230/670CA/W33

230/670CA/W33 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, online grease replenishment capability, 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 W33 outer ring with oil grooves and oil holes supports continuous online grease replenishment. The double-row self-aligning roller structure is compatible with misalignment between the shaft and the housing or shaft deflection conditions. Combined with the convenient installation feature of the conical hole (suitable for tightening sleeves / disassembly sleeves), it achieves a balance of high reliability, long service life, and maintenance convenience in heavy-duty conditions, and is suitable for 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.
