Product Description

 structure features:

1, the floating bearing structure, floating element high strength, high by flexibility, high resistant, high wear resistance characteristics of new material, the surface is made from solid lubricant processing. In the low bearing vice relative linear velocity at the same time, reduce the friction surface temperature, can effectively enhance drilling pressure or high high speed drilling process conditions of bearing life and bearing reliability.

2, with high precision metal seal. Metal seal by a deputy elaborate design processing of metal sealing ring as bearing axial dynamic seals, two high elastic rubber for can ring located in tooth palm and die as static sealing seal area, the optimization of the seal compression value to ensure that the two metal ring seal surface always kept in good contact.

3, steel ball lock, suitable for the high speed disc.

4, the differential pressure and prevent drilling fluid restrictions in the lubricating system all rubber oil storage sac, for bearing system provides a good lubrication guarantee.

5, **0 ° C using resistant to high temperature, abrasion resistance of new grease.

6, with teeth bit high strength and high toughness cemented carbide gear, optimization of the tooth row number, gear, toothy height and unique alloy tooth shape, give full play to the drill with high wear resistance and excellent gear cutting ability. Steel teeth drill tooth face apply welding new wearing material, in keep steel teeth bit high mechanical penetration rate at the same time, improve the cutting teeth drill life.

7, according to the teeth type disc bit can be divided into milling gear (steel teeth), with disc bit teeth (with hard alloy with disc on disc bit teeth); According to the number of disc can be divided into the single, double disc disc, three die and disc bit more. At present, the most, the most common use of the rock bit is three.
