A shock absorbing device may include a first stem having an inner surface extending along a longitudinal axis, and a second stem configured to receive a portion of the first stem. The shock absorbing device may also include a guide member having an outer surface configured to prevent the first stem from rotating relative to the guide member. The shock absorbing device may further include a shock absorbing structure disposed between the first stem and the second stem. The shock absorbing device may further include a bearing device 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. |
