1 LM SERIES LINEAR MODULE

2 THE LM RODLESS LINEAR ACTUATOR RACO s LM Linear Modules are lightweight positioning elements, which can be easily configured into a wide variety of multiple axis motion systems. Possible configurations include single axis driven / idler, parallel linked single axis, XY and XYZ systems. The LM is engineered for carriage speeds to 200 inches per second, single module load capacity of 800 lbs. and stroke range of approximately 20 feet with a single extrusion. Further detail of the LM design and benefits to the motion system builder are listed below. DESIGN FEATURES Features Benefits T-Slots & fasteners Selection of drive stations Mechanical or inductive switches High strength steel reinforced belt Secure mounting; Multi axis configurations Customize to the application Home reference & over-travel protection Axial forces capacity to 400 lbs Cogged belt & pulleys machined to be Repeatability of 0.003" to be 0 backlash Precision extruded 6063 alloy Machined HDP (Delrin) treads & ball bearing wheels External adjustment of belt & wheels Belt seal & sealed pulley bearings Travel to 20 ft without splices Normal loads to 800 lbs. Side loads to 400 lbs. Easy maintenance Service in contaminated environments 2
