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。

采用高强度和高toughnesscarbide齿轮6，设置步操，优化了牙行号，齿轮，露齿heightand独特的合金齿外形的设计上，充分发挥了集英尺高wearresistance和优异的切削能力的位。 尺位齿面applywelding新耐磨材料，并保持机械钻头bitruler速度的同时，提高钻头的切削齿的生活。

产品优势：

HA系列位办理O形橡胶密封滑动bearingdrill位，在常规使用能承受的压力高速钻孔，withdifferent切削结构，能适应极软，硬地层。

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.

6, set foot drill using high strength and high toughnesscarbide gear, optimize the design of the tooth row number, gear, toothy heightand unique alloy tooth shape, give full play to the set feet high wearresistance and excellent bit of cutting ability. Ruler bit tooth face applywelding new wear-resistant materials, and to maintain the mechanical drill bitruler speed at the same time, improve the drill bit cutting teeth life.

Product advantage:

HA series bit for O form rubber sealing sliding bearingdrill bit, in a routine use can withstand high speed drilling of pressure, withdifferent cutting structure, can adapt to a very soft and hard strata.
