SF-60 铜+钢球 Brass material+steel ball |
SF-61 树脂+钢球 POM material+steel ball |
SF-62 铝+钢球 Aluminium material+steel ball |
优点与用途 Advantage and application scope 传统的具有相对运动的孔与轴是有一定间隙的，并孔与轴之间的运动摩擦系数较大，使用钢球保持圈后，使轴与孔不直接接触，而是中间通过有微量过盈的钢球，因而运动精度高，滚动摩擦代替了滑动摩擦，滚动灵活，摩擦系数小，使用寿命长、在既有转动、又有移动的场合，用无油或加油的轴套与轴相配，虽然能满足，但运动精度较低，用滚动轴承，只能满足轴相对转动的场合，而钢球保持圈，则上述二个条件均满足，目前已广泛应用于冷冲模架、高精度机床、机床附件以及要求高精度轴向或轴径向同时运动场合。 As the traditional work-craft has some grudge between bushing with posts, and the coefficient of friction is larger, now we have changed the work-ways to steel-ball directly face to face guide bushing, so the precision is machine, die machine, high precision machine which need rotation and vertical motion. | ||
