Mold guide sleeve, also known as (mold guide sleeve, high-force brass bearing) is on the matrix of high-force brass. A high-performance solid lubricant product inlaid with graphite or MoS2 solid lubricant. It breaks through the limitation of general bearings relying on oil film lubrication. In the process of use, the solid lubrication and the shaft are rubbed by frictional heat, forming excellent conditions for coexistence and lubrication of oil and powder, which not only protects the shaft from wear, but also makes the solid lubrication characteristics eternal. Its hardness is twice as high as that of general copper sleeves, and its wear resistance is also twice as high.
