NB actuator
NB's BG Type is a compact single axis actuator which integrates a Slide Guide and Precision Ball Screw. BG Type offers compact dimensions, which outperforms conventional positioning tables. This is made possible by a unique "U" shaped Guide Rail and Slide Block which provides multiple functions of a Guide Block and a Ball Screw Nut combined into a single unit. The "U" shaped Guide Rail design offers a high rigid structure resistant to bending. This structural feature allows for integrated frameworks of machinery or equipment. Additionally, the Slide Block contains 4 ball circuits which delivers high load capacity, high accuracy and high rigidity.
NB actuator is available in also size 15!
Advantages
Adjustment Free:
The integration of the slide guide and precision ball screw eliminates complex precision adjustment and reduces installation time dramatically.
High Rigidity:
"U" shaped guide rail provides very high rigidity despite its compact configuration and can be used for one-end supported application.
High Accuracy:
BG type contains four ball circuits and four-point contact ball grooves which contributes to its high rigidity. The combination of precision ground guide rail, slide block and precision ball screw provides high positioning accuracy.
Space Saving:
In comparison to conventional positioning tables, the BG type allows for compact designs and dramatic space saving. The "U" shaped guide rail and integrated slide block / precision ball screw nut make this possible.
