The Monowalker fatmate hiking cart will run on the best available ball-bearing technology. The special features of these new ball-bearings: A polymer material is molded into the free space of the bearing, forming a narrow gap around the rolling elements and raceways, enabling the bearing to rotate freely. The polymer matrix has a porous structure, with millions of micro-pores, that hold the lubricating oil retained by surface tension. In operation, oil is released from the material into the narrow gaps between it and the bearing components, thus providing effective minimum quantity lubrication.

Bearings filled with Oil are lubricated for the life of the bearing and contain two to four times more oil than bearings using a conventional grease fill. Solid Oil cannot be washed out and virtually fills all the free space, thus limiting the amount of dirt and contamination that can enter the bearing. The polymer filling physically supports integral seals, reinforcing their effectiveness under wash-down conditions. www.monowalker.com
