Rolling Mill Bushing: Bronze Metallurgy, Heavy-Load Bearing Design, Lubrication, and Reliable Mill Availability
A rolling mill bushing is a heavy-duty plain-bearing component that supports or guides roll necks, screw-down systems, chocks, coiler mandrels, pivots, and related mill mechanisms. It operates under high radial load, shock, vibration, heat, cooling water, scale, grease or oil, and frequent maintenance pressure. Bronze, aluminum bronze, manganese bronze, leaded bearing bronze, steel-backed bimetal, graphite-plugged bronze and composite materials can be appropriate, but material selection must match roll force, speed, temperature, lubrication, shaft condition, fit, and inspection requirements.
