XSlide bearing is inherently self cleaning

The new XSlide linear positioning stageis aimed at medium-precision applications in production, test and research applications where price and performance are important selection criteria.

A compact, low-cost linear positioning stage with a manual or motorised drive, is now available for stock delivery from motion specialists LG Motion.

Based upon a PTFE bearing system with a simple leadscrew drive, the medium-precision XSlide has a cross section of just 31 x 48mm yet packs a 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 BiSlide positioner featuring a hard anodised bearing rail with an opposing 45 degree 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 1mm 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.
