 Stieber ASNU25 = Tsubaki TFS25 one-way bearing is free to rotate one direction, while in the other direction on a bearing lock. 
 Features: One-way bearings entity GCr15 bearing steel, hardness after heat treatment HRC61-65, bearing small size and high carrying capacity, there is sufficient space for the storage of grease, may have come a long lubrication intervals. One-way bearing and physical metallurgy can complete the one-way bearing shaft by driving force "locked" to avoid the traditional one-way bearing outer ring pressing "lock" the problem of inadequate performance.
