230/560

230/560 is a double-row self-aligning roller bearing (common suffixes include CA/W33, CAE4, K, etc.). The core positioning is for metallurgy, mining, cement, heavy machinery industries, etc., for low-speed heavy-load equipment with easily deformed shaft systems and installation misalignment (such as rolling mill support rollers, ball mills, vertical mills, crane rotation mechanisms, large gearboxes, crushers, etc.). It provides a heavy-duty support solution that combines ultra-large radial load-bearing and bidirectional axial load-bearing, 1°–2.5° self-aligning compensation for coaxiality deviation, outer ring W33 lubrication grooves and oil holes to support long-term online grease replenishment (for some models), and compatible locking rings/retention rings (K type) for quick assembly and precise gap adjustment. Its inner diameter is 560mm, outer diameter is 820mm, and width is 195mm. The basic rated dynamic load is approximately 5000–5780kN, and the static load is approximately 10200–10700kN. Grease lubrication speed is ≤320r/min, and oil lubrication speed is ≤400–430r/min. It can stably withstand extreme working conditions and is suitable for the long-term operation and convenient maintenance requirements of heavy equipment.
