The Bearing Plate (OEM Part No. 3128280890) is a wear part compatible with Ma Cheng E70, Simba E7C, and Boomer XE3C drilling rigs. Manufactured from hardened alloy steel, it is designed for use in load distribution or support systems at bearing mating surface positions. The bearing plate ensures even load transfer, reduces wear on mating components, and maintains structural alignment during drilling operations. Its durable, wear-resistant construction provides long-lasting performance under demanding underground mining and tunneling conditions, enhancing mechanical stability, operational efficiency, and reliable support across heavy-duty drill assemblies.
