OEM ZPMC sheaves are typically Hot Rolled Steel with a hardness of HB 220-260. Over time, &#8220;Corrugation&#8221; (wavy wear patterns) develops in the groove, which rapidly destroys expensive wire ropes.\n            <\/p>\n            <p class=\"zk-p\">\n                <strong>Zhenke Maintenance Protocol:<\/strong> We supply direct replacements from ZPMC&#8217;s casting supplier in Nantong. For high-cycle cranes, we also offer <strong>Nylon (MC Polyamide)<\/strong> sheaves which reduce wire rope wear by up to 40% and lower the boom weight.\n            <\/p>\n            \n            <div class=\"zk-highlight-box\">\n                <strong style=\"color: #003366; display: block; margin-bottom: 10px; font-size: 1.1rem;\">Trolley Wheel Warning:<\/strong>\n                <p style=\"margin: 0; font-size: 0.95rem;\">\n                    ZPMC trolley wheels use a specific interference fit for the bearings.
