Abstract:
1. A shock absorbing device comprising: a first stem having a tubular wall extending between a first end and a second end, and defining a longitudinal axis; a second stem having a tubular wall extending between a first end and a second end, and configured to receive a portion of the first stem; a guide member having an outer surface configured to prevent the first stem from rotating relative to the guide member; a shock absorbing structure disposed between the first stem and the second stem; a bearing device including a tubular bearing cage disposed between the first stem and the second stem, and at least one ball bearing rotatably received in the tubular bearing cage, wherein the bearing device is configured to rotatably guide movement of the first stem relative to the second stem along a direction substantially parallel to the longitudinal axis of the first stem and prevent radial sway between the first and second stems; and a generally tubular pad provided in frictional engagement between an inner surface of the first stem and the outer surface of the guide member.
