双列球面向心滚柱轴承的负荷能力较其他类型的轴承为大,并且有自动调心的性能,可在内圈与外圈中心线间有3°倾斜角的条件下工作,故能使用于轴承内外圈轴心线不能平行的轴上,简化了轴承箱的加工和装配工艺,所以广泛用于矿山机械、轧钢机械和超重运输机械等重型机械中。 Double row spherical radial roller bearing load capacity larger than other types of bearings, and self-aligning performance, the center line in the inner ring and outer ring with a 3 ° angle under the conditions of work, it can be used In the bearing inner and outer ring shaft axis can not be parallel to the shaft, simplifying the bearing box processing and assembly process, it is widely used in mining machinery, rolling machinery and heavy transport machinery and other heavy machinery.
