The MG-820 Steel with Lead Bronze Powder Marginal Bearing is a high-performance, maintenance-free or low-maintenance solid-lubricant bearing. It utilizes a unique three-layer composite structure that seamlessly combines the load-bearing capacity of a high-strength steel backing, the wear resistance of a lead bronze alloy, and the self-lubricating properties of a solid lubricant. Designed for operation under extremely harsh operating conditions, it addresses the lubrication challenges faced by traditional bearings in heavy loads, low speeds, high temperatures, and environments where oil film formation is unavailable.
Core Definition Analysis:
MG-820 Steel: A high-strength, low-carbon steel backing provides structural support and load-bearing capacity.
Lead Bronze Powder: A copper-based alloy layer sintered onto the steel backing via powder metallurgy, serving as the primary friction contact surface and wear-resistant layer.
Marginal Bearing: refers to the process of regularly drilling holes in the alloy layer through machining and inlaying (Marginal) solid lubricants (such as graphite/molybdenum disulfide mixture).
