Rotary drilling single roller cone drill bit for foundation bore pile machine

Samples to customize, we have capacity to design the new products. We can design nonstandard products according to customer's drawing and sample.

(1)The floating bearing structure, floating element is made of new materials with high strength, high elasticity, high temperatureresistance, high wear resistance characteristics is made, the surface of solid lubricant processing. At the same time reduce the friction surface temperature, can effectively improve the high speed drilling technology under the condition of bearing service life and reliability.

(2)High strength and high toughness cemented carbide teeth, high precision lathe technology and cold pressing technology have been used to improve the impact resistance of the teeth.

(3)Optimization design of the tooth row number, number of teeth, teeth height and unique alloy tooth shape, give full play to the cutting ability and cutting speed.

(4)Inner hole welding antifriction alloy bearing, improve anti bite ability.

(5)The high temperature of **0 degrees centigrade, the new grease and low wear, improve the ability of high temperature resistant sealing drill lubrication system.
