Ball Screws

Nut Cooling Ball Screw

There are several sound arguments for maintaining a stable temperature below 40°C in ball screws to guarantee the utmost precision. This is because the fast motion of the nut raises the operating temperature and thereby prompts changes in running behaviour. A temperature increase of just 10°C causes a 1-metre-long spindle to stretch by 120 µm, which means that the machine tool can no longer deliver the necessary precision. Our specially developed nut cooling system drastically reduces heat generation, enabling consistent machining results. This means the necessary operating temperature can be maintained >>

Ball Screws - DIN Standard Series

NSK adds Ball Screws that accord with DIN standards widely used throughout Europe in a new lineup of standard stock ball screws >>


Grinding machines

Zero tolerance for contamination

Modern grinding machines such as cylindrical, surface, tool and jig grinding machines are used to process a wide range of work pieces. They have to maintain very precise tolerances and roughness values. Over time, the lubricants and coolants used become contaminated. This causes severe abrasive wear to the machine’s components.

Compact, robust ball screws from the BSS series together with NSK’s innovative X1 seal concept ensure low-friction movements and high speed sealed ACBB make sure, that grinding machines run reliably. As a result, servicing intervals can be substantially extended, reducing maintenance costs.


 

Ball Screws

Ball Screws - X1 Sealing concept

Ball Screws - X1 Sealing concept

The X1 concept provides an ideal external and internal seal for ball screws. The inside of the seal prevents lubricant from escaping, while the outside stops contamination from penetrating the body of the nut. This increases the load rating and rigidity of the ball guides. On top of this, the ball screw’s liquid-cooled nut enhances power density >>

Ball screw II. Generation - High-speed, Low noise

High speed and low noise Ball Screw Generation I offers peak noise reduction of at least 6 dBA over conventional ball screws. In Generation II, the speed has been increased at least 40% whereas the noise caused by the raceway has been reduced >>

Ball Screws - High Durability

Even under unsettled conditions, the High-Durability Ball Screws show much better resistance to wear.  Improved oil film reduces wear due to contact between balls and raceway groove >>

Forming

Demands for increasingly efficient energy conversion are leading to electromechanical drive concepts in various branches of industry. The process of metal manipulation – i.e., stamping, forming, and bending – has a major impact on how mechanical components are designed.
Linear guides, ball screws and bearings are replacing hydraulic drive solutions because they mobilise power reserves and help to significantly reduce driving axles. NSK’s cooled ball screws also increase the amount of heat which is transferred.

Typical machines using our products are Laser machines, bending, press brake, presses or punching.
