We offer a wide variety of near bit stabilizers and string stabilizers according to API Spec.7 from China.

            Integral Spiral Blade Stabilizers is divided into string type and near-bit type according to the position differently, there are many ways to increasing abrasive resistance, e.g. tungsten carbide, it owns high hardness and great toughness, high resistance, long service life, and so on.
