ABSTRACT:
A positioning device includes a first member and a second member. The first member defines an alignment axis and has a male portion. The second member is separable from the first member and defines a female portion for mating with the male portion along the alignment axis. A bearing mechanism is coupled to the female portion for reducing friction when the male and female portions mate and the bearing mechanism moves between first and second positions relative to at least one of the members. A resilient member is retained by the second member for resiliently supporting the bearing mechanism between the first and second positions. A retaining pin is coupled to the bearing mechanism and is retained between the second member and the resilient member. The retaining pin reacts against the resilient member as the bearing mechanism moves between the first and second positions.
