230/560CA/W33

As the leading model of double-row self-aligning roller bearings, 230/560CA/W33 holds a core position due to its unique design of an integral brass cage combined with an outer ring annular oil groove and three lubrication holes. This design provides a three-in-one key support solution of heavy-load bearing, self-aligning, and long-term lubrication for ultra-large low-speed heavy-duty equipment in industries such as metallurgy, mining, and cement. It is suitable for harsh working conditions where the shaft system is prone to deflection, installation is not concentric, and continuous operation is required for a long time. It is a "stabilizing pillar" component that ensures high reliability and low maintenance costs in core equipment such as large rolling mill support rolls, ball mills, vertical mills, and crane slewing mechanisms. With an inner diameter of 560mm, an outer diameter of 820mm, and a width of 195mm, and performance parameters of approximately 5780kN dynamic load, 10200kN static load, and grease lubrication ≤ 320r/min, oil lubrication ≤ 430r/min, it precisely meets the comprehensive requirements of ultra-large equipment for extreme load-bearing capacity, error compensation, and continuous operation capability, making it an irreplaceable high-rigidity selection in such scenarios.
