Shot blasting machine crawler (rubber wear-resistant crawler), composed of three layers, the outermost covered rubber, can reach more than 20 MPa, can directly contact with the workpiece to be cleaned, the elasticity and wear resistance of the rubber are very high . The material is natural rubber. The rubber track of the shot blasting machine has the characteristics of high strength, impact resistance, large interlayer adhesion, high elasticity and long service life. The outer surface of the crawler is optional: flat, with one-shaped rib or with eight-shaped ribs, and the inner ring of the crawler is optional: with or without guiding ribs.
