FIT

The fit of Stroke Rotary Bushing with shaft and housing is recommend as shown in Table 1.

Since this series may function in both rotary and linear directions at the same time, radial clearance should be held to minimum if shock load is applied or vibration is present during the operation. When this series is used in a vertical axis or very accurate movement is required, it is especially recommended to use zero or minimal preload.

However, since excess preload shortens life, radial clearance smaller than the values shown in Table 2 should not be used.
