Our 5/8″ x 1-3/8″ Standard Steel Ball Bearings for Front Hubs are made with low contact seals, with little to no grease (unless noted) for free spinning.

 We recommend oiling bearings every race day with a bearing oil like Lubtek or TRI-FLO, not a penetrating oil. The 5/8 ID Bearing is the most commonly used bearing for most modern LTO(Left Turn Only) Racing Go Karts and Racing Lawnmowers. These bearings are replacements for the 2531 5/8 Front Hubs.
