，黄金焊接在一起银后降低，提高了承载能力和抗咬合能力;

2 ，轴承的O型密封圈耐磨损，耐高温的高饱和丁腈橡胶，增加密封环sectionreduces压力密封，精心设计的密封凸台outsidethe提高密封的可靠性。

3 ，使用钢丝球或卡锁苇锥的方式， CARDLOCK能承受高的芦苇钻压，钢珠锁定能adaptto高速。

4压差，防止钻孔fluidrestrictions在润滑系统中的所有橡胶储油囊，为bearingsystem提供了良好的润滑保证。

5 ， 250度的温度高温，新的油脂abrasionresistance 。

1. Tooth palm bearing surface surfacing layer of hardalloy, cone bearing with reduced after welding together gold for silver, improve the bearing capacity and resistance to bite ability;

2, bearing type O sealing ring is wear-resistant, hightemperature resistant high saturation NBR, increase the sealing ring sectionreduces the pressure seal, carefully designed sealing convex platform outsidethe improved seal reliability.

3, USES the steel ball or card lock reed cone way, cardlock can endure high reed drilling pressure, steel ball to lock the can adaptto high speed.

4 the differential pressure and prevent drilling fluidrestrictions in the lubricating system all rubber oil storage sac, for bearingsystem provides good lubrication guarantee.

5, 250 degree temperature the high temperature, abrasionresistance of new grease.
