Pentax DA* 55 continuous spin focus ring?

Is it typical for the focus ring on the Pentax DA* 55 to continue rotating after it has passed the 0.45 m mark or the infinity mark on the lens barrel? I purchased a used lens and the focus ring keeps on spinning. My other lens (DA 55-300, DA 18-55mm) have focus rings that come to a firm stop once they have reached either end of the focus ring travel.

Perfectly normal. The DA* line have a clutch focus that allows you to manually focus the lens even while auto focusing is selected.
