Shaft
    Because the balls in IN'S Super Linear Ball Bearing as rolling elements are running directly on the shaft surface, the hardness, surface finishing, and tolerance of shaft will largely affect the travelling performance of Super Linear Ball Bearing.

The shaft must have following conditions:
1)Hardness
    The hardness must be HRC 58 to 64.
    The shaft hardness below HRC 58 will lead decreasing of travel life and permissible load.

2) Surface Finishing
   The Surface finishing must be 1.6S or better for the smooth operation.

3) Tolerance
   The correct tolerance of the shaft diameter is recommended as shown on Table 9 and Table 10.

Fitting
   Recommended fittings between Super Linear Ball Bearing and shaft are shown in Table 9 and Table 10.
   Please note when the housing bore tolerance is H7, there are tight fit at the both ends of outer sleeve of metric trpe.
