This new series consists of two recirculation systems. One is brand new developed high speed deflector type ball screw for smaller leads (5 ∼ 30 mm). The other is end deflector type ball screw for higher leads (20 ∼ 40 mm). Both allow very high d·n, value up to 160 000.
High load capacity
1.4 times dynamic load rating is achieved by applying TF treatment to ball screw for machine tool.
The TF treatment has already been applied to the Bearing industry several years ago and as well as to our high load capacity ball screw for injection molding machine (except dia 25 ball screw, 32 lead 5 and 40 lead 5). It contributes to high cycle operation with long life of ball screw.
Low variation of torque
By using NSK own simulation technology for ball motion we could develop better ball recirculation systems. The low torque variation contributes to improvement of machined work piece surface.
Low noise technology that has been used for end deflector type is applied to deflector type. Other low noise technology that reduces the noise from raceway is applied to this series whose accuracy grade is C5.
