Lee Linear, a manufacturer of linear motion components, offers a variety of combinations of individual shafts and rail components. Lee Linear offers ready-to-mount linear systems that can be easily incorporated in almost all drive control applications. U.S. manufactured aluminum shaft support rails in standard lengths of both 24″ and 48″, are used in shaft rail assemblies as economical methods for mounting case hardened and precision ground 60 Plus or 440C shafting. The assemblies conform to industry specifications and provide stable and highly efficient linear motion guidance for continuous or intermittent load operations. Shaft and rail systems are available in six standard configurations, which incorporate a single, double, or twin pillow block. Either two cast steel support blocks or an aluminum rail can support the carriage plate. The patented Lee Roller Bearing Pillow Block provides for self-alignment capabilities, easier clearance adjustment, and better corrosion resistance with longer life expectations and operations at higher speeds. Systems are available with either the Roller Bearing Pillow Blocks or with Precision Plus self-aligning linear ball bearing pillow blocks. ‘‘Optimizing a system to obtain a maximum economic advantage can be challenging,'' said Lee's CEO, Alan Haveson. ‘‘Lee's shaft rail assemblies and systems provide cost-effective solutions. With our larger rolling diameter pillow blocks, we are able to provide smooth and consistent operations even at high speeds.''
