618/1240X1C3

618/1240X1C3 is a wide-clearance customized model of large-sized thin-walled deep groove ball bearings. Its core positioning is to adapt to high-precision rotational support components of large industrial equipment in scenarios such as high-temperature expansion, heavy-load deformation, or installation deviations. Relying on the structural optimization corresponding to the X1 marking and the C3 wide-clearance design, while maintaining the basic dimensions of 1240mm inner diameter, 1500mm outer diameter, and 118mm width, it specifically enhances the adaptability to working conditions and operational stability. It provides reliable support and protection for large machinery with temperature fluctuations, load impacts, or installation space limitations. It inherits the basic advantages of deep groove ball bearings, such as bidirectional bearing capacity, low friction, and easy installation. The X1 suffix usually corresponds to internal structure improvements (such as reinforced inner rings and optimized rolling elements), and the C3 wide-clearance can effectively compensate for the component expansion in high-temperature environments, absorb installation deviations and vibration impacts during operation, avoiding problems such as jamming and increased wear due to insufficient clearance. At the same time, it also ensures the bearing strength and rotational accuracy under heavy-load conditions. Its applicable scenarios focus on heavy-load fields that need to cope with temperature changes or installation errors. It covers metallurgical industry high-temperature rolling mills, continuous casting line equipment (suitable for high-temperature expansion requirements), chemical industry large reactors, high-pressure compressors (able to withstand load fluctuations and medium corrosion), and also meets the requirements of mining machinery heavy-duty crushers, construction machinery heavy cranes (absorbing installation deviations and vibrations), power industry large power generation units (ensuring stable support at high rotational speeds). Through the dual support of wide clearance and structural optimization, it guarantees the long-term continuous operation of equipment under complex conditions, reducing maintenance costs and downtime losses.
