230/670CAF3

230/670CAF3 is a super-large double-row self-aligning roller bearing. Its core function is to provide a long-lasting and stable support solution with high load capacity, bidirectional axial positioning, automatic self-aligning, and adaptability to installation errors and shaft deflection conditions for ultra-large low-speed heavy-duty equipment in industries such as metallurgy, mining, cement, and wind power. It is particularly suitable for scenarios with long-term non-stop operation, frequent disassembly and maintenance, and thermal expansion requirements. The CA type inner ring with double-sided flanges and a machined cage design ensures bidirectional axial positioning and stable roller guidance. The F3 type outer ring with a ring-shaped oil groove and 3 lubrication holes supports continuous on-site oil replenishment. The double-row self-aligning roller structure is compatible with non-coincident shafts or shaft deflection conditions, combined with the convenient installation feature of the conical hole (suitable for locking sleeves / disassembly sleeves), to achieve a balance of high reliability, long service life, and maintenance convenience in heavy-duty conditions, and to meet the core support requirements of large key equipment such as rolling mill supporting rolls, ball mills, vertical mills, rotary kilns, and wind turbine main shafts.
