CASM electric cylinders The modular electric cylinder system

CASM electric cylinders The modular electric cylinder system CASM electric cylinders are ideally suited to performing fast and powerful linear movements. Unlike pneumatic or hydraulic cylinders, CASM electric cylinders are flexible and thus can be positioned precisely. Furthermore, due to a reduced number of components, the whole system is more cost-effective, resulting in lower energy and maintenances costs. The CASM modular concept enables easy connection to your preferred motor and control system. This can reduce design and programming costs considerably. Thanks to high-grade materials, a sealing system with IP54S level protection, and high-quality manufacturing, CASM electric cylinders can also be used long-term even under adverse conditions. The low-backlash design provides positioning precision of up to ±,1 mm. Together with various screws for different speeds and forces, CASM electric cylinders are the optimum solution for a wide variety of applications. Features Customised motor adapter Multi-option modular system Highly energy-efficient Highest levels of precision and repeatability Benefits Use your own controls and motors Easy integration and fast assembly Reduced stock Lower energy costs Worldwide service and support Very secure investment

SKF automation solutions Selection of the linear unit The CASM range from SKF contributes to better performing and more reliable machine operations in a wide spectrum of automated applications. Calculate constant mean load F ml F ml F n S n = constant mean load for lifetime calculation in N = force acting on push tube in N = distance travelled in mm Tailor-made solutions with very flexible choices Thanks to its modularity, the CASM can easily be integrated into your own system. Depending on the needed mechanical performance (dynamic load, speed), a wide range of motors can be selected to match the performance for your application (nominal force, linear speed, peak force, etc.). Calculate lifetime distance L 1 dist Draw the point (L 1 dist FmL) on CASM lifetime selection graph (start with smallest linear unit size) Is the point under the curve? Yes Make a motor selection No Repeat the steps with the next bigger size available How to calculate the constant mean load F ml In many cases, the magnitude of the load fluctuates. In order to calculate the equivalent actuator load, it is necessary to first determine a constant mean load F ml which has the same influence on the L screw as the actual fluctuating load. A constant mean load can be obtained from the formula below: How to calculate the lifetime distance L 1 dist The lifetime distance L 1 dist is defined as the life in km that % of a t sufficiently large group of apparently identical actuators can be expected to attain or exceed. L 1 dist = S total t L,36 ttotal L 1 dist = lifetime distance in km S total = total distance travelled per cycle (both directions) in mm t L = lifetime in hours t total = total cycle time (from one cycle to the next) in s Example: Total distance travelled per cycle: 4 mm Required lifetime: 5 years, 23 days/year 24 h/day = 27 6 hours Total cycle time: 15 s 4 27 6,36 L 1 dist = = 2 65 km 15 Draw the operating point on CASM lifetime chart Example: F ml = 5 N and L1 dist = 2 65 km 2 2 2 1 8 Nominal load (N) Replacement of pneumatics CASM electromechanical solutions are a good alternative to pneumatic systems. With energy savings of up to %, electromechanical solutions result in tremendous savings. Besides, with less maintenance needed and less contamination risks, the operating costs of electromechanical solutions are much lower than for pneumatic systems. Like pneumatic cylinders, CASM linear units comply with ISO standards which makes replacement very easy. Thanks to software monitoring, CASM actuators can be synchronized and positioning is more accurate resulting in higher process stability. F1 3 S 1 + F 3 2 S 2 + F 33 S 3 + F ml = 3 S 1 + S 2 + S 3 + (F min + 2F max ) F ml = 3 Load Load F 1 F 2 F3 S 1 S 2 S 3 Stroke F max F min Stroke 1 6 1 4 1 2 1 8 6 4 2 1 2 3 Lifetime diagram 4 5 Point below the CASM 4 BN curve 6 CASM 4 BN CASM 4 BS 7 8 1 Lifetime (km) In this example, the CASM-4-BN is the smallest possible linear unit.

Selection of the motor CASM Linear units To calculate the mean motor torque, we first need to calculate the mean load F m over the motor running time. Please note that the use of a motor brake can reduce the needed power of the motor. Load F 1 F 2 q 1 q 2 q 3 F m = 3 F13 q 1 + F 23 q 2 + F 3 3 q 3 F m = mean force for motor selection in N F n = force of the actuator, powered by the motor, in N q n = time needed for one movement in percent of the full cycle Example: F 1 = 7 N, t 1 = 2 s, q 1 = 1% F 2 = 5 N, t 2 = 15 s, q 2 = 75% F 3 = 3 N, t 3 = 3 s, q 3 = 15% F 3 If no brake is engaged: F max F m q 1% F m = 3 73,1 + 5 3,75 + 3 3,15 = 5 N In our example, the F m mentioned in the system capabilities for the CASM 4 BN is 572 N while the application has a F m of 5 N. Therefore, the Siemens 1FK734 is the right motor for this application. When using a third-party motor When using a third-party motor, we need to calculate the minimum required rated torque and maximum torque of the motor. M L max F m MM min = F d M L max F max MM max = F d M M min = minimum rated torque required by the motor during the cycle in Nm M M max = highest torque the motor has to reach during the cycle in Nm M L max = maximum allowed input torque of the linear unit in Nm F m = mean load of the application in N F max = maximum load of the application in N F d = dynamic force of the linear unit in N In our previous example: Technical data Unit CASM LS CASM BS CASM BN Screw type Lead screw Ball screw Ball screw Screw diameter mm 1 1 Screw pitch mm 1,5 3 1 Max. dynamic force N 3 7 63 Max. static force N 7 7 7 Max. speed mm/s 6 15 5 Stroke mm 5 to 4 5 to 4 5 to 4 Max. input torque* Nm,5,8 1,4 Max. input RPM* 1/min 2 4 3 3 Max. acceleration m/s 2 1 6 6 Duty cycle % 6 1 1 Lifetime L 1 km 7 see chart see chart Repeatability (same direction and load) mm ±,7 ±,1 ±,1 Operating temperature C to +5 to +5 to +5 Humidity % 5 5 5 Type of protection IP 54S 54S 54S * Speed and torque of the motor needs to be limited If the brake is engaged during the period q 2 : 4 5 M M min = = 1,31 Nm 1 55 Performance diagrams CASM F m = 3 7 3,1 +,75 + 3 3,15 = 337 N When using a SKF tested motor When using a SKF tested motor, make sure that the F m value mentioned in the system capabilities is equal to or higher than the calculated F m value of your application. 4 7 M M max = = 1,81 Nm 1 55 The rated torque of the motor should be at least 1,31 Nm at the needed speed, and the absolute maximum torque of the motor (or peak torque) must exceed 1,81 Nm. Attention: The dynamic torque of the motor may vary according to the speed. Please confirm that your motor is able to reach the needed speed, acceleration and max. torque for your application. 3 25 2 15 1 5 Force (N) 1 5 1 5 1 5 Radial load (N) 7 6 5 4 3 2 1 Nominal load (N) for CASM-4 with Siemens motor 1FK734 Unit Peak force F m CASM 4 LS N 6 6 CASM 4 BS N 2 375 1 21 CASM 4 BN N 155 572 Configuration For quick and easy selection, please use the Actuator Select application on www.skf.com/casm 1 2 3 4 5 6 Speed (mm/s) Speed force diagram CASM LS No limitation for ball screw types (max. load at max. speed). 1 1 2 3 4 5 6 7 8 Position (mm) Radial load diagram The radial load acts perpendicular to the moving direction. 1 2 3 4 5 6 7 Lifetime diagram CASM BN CASM BS 8 1 Lifetime (Km)
