SG Iron Sleeves are mostly introduced for the protection against wear and tear between mechanical moving components. These sleeves are designed with high-quality spheroidal graphite iron. The main purpose of casting these sleeves using spheroidal graphite iron material is to offer high impact resistance and very good thermal conductivity properties. Also, the sleeves have a better ductility nature so they give high wear and tear resistance. Our provided sleeves are extensively used in various types of displacement engines. Available in different standard sizes and shapes, these SG Iron Sleeves can be used for a long time without any modification.
