210 www.danahermotion.com RoundRail Linear Guides are the non-driven building blocks for linear slide tables. They offer the end user flexiblity to fit specific envelopes by allowing customized separations between shafts and between bearings on shafts to produce higher moment capacity. When combined with ballscrew assemblies, they become a driven slide table. Because RoundRail Linear Guides are offered in a wide range of sizes, bearing types, and mounting configurations, they are typically selected by the qualitative attributes that are most appropriate for a given application (i.e. environmental considerations, mounting footprint). For this reason, we are providing the following selection chart and selection criteria for consideration: Systems Quick Reference Guide Application Criteria End Support Continuous Support FluoroNyliner Side Mounted Dual Shaft Rail Twin Shaft Web 1BA / 1NA 1 CA / 1PA 1 VA 1 DA 2DA 2CA High Loads • • Equivalent Loads in All Directions• • Ultra Compactness • • Extreme Smoothness • • • • End Supported • • • Single Rail • Harsh Environment • Low Cost Installation (multiple rail) • • • • Complete Axis Solution • Available Sizes: Inch 4 thru 24 8 thru 24 8 thru 24 • • Metric 8 thru 40 12 thru 40 8 thru 16 8 thru 16 8 thru 16 Page Number 220/222 225/227 230 233 236 239 Linear Guide Selection Criteria • Load/Life • Smoothness of Travel • Cost of Product • Travel Accuracy • Speed & Acceleration • Cost of Installation • Rigidity • Envelope • Cost of Replacement • Environment Application Examples • Machine Tools • Semiconductor Equipment • Packaging Machinery • Medical Equipment • Automotive Assembly Equipment • Food Processing Equipment
