It is made of high quality low-carbon steel, and with lead-tin-bronze alloy(cu pb10 sn10),the alloy surface is integrated with lozenge oil grooves. The special solid lubricants inlaid in the grooves. It has good lubricating property and corrosion resistance and can work under such conditions as oilless or no oil. It is particularly suitable to high temperature, water soaking or other occasions where oil cannot be added. |
