As shown in the figure on the left, the bushing can be easily removed by screwing a bolt into its tap (N) and extracting it.
■ When using
● Dimensions when setting
When assembling, if the matching taper is large, it may be necessary to adjust the height of the taper so that they fit more tightly, but if the matching taper is small, it is necessary to take sticking of the pin into consideration. At 1°taper (also 3°taper in some cases), sticking can be avoided by setting them slightly afloat as shown in the figure on the left. When the angle is small, the creep of the height (a in the left drawing) against the width (b in the left drawings) is also small, so there is no need to worry about positioning inaccuracies.

• Before using a TPNC (match mark type), align the match marks. • When selecting a pin independently, use a combination of a pin and bushing of the same accuracy.
