Model RS rolling ring linear drives have zero play when the shaft is rotated – even during reversal. The threadless shaft won't clog or jam. If the system is somehow overloaded, the shaft simply slips instead of churning and grinding. * Use for positioning & reciprocating linear motion applications * Smooth movement; ultra-low maintenance * Example applications: material handling machines, test and measurement devices, x-y table movement, packaging & converting equipment. * Drives available separately or on shaft in custom assembly. * Wide range of sizes for varying linear speeds & axial thrust
