Bearing bushes in magnetic pumps and canned motor pumps are specialized components designed to provide lubrication, cooling, and wear resistance under demanding operating conditions. Bearing bushes act as sleeves that support the pump shaft, ensuring smooth rotation without direct metal-to-metal contact. They reduce friction and protect the shaft from wear, extending pump life. In magnetic and canned motor pumps, the pump liquid itself circulate between rotating and static parts due to Straight or helical grooves are often incorporated to enhance circulation of the lubricating medium. They are typically made from advanced materials like silicon carbide, carbon, or tungsten carbide to withstand high pressure, speed, and corrosive environments.
