TKS & TKB Rodless Actuators TKS & TKB SPECIFICATIONS ACTUATOR SIZING BENDING MOMENTS AND LOADS * Bending moments & load specifications are based on 200,000,000 (5,000 KM) linear inches of carrier travel. Breakaway torque will increase when using the Auxiliary carrier option. When ordering, determine your working stroke and enter this value into the configuration string. Overall actuator length will automatically be calculated. Deflection Considerations: In applications where substantial Mx or My moments come into play, deflection of the cylinder tube, carrier and supports must be...

BELLOWS STROKE REQUIREMENTS MAXIMUM AVAILABLE STROKE FOR BELLOWS OPTION TKS BELLOWS COVER OPTION INCREASES OVERALL ACTUATOR LENGTH BY 0.508 x STROKE MAX. DISTANCE BETWEEN PLATES (in) "L" Actuator body theoretical axial deflection will not exceed .015 in (0.38 mm) Proper and adequate lubrication is essential for normal operation of TruTrack actuators. Poor lubrication will cause quicker wear and decrease service life of the actuator. For general use, lubrication should be performed at intervals of 4,000,000 linear inches of travel (100 km) or once every year, whichever occurs first. However,...

TKS Rodless Screw Drive Actuator ACME SCREW/NUT COMBINATIONS TKS ACME SCREW CRITICAL SPEED CAPACITIES LINE COLOR * For Acme screws, maximum thrust is the maximum continuous dynamic thrust subject to Thrust x Velocity limitation. Dashed line represents maximum stroke for screw selections. SCREW TYPE DESCRIPTION SN Solid Nut BN Ball Nut SPEED (mm/sec) SPEED (in/sec)

TKS Rodless Screw Drive Actuator ACME SCREW/NUT COMBINATIONS TKS ACME SCREW PV LIMITS 100 SPEED (mm/sec) SPEED (in/sec) * Maximum thrust is the maximum continuous dynamic thrust subject to Thrust x Velocity Limitation. PV LIMITS: Any material which carries a sliding load is limited by heat buildup. The factors that affect heat generation rate in an application are the pressure on the nut in pounds per square inch and the surface velocity in feet per minute. The product of these factors provides a measure of the severity of an application. P Thrust (Max. Thrust Rating) V Speed (Max. Speed...
