1. High-quality base self-lubricating bearings material, copper-based brass guide bronze wear plate guide bush is used through continuous casting and extrusion rolling of high force brass material, dense organization, Sn, Ni, Pb, S, and other impurities are very few, not even more than 0.1%, hardness more than HB200, to ensure excellent wear resistance.

2. High-quality natural graphite self-lubricating bushings material, the use of high-quality natural graphite, the use of advanced powder extrusion sintering technology, so that the graphite column of uniform organization, dense standard, in addition to self-lubrication, their own loss is extremely small, fully ensure that the lubricant content between the organization is sufficient to reduce the wear of the guide plate guide bush substrate, effectively extend the service life.

3. Vacuum immersion technology, the use of vacuum immersion technology, fully ensures that any gap between the graphite column tissue is immersed in saturated lubricant, so that, after the relative friction of the substrate heat, oil molecules volume expansion, from the graphite column tissue seepage to the surface of the substrate, instantly reduce the substrate temperature at the same time, and to achieve the ideal self-lubricating effect.

4. Graphite hole diameter, in the premise of ensuring the stiffness and strength of the substrate enough, the diameter of the graphite hole is drilled relatively small so that the arrangement of graphite column on the substrate appears relatively dense, the lubricant content after the vacuum immersion oil is relatively more saturated, the lubrication effect is better.
