NIPPON BEARING
The NB ACTUATOR is a compact single axis linear actuator which integrates a slide guide and precision ball screw. BG type offers compact dimensions and 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.
Reduced installation time
Adjustment-free design that integrates linear slide guide rail and precision ball screws.
High rigidity in a compact package
They feature a unique U-shaped linear slide guide rail and a four-point contact configuration.
High positioning accuracy
Precision-machined components such as a linear slide guide rail, linear guide block, and ball screw provide accuracy.
A space-saving design
BG single-axis linear stage actuators can be used in compact applications where other positioning tables won’t fit.
Sizes and Options
BG linear motion actuators are available in six different sizes and multiple rail lengths. As well, four block configurations are available: single long, double long, single short and double short. All products are available in one of two accuracy grades:
- High grade
- Precision grade
While BG high-rigidity linear actuators are sufficient for most applications, precision-grade products deliver overall improvements in positioning repeatability, positioning accuracy, running parallelism and backlash, which are necessary for use in high-performance environments.
Other options available for BG high-speed linear actuators include:
- Top cover or bellows for additional protection against dust
- Mounting brackets for use with various electric motor types
- Limit sensors, including slim-type/compact photomicro, close-contact-capable or proximity sensors
- Positioning pin holes on the side block or subtable
You’ll find a complete list of product options and configurations by downloading the available BG linear actuator catalog. One of our in-house engineers would be happy to help you assess your needs and determine the best possible iteration of this award-winning product.
