The BG15 is a compact ball screw linear actuator in the BG series, designed for high-precision positioning with a height of 15 mm. It integrates a precision ball screw and guide block, with positioning repeatability of ±3 microns for high grade and ±1 micron for precision grade, and backlash of 5 microns or 2 microns respectively. Available in configurations with one or two long blocks, it supports strokes from 75 mm to 200 mm and includes options for a top cover, bellows, proximity sensors, positioning pin holes, and special greases. Mounting dimensions and stroke limits are defined for model variants BG15A and BG15B, with no top cover or with a top cover and sub-table.
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 linear actuator 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.
