NSK NN4921MB bearing

105x135x40

Overall, the cycle time of this project, from first contact to mass production (in-cluding the 15-week test phase) was just under 32 weeks. The time could also be kept so short because the bearings were manufactured in one of NSK's German manufacturing sites specialising in special bearings.
