Copper-based Oil-Impregnated Powder Metallurgy Bearing LM-FU1 Copper-based Oil-Impregnated Bearing is manufactured using tin bronze powder as raw material, formed through mold pressing, sintered at high temperatures, and then shaped. Its matrix features fine, uniformly distributed pores, which are vacuum-impregnated with lubricating oil to achieve an oil-retaining state. This product features short-term lubrication without refilling, low operating costs, and adjustable inner/outer diameter dimensions. It is suitable for medium-speed, low-load applications. Widely adopted in household motors, power tools, textile machinery, chemical processing equipment, automotive industries, and office equipment.
