기능

• Circulation Type [Top Type]
• A system in which a horseshoe-shaped material is passed between adjacent pitches (leads) and circulated
• Suitable for small leads.
• Nut outer diameter is small and compact design is possible.
• Unrivaled high precision
• High precision achieved with the grinding method and measuring equipment developed by NSK
• Durable
• Uses highly clean alloy steel for excellent durability.
• High rigidity without backlash
• NSK ball screw adopts gothic arc groove shape to minimize clearance between ball and groove.
• In addition, the clearance can be reduced to zero by applying preload, and there is no backlash.
• In addition, by controlling the preload amount, rigidity according to the operating conditions can be obtained.
• Even when preload is not applied, the clearance between the ball and groove can be minimized, so the backlash is very small.
• Smooth operation and high efficiency
• Circular grooves cause the ball to wedge into the grooves of the nut and screw shaft, whereas gothic arc grooves do not.
• This, combined with the low friction inherent in the ball screw, allows for smooth and highly efficient movement conversion.
