23084

23084 is a large-sized double-row self-aligning roller bearing (common suffixes such as CA/W33, CAK/W33, etc.). Its core function is to provide high rigidity and long service life radial main load-bearing and bidirectional auxiliary axial load-bearing for key shaft systems of heavy-duty low-speed and heavy-load equipment in industries such as metallurgy, mining, construction materials, and ports. The symmetrical rollers + stamped steel cage design enhances the heavy-load impact resistance, and the automatic self-aligning (≤2°) adapts to shaft system angle misalignment and unbalanced load conditions. The cylindrical hole / conical hole (K) is suitable for tight-fit installation. The outer ring W33 lubrication groove + oil injection hole supports online long-term grease replenishment, suitable for stable support and easy maintenance of equipment such as rolling mill rolls, crusher main shafts, cement mills, and heavy-duty reducers under heavy load, temperature fluctuations, and intense vibration conditions, ensuring the low-fault continuous operation of large-scale heavy machinery equipment.
