Sob-2s oil-free lubricating bearing is an improved product of sob-2. It is a polymer material with copper back as the matrix, spherical tin bronze powder in the middle, acetal resin as the surface rolling, lipophilic fibers and special lubricants. DS bearing is the same product abroad, which is suitable for dry friction and less oil lubrication under normal temperature. It has the advantages of low friction coefficient, good wear resistance and oil-free lubrication.
At present, the product has been used in swing movement, wear and corrosion, such as winder, bulldozer, printing and dyeing machine, shearer and crane, overhead crane and other occasions.
