Hardcase HNKIT50 - Wheel and axle kit for HN52W case (official spare part for axle end)

The Hardcase HNKIT50 is a replacement kit designed to restore the rolling system of the Hardcase HN52W hardware case at its thru-axle end . The kit combines two Heavy Duty wheels and a steel axle with locking screws, following the official Hardcase parts specifications for this model. The wheels — 75 mm in diameter with 8 mm bore — offer quiet rolling and good grip, while the 405 × 8 mm axle (with two screws ) ensures a solid fit. It is the recommended solution to restore the HN52W to a smooth and reliable ride without replacing the entire case.
