23080CAKF3/C3W33

23080CAKF3/C3W3 is a large-sized heavy-duty type cylindrical-hole self-aligning roller bearing. It integrates a copper alloy CA cage, a 1:12 conical hole, an outer ring with three oil injection holes for W33 ring-shaped lubrication grooves, and a C3 large clearance structure. The core positioning is to provide stable core support for key shaft systems of heavy-duty low-speed heavy-load equipment in fields such as metallurgy, mining, construction materials, ports, and power, including rolling mill rolls, main shafts of crushers, cement mills, heavy-duty reducers, and crane rotation mechanisms. This support enables convenient adjustment of clearance and installation, high load-bearing capacity and resistance to impact, automatic compensation for shaft misalignment, adaptation to high-temperature expansion and strong vibration conditions, and support for long-term online grease replenishment. It meets the strict requirements of continuous high-load operation under harsh conditions, ensuring low failure rate and long-term stable operation of key parts of large-scale heavy machinery equipment.
