There are four kinds of stabilizers, namely, replaceable sleeve stabilizer, integral spiral stabilizer, integral prism stabilizer, and three-roller stabilizer. Each kind has two types: string type and near-bit type. The body is made of high-strength alloy steel, and the wear-resistant layer adopts bead-welded hard alloy with good stability and high abrasion resistance.
