Based upon the highly successful BiSlide - a new smaller and compact linear stage with simple dovetail bearing for medium precision positioning applications
A new compact, low-cost linear positioning stage with a manual or motorised drive, is now available for stock delivery from motion specialists LG Motion Limited.
Based upon a well-proven PTFE bearing system with a simple leadscrew drive, the new medium precision XSlide has a cross section of just 31mm high x 48mm wide yet packs an impressive dynamic load rating of up to 15.9kg with eight travel lengths from 50 to 750mm.
The design is essentially a smaller version of LG Motion's successful BiSlide positioner featuring a hard anodised bearing rail with an opposing 45deg dovetail and an adjustable PTFE liner.
The dual dovetail allows even load distribution with a notable impact resistance of up to four times the dynamic loading.
The low coefficient of friction bearing is corrosion resistant and inherently self cleaning.
Available with a hand wheel or with NEMA size 17 or 23 stepper and servo motors, the XSlide has a choice of 1 or 2mm pitch leadscrews in either nickel plated steel or 303 stainless steel.
With a repeatability of 2.5um per 25mm, overall positioning accuracy is 76um per 250mm as standard, with an optional 38um per 250mm higher precision version.
The straight-line accuracy for the bearing system is 25um per 250mm.
Both the bearing and leadscrew have easily accessible carriage mounted preload adjusters to take care of fine-tuning and wear compensation in-situ without the need to remove the payload.
The XSlide uses a simple and efficient cleat mounting system for single stages or X-Y and X-Y-Z assemblies.
This cost saving, flexible feature allows almost any configuration without the need for adapter plates as well as providing a means of payload and fixture mounting for quick and convenient assembly.
The modular construction includes overtravel limit switch options and accessories include cleats, mounting bolts and a special adapter gusset to provide higher rigidity for vertical end mounting.
The new XSlide is aimed at medium precision applications in production, test and research applications where price and performance are important selection criteria.
