Evarix "Roller Screw"
Higher rigidity than ball screws! Design can be lightweight and compact!
By using rollers as the rolling elements, surface contact is achieved, resulting in longer lifespan and higher rigidity compared to ball screws. Additionally, the allowable load per size increases, enabling lightweight and compact equipment design. 【Features】 ■ By innovating the thread shape of the rollers, "surface contact with low friction," "high surface pressure resistance," and "high load capacity" are realized. ■ Since it is not a recirculating type, it can handle shock loads and is suitable for high-speed and high-acceleration applications (SR & ISR series). ■ There is no contact between rollers, resulting in less wear and reduced likelihood of failure. ■ Robust design prevents slipping even during high acceleration. ■ Ultra-low lead options are available (SV series).
