Servo pillar CPSM The irst telescopic pillar with servo-power for industrial applications High load capability High speed capability Virtually maintenance free
Telescopic pillars CPSM are the ideal solution to combine strong guiding functions with linear movements. The robust, manually adjusted and virtually backlash-free aluminum extrusions are able to carry high excentric loads in push and pull directions. To provide enough power to lift and lower heavy weights with high speed, the pillars are equipped with brushless DC or servo motors. Of course, SKF also supports the usage of preferred motors with a customizable motor interface. Optional brakes and damping elements are key features that allow an effective usage in heavy duty industrial applications. 2 5 1 3 4 10 6 Design 8 1 Customized top plate 2 Optional damping system 3 Backlash-free long lasting guiding pads 4 2 or 3 section extruded aluminum guiding tubes 5 High eficiency ball screw 6 Preloaded bearing arrangement 7 Low friction worm gear reduction 8 Optional electromechanical brake 9 Standard or customized motor interface 10 Motor (Brushless DC or servo AC) 11 Customized bottom plate 9 7 11 Features and benefits High dynamic servo or brushless DC motor for high speed up to 100 mm/s High performance ball screw for high load capacity up to 5 kn Extruded alumium proiles for a very robust design Manually adjusted gliders for very high stiffness and high excentric loads Encoder system of the motor and high quality gearbox enable high positioning accuracy and high repeatability (0,1 mm) High nominal power of the motor allows for high duty cycle of the pillar Customized motor adapter for highest lexibility (max. motor diameter 90 mm) Customized top and bottom plate to it most of the applications Customized aluminum proile colour (anodized) to it application design needs Optional brake to release the motor when it s in position and to increase the duty cycle Preloaded bearing arrangement also for ceiling mount applications (only available without damping system) The optional damping system protects the inner parts of the servo pillar in case of hard impacts. This might be helpful for applications where goods are loaded on the top of the pillar and could create high peak loads. With this option, the retracted length increases by 65 mm. 2

Optimized for your application Factory automation sorting, diverting I n d u s t rial processing lines require constant dynamic positioning to manage and sort different types and sizes of products. CPSM servo pillars represent an innovative solution to easily realize sorting stations in an effective way. By combining the actuation function with the linear movement guidance, customers can realize the lifting function simplifying the mechanical construction, reducing also the design and assembly time. The compactness of the pillar also ensures a minimized footprint in the machine, resulting in a smaller processing line. Last, but not least, the in-built mechanical and electrical connections allow plug and play installation and removal, simplifying the future maintenance operation at the end user sites. Factory automation automotive The high controllability and robust construction make a CPSM pillar the ideal solution for realizing a smart chassis levelling function in automotive car transfer units. The need of handling different types of car chassis on the same line requires a lexible system setup that allows a quick resetting with precise positioning. The optional integrated dampening system protects the pillar from mechanical shocks during the loading and unloading phases, ensuring high reliability and longer lifetime in operation. The usage of customer-deined servo motors allows for easier integration into the control network, reducing the commissioning time of the transfer unit. 6
