The Bont Inline Bearing Press! Getting bearings in and out of aluminum hub wheels is not easy, so BONT has developed a larger bearing press that is designed for 100mm, 110mm, and 125mm wheels. This inline skate bearing press can also be used for scooter wheels. This skate bearing press makes it easy to insert and remove 8mm 608 (standard) and 688 (mini) bearings from your inline skate wheels. Use this as an 8mm Quad bearing press too!
