Series NF-300
The rollers of these bearings are essentially cylindrical in shape providing modified line contact with the cylindrical inner and outer rings raceways. The rollers are accurately guided by ground ribs on either the inner ring or the outer ring, thus making these bearings suitable for heavy radial loads and high speed operation. For best results, these bearings should be accurately aligned. The cylindrical shape of the rollers allows the inner ring to have considerable axial movement relative to the outer ring except for the bearings with the prefix “NH”. This feature is valuable in accommodating thermal expansion in applications where both the inner and outer ring must be press-fitted. Since the inner and outer rings can be separated from each other, the assembly of equipment is frequently facilitated.
这些轴承的滚子基本上是圆柱形的，提供与圆柱形内圈和外圈滚道的改进线接触。滚子由内圈或外圈上的磨肋精确引导，从而使这些轴承适用于重径向载荷和高速运行。为获得最佳效果，这些轴承应精确对齐。滚子的圆柱形状允许内圈相对于外圈有相当大的轴向运动，但前缀为“NH”的轴承除外。在内环和外环都必须压装的应用中，这种特性对于适应热膨胀非常有价值。由于内环和外环可以彼此分开，因此常常便于设备的组装。
