The Plain Bearing (OEM Part No. 3128256166) is a bearing replacement compatible with Epiroc and BMH drilling rigs, including S7D and S7D-1 models. Made from durable bronze or alloy steel, it is designed for use within the drill feed or support system at rotating shaft support positions. The bearing reduces friction, ensures smooth rotational motion, and supports load transfer between moving components. Its high-strength, wear-resistant construction provides long-lasting performance under heavy-duty underground drilling conditions, maintaining mechanical alignment, operational stability, and the overall efficiency of the drill assembly during continuous mining and tunneling operations.
