摘　　要：典型或标准的交叉圆柱滚子滚动导轨支承,其所用滚子的长径比为1或是非常接近于1。另一种结构是长径比远小于1的交叉圆柱滚子滚动导轨支承,这种结构克服了前者的一些缺陷,改善了动态性能,能够提供更高的承载能力和工作可靠性,以及更好的装配和维护性能。In typical or standard rolling guideway bearing products with crossed rollers, the rollers is made in 1.0 ratio of length to diameter of the roller, or very closed to 1.0.In another type of products, L/D ratio is much smaller than 1.0. The latter can resolve some problems ever in the former,improve dynamic performance, provide for higher bearing capacity and work reliability as well as better performance of assembly and maintaince.
